It is almost like the applet is refreshing it'self every move. Is this happening to anyone else?

But the puzzle is definitely refreshing every time you drag the puzzle to rotate it. This causes a significant freezing if many steps have been made. Try to apply the algorithm like [U, R, D, L]x1260, which gets the Rubik's cube back to the initial position in 5040 steps. After this, when I drag the cube, the cube freezes for a couple of seconds with cpu running 100%. I've seen this phenomenon on Firefox under Windows XP and Safari under Mac OS X. I guess the applet is reloading the record of all steps that have been made.

Woot! The stats chart changed from top 10 to top 20 in puzzles solved, and that puts me on the charts. Now i wont have to stay up countless hours trying to figure out more puzzles that i cant solve yet.

I noticed that my Pentultimate solve using macros was colored differently on the high score list, although the time wasn't modified and it was ranked first. There doesn't seem to be any penalty for using macros at the moment.
I just did a 4:56 Pentultimate solve with no macros. Will this replace my normal solve? I'm not sure.

I just did a 4:56 Pentultimate solve with no macros. Will this replace my normal solve? I'm not sure. It's difficult to estimate a fair amount of penalty. So, as a temporary mesure, I implemented a penalty of 1 sec per move(one primitive move and not a macro). For example, for a statement of "[a,b,c]x1000", a penalty of 3000 seconds is charged. The rate can be modified. On the scoreboard, a time with macros is shown with different bg color followed by penalty amount.

Alrright Julian i've set you a chalange. It hasn't come up on the score board yet but i got a pentultimate solve of 161 moves i was up to the last 15 corners in 26 moves and was VERY carefull with my 3 cycles sometimes purposly only solving one corner so that i was left with a perfect 3 cycle to finish not a 22 swap. Ialso gave the super pentultimate a seccond solve but i only beat my first solve by a few moves. I think with allot of luck a sub 150 pentultimate solve is possible. On another note the anoying white flash i was getting is gone and i'm now thinking it was my computer struggleing with the 40 degree celsius heat and not a problem with the site which is good.

You can choose whether to orient the corners at the same time (trickier but more effecient) or to just permute them then orient them in pairs pure using a (5,1) commutator. 4. If you end up with a single twisted corner the simplest way to finish the solve is to twist the corner into its correct position, then repeat steps 13.

I had another look at your method (back on page 24) and it made me think i should learn some more algs. I do the exact same steps as you however i mostly only use 2 algorithms. I use R U R' U R U2 R' D (or D' or D2 and so on) R U2 R' U' R U' R' D' (16 moves) for the corners and sometimes i have to use ALLOT of setup moves. For centers i use just R' L R L' but sometimes if i get a three cycle i refer to your center algs. So i'd say i'm doing pretty well for only having 2 main algs . I also got within 5 moves of your super pentultimate solve which i'm quite happy with(for center orientation i rely compleetly on your algs. Thank you very much for those). I was also wondering if you had any hints when it comes to how you got your starminx solve so low because i suppose it is to me kind of like what the pentultimate is to you I.E the first hard puzzle i solved on gelatinbrain. No matter how hard i try my best solve is still 100 moves more than yours and i don't even want to think about how Matt Galla got 414

I used the same commutator as you up until last May. It's funny how Rubik's Cube algos are useful with the Pentultimate. Sune swaps a corner in half of the Pentultimate in 7 moves. FURU'R'F' does the same thing but one move quicker. If you try to optimize setups you'll definitely save moves. Also you'll sometimes find that you can set up the 3rd corner of a cycle 2 different ways in 2 moves, but one gives a "good" orientation (cycle in 1718 moves), while the other gives a "bad" orientation (cycle in 2122 moves). I did a solve of 158 moves tonight. I've been experimenting with a variation of my usual method. After solving 6 centers and 5 corners, I then use dirty algos of 67 moves to place some of the next group of 5 corners individually, to finish as much of half of the puzzle as possible before permuting the last 6 centers. These algos only work where the corner is not adjacent to where it needs to go. It costs 6 moves to push an adjacent corner to a nonadjacent position, which is a bit expensive so I just solve the nonadjacent corners. None of my centerswapping algos affects more than 2 of these corners so it is usually possible to finish the centers as normal without messing up the extra solved corners. I've also found an alternative cycle of 3 final centers which only affects 1 corner of the other half, in 8 moves. My idea is that solving individual corners in an average of just over 7 moves is narrowly beating the average corner cycling move count, and every saving helps. If we could solve all the centers and 10 corners in around 65 moves, we'd still need 1 other corner to be luckily solved to be able to solve the last 9 corners in 4 cycles to beat 150 moves. Maybe 1 time in 100? Elwyn wrote: I also got within 5 moves of your super pentultimate solve which i'm quite happy with(for center orientation i rely compleetly on your algs. Thank you very much for those). You're welcome; I'm happy those algos have been helpful.

No matter how hard i try my best solve is still 100 moves more than yours and i don't even want to think about how Matt Galla got 414 1.1.5 least move hints: 1. Edges. Place 5 around a face, then the next ring of 5, then a few more where easily done, then carefully minimized setups and (1,1) commutators to finish them 23 at a time, like finishing the Pyraminx Crystal. 2. Centers. Cycle with (3,1) commutators. 3. Triangles. Cycle with (4,1) commutators. Or for more of a hint, (4 moves 2gen, slice move)! It was Noah who first posted this algo. (It can't be used for 1.1.25, but it's great for 1.1.4  1.1.6.) The key thing with the triangles is to solve them 3 at a time as much as possible. I try as many 3cycles as possible involving a particular color, then move onto an adjacent color, until I can only solve pairs for a while. When solving the pairs I try to gradually finish adjacent colors, while also looking for any new 3cycles that open up. Also it's usually possible to set up the triangles up with quite a short sequence of moves; I take my time and experiment during the solve.

Hahaha just yesterday i was trying to think of a good way to solve those next 5 corners before the last 6 centers.turns out you were thinking along the same lines and beat me to it aswell. I didn't spend too long looking for a way though. I had a look a FRUR'U'F' and it does seem like i could save around 12 moves a solve with it which is good. As for 1.1.5 it seems we solve it with almost the EXACT sam method however i think you are allot more carefull when it comes to the pyraminx crystal edges as i mostly only solve them one at a time. I also did a solve of 1.1.6 focusing almost entierly on speed (and got seccond place ) but i also beat my last fewest moves solve which took me around 3 hours of painstaking conentration in the same solve just because i've had so much pentultimate practice

A couple of months ago I solved all tace turning octahedra with 2, 3 and 4 layers, but I never got a good algorithm for some of the edge triangles, and had to do weird things on the 4 layer ones, but with the knowledge I had back then Icouldn't do the 5 layer ones. Today, I decided to review the 5 layered FTO's, and came up with an algorithm So I immediately solved all 3 of these, and now have 122 puzzles solved, passing Campbell by 2 solved puzzles, which makes me 5th place. But I'm sure, if Campbell, Noah, and other geniusses who are 'on a break' come back and see all the new puzzles, I would be passed easily again

3.4.8
Suggest solution method:
1) Permute the centers using a few Skewb moves.
2) Solve 4 corners around a face using 3x3x3 moves and check the orientation of the remaining 4 corners. If the corner orientation is an invalid 3x3x3 orientation, then pick a corner that needs to be twisted to fix the problem: If FUR needs a clockwise twist, FUR ULF ULB RUB (or similar). If FUR needs a counterclockwise twist, FUR' RUB' ULB' ULF'.
3) Solve like a 3x3x3 using face moves only, placing as many 2color pieces correctly as possible along with the corners. It's theoretically possible to be very unlucky and only be able to place 8 edge pieces correctly, but usually 11+ can be solved as part of this stage.
4) Cycle the remaining 2color pieces with nonpure (5,1) commutators.
5) Cycle the big triangles with pure (6,1) commutators.

It got me a lot further, but now I've hit this bump in the solving road. I have just one corner turned. It seems that i want to just keep twisting back and forth. i kind of understand what your saying to do but am just too afraid to stuff this all up. edit: went for it and got it in just under 4 hours and under 2500 moves, thanks for the help again

I just solved 1.3.1. Attachment:
1.3.1.JPG [ 79.4 KiB  Viewed 3331 times ]
time: 01:23:22, moves: 2335 Solution outline: 1. Put the centers in their correct spots, very easy. 2. Solve all corners with just faceturns, and hope you donÂ´t wind up with one twisted corner, which will be the case 2/3 times you try. With my knowledge, I had to start over if one corner was twisted. 3. Find threecycle that switches the thin triangle pieces and one that switched the wide triangle pieces, and apply it. The threecycle I came up with for the wide triangles is far from perfect. It is like a (18,1) commutator (not sure) and added a lot to my move count. But still, I solved it!

I have a question about the "puzzles solved" statistics. To solve a certain puzzle, if I'm not fast enough to be in the top 50 time ranking and not efficient enough to be in the top 50 fewest step ranking, will that puzzle be counted in the "puzzles solved" statistics? Thanks.

Thanks. "Yes" is the answer to your question. For example, the first time I solved the Gigaminx, even though both my time and move count were outside the top 50, my total solved count went up by one. (My second solve just squeezed me into both rankings, then I got pushed out of both again literally a few days later!)

Here's a (7,1) commutator to solve the wide triangles pure: EDK,C',ABC,AEF,ABC',C,EDK', D', EDK,C',ABC,AEF',ABC',C,EDK', D Good luck! It's tricky solving the wide triangles at the end. It's much easier to solve in the order: corners, wide triangles, centers, thin triangles. If you feel like more of a challenge to save moves: wide triangles, corners, centers, thin triangles.

I solved 1.1.19 in 23:19... beating Daniel Devitt's record by just over an hour I don't know about other people, but I find the "reduce to 3x3/megaminx" style puzzles relatively easy, so I'm confused why more people haven't done (and gotten good times on) puzzles like this, 1.3.1, 3.4.6, 3.4.7, etc. Tips for pairing up edges on these types of puzzles (if edges come in 4 pieces and each slice moves two of them):  The basic move is a threecycle of centerwing groups, but if you use an edgeonly 2flip (mine is F U' R U R' U F' U') you can also do a 2cycle of centers and a 2cycle of wings.  For most of the edge groups, you can pair each wing up with a center of a different color separately, and then pair those pairs together at the end.  For the last two or three edges, observe that using the edge flip algorithm you can swap only two wings if you can just setup the centers to be the same color. So just move the centers around until the pairs of centers match the color pairs on the wings that are left, and then use this technique to solve the rest of the wings two at a time.  If you ever get two edges swapped in the end, you can do u' [flip edge] u2 [flip edge] u'.

Ok IÂ´ll take on your challenge Michael I did 1.3.1 already, and now IÂ´ll try 3.4.6 I figured out this pure 3cycle for the wide triangles near the corners already: DRB,U,F2,U',R',F2,R,B',R',F2,R,U,F2,U',B, DRB',R',L,F2,L',U',F2,U,B2,U',F2,U,L,F2,L',B2,R I know, itÂ´s terribly long and adds a lot to your move count, but hey, it works edit: that got me this far: Attachment:

I have no idea on how to do the triangles in the 3x3 edge pieces. Knowledge of a simple pure 3x3edge cycle (that I donÂ´t have) would help. edit2:and also a master skewb center twisting or cycling algorithm

My 3cycle on 1.3.1 for the wide triangles was: AEF,C,B'2,C',A',B2,A, D,A',B'2,A,C,B2,C',D', AEF',B,I'2,B',F',I2,F, A'2,F',I'2,F,B,I2,B',A2, So julians is probably better

3.5.1 (2x2x2 + Little Chop)
1. The pieces are in two orbitals. Choose the "lefthanded" or "righthanded" pieces to solve first, and make some intuitive moves to solve as many as possible.
2. Solve the remaining pieces in your chosen orbital using nonpure (8,1) cycles. Hint: Try to isolate a piece in a Little Chop half of the puzzle with a (3,1) commutator, not caring if one or two pieces from the other orbital stray into the same half.
3. Solve the pieces in the other orbital using pure (12,1) cycles. Hint: Try making a couple of face moves either side of a mirror image of the same (3,1) commutator you used in stage 2, to see if you can isolate a single piece in a Little Chop half of the puzzle without any pieces from the other orbital straying into the same half.
I took 362 moves using this method.

I used the algorithm bar a lot for this one. the actual moves I did myself were the 3x3x3 solution moves and setup moves. Solution outline: 1. solve the centers with master skewb moves 2. solve like a 3x3x3, and hope you donÂ´t wind up with one corner twisted. if you do start over 3. solve the wide triangles (which are part of the 3x3x3 corners) with a masterskewbfacesquarecyclealgorithm 4. solve the smaller squares, the ones closest to the centers. my algorithm was: R',U2,R',U',R',U',R2,U,R,U,R2,DLF,R2,U',R',U',R2,U,R,U,R,U2,R,DLF', 5. solve all righthanded smaller triangles (which are part of the 3x3x3 edges) I used a 45move algorithm for this : LDB',UBR,LDB,UBR',BDR,FLU',BLD,RDF',BLD',RDF,DRB',UFL,R',U2,R',U',R',U',R2,U,R,U,R2, BDR,UFL',RDF',BLD,RDF,BLD',DRB',UFL,RUB,DBL',RUB',DBL,R2,U',R',U',R2,U,R,U,R,U2,R, 6. solve all lefthanded ones. I used another 45move algorithm for this: DLF,RFU',DLF',RFU,BUL,FRD',FDL',RBD,FDL,RBD',ULB',DFR,R',U2,R',U',R',U',R2,U,R,U,R2, BUL,FRD',RBD,FDL',RBD',FDL,DFR,ULB',RFU',DLF,RFU,DLF',R2,U',R',U',R2,U,R,U,R,U2,R, As the very experienced puzzlers might have noticed, all of my algorithms for the puzzles that are a combination between 2 puzzles, are a combination of algorithms of both puzzles. Far from optimal, but they work.

Crazy luck solving the Pentultimate (1.1.7)! I solved one half of the puzzle in 70 moves, which is nothing special. But, when I checked the other half: * The other 6 centers were already solved * 2 of the last 10 corners were already solved * 3 of the other 8 corners were sitting in a perfect 3cycle (including orientation) I calculate the odds of all these happening at 1 in 1,944. So I had 5 corners left to solve after 88 moves; 3 corners left after 106 moves; and finished at 123 moves.

With 3.4.6, after the centers I solved the "main" corners and edges like a 3x3x3, then I cycled all the other pieces: big triangles (5,1), small triangles next to edges (5,1) and finally small triangles next to centers (6,1) pure. But now after Michael's hints I want to try reduction sometime to improve my move count.

When I'm solving a jigsaw I like to see more and more solid sky, and house, and field. It disturbs me to see a chunk of sky landing in the field and staying there for a while, with a bunch of grass stuck in the house. Even with puzzles where I feel I understand reduction pretty well, such as 4.1.24.1.4, I still have to go slowly and I feel a bit disoriented during the edgepairing stage. Also, without Doug or Campbell posting here to give reminders and the occasional tutorial on the virtues of reduction, I naturally gravitated back into my comfort zone! Thanks for the hints; once I've finished off 3.1.x I'll reread your post and I'll try to put them into practice.

I feel like, where a normal solution method is about pairing everything up so it matches some kind of static part of the puzzle, reduction is all about pairing pieces up to each other to make blocks. In the middle of a reduction solve, the puzzle doesn't look close to solved in the sense that most of the pieces are where they're going to end up, but rather in the sense that a lot of piece groups are paired up so the puzzle feels very orderly. I find reduction methods easier, actually, because I basically see the puzzle in terms of the puzzle I'm reducing to (and this is way easier once you've got a few blocks set up). Then my goal is just to turn the disorganized blocks into organized ones. This is usually pretty easy (more [x,1] comms and less ridiculous long pure 3cycles) but you have to be willing to move the blocks around freely in the reduced puzzle group. Basically, if you're using long algorithms for a reduction solve, you're probably doing something wrong.
So, in terms of a jigsaw, it's like putting together groups of pieces you can see into small blocks and then later putting those together, rather than just trying to build the entire puzzle in one block. Not an unreasonable strategy if putting blocks together can be done easily.
I guess I have a lot of practice with this approach from solving 4x4x4 and 5x5x5 for speed. Those use reduction too, and that might very well be the thing that makes me feel very comfortable with the idea. I've done very many (thousands) of solves of those puzzles over the years, and I don't expect anyone here to do the same, but getting more or less comfortable with reduction on one puzzle is a big step towards being comfortable with it on every puzzle.

Hey All, this is my first post on this thread (and my first post on this forum!). I am working my way through some of these great applets. I have solved 20 so far. My goal is 40. I suppose if I reach it I'll probably have a better idea for how to tackle the more complex ones and I'll update my goal I solved all of the Circle Cubes (3.1.{7,9,10,11}) except the Circle 2x2x2 (3.1.8). Unlike the other circle cubes where some of the pieces in the circle are connected to each other to create 1 piece with 2 or 3 colors that aren't touching, it seems the circle centers of 3.1.8 are onecolor pieces. It seems the circle pieces correspond to the centers of a 4x4x4. Without the outer layers of a 4x4x4 though I have not been able to figure out how to solve the circle centers. Am I on the right track here? Should I solve the outer 2x2x2 shell first and then solve the circle centers? In all of the other circle cubes I worked from the circle outward.

The centers in the gelatinbrain Circle 2x2 come in pairs and each pair corresponds to an (invisible) 3x3 edge. Good luck.

I looked for pairing to see what pieces they may correspond to on a inner "virtual" cube but I didn't see that they were connected through the cube. From that I concluded that they were 1color center pieces. They certainly didn't move like that though. I still have a long way to go before I start to catch up to you!

Guys, go check out the new face+corner turning cubes, 3.4.113.4.20! GelatinBrain has uploaded 10 new puzzles! Thanks! This is great.... EDIT: I had a better look at all of them, and noticed all of them are combinations of 3x3x3+skewb of 3x3x3+master skewb. But still, all different, and all very hard I did just solve 3.4.11, but as always, with a looooot of moves. But I need an algorithm: I know how to turn 2 skewb faces by 180Â° when they're opposite to each other, but does anyone know a way to do this to the centers of two adjectent faces? It would make these cubes a lot easier for me

Wouldn't a onemove setup do the trick?
You sure did use a lot of moves for 3.4.11, haha. I still suggest reduction  I paired edges with [skewb move, [1,1] edge comm] and paired corners with [skewb move, [1,3] edge comm].

I use a partial reduction. My steps were: 1. get 3x3x3 centers correct with skewb moves 2. check if all corners are turned right(by solving all corners, and if I wind up with one of them twisted, I start over ) 3. Pair up the tiny edgewings 4. solve as 3x3x3 5. get the 3x3x3edgefaces to match the edge wings 6. get the tiny triangles in 3x3x3corners to match the rest of the corners My moves count is so terrible, because I use a combination of 3x3x3 and skewb algorithms (mostly R',U2,R',U',R',U',R2,U,R,U,R2, for 3x3x3, and one skewb turn or an algorithm I use to twist the front and back skewb centers by 180Â°) and I use the algorithm bar to freely. So instead of taking the effort to copy and paste the reverse algorithm for a 3cycle into the bar, I just do two of the original ones. But I donÂ´t care about move count of time, just amount of puzzles solved

I guess the only family missing from the cubes now is vertex+edge hybrids. Picking one of Dino Cube 3.2.4, Master Skewb 3.2.2, or Skewb 3.2.1, and combining it with one of 3.3.1, 3.3.3, 3.3.5, or 3.3.7, that's 12 possible combinations as a start, and I assume that at least a few of those make good puzzles. By the way, Michael, congratulations on reaching a new Gelatinbrain landmark: 1st in Fewest Moves Michael Gottlieb . . . . . . . . 112 Rest of the world . . . . . . . 111 And of course this includes a few tied records not involving Michael, which boosts the world total.

That's a lot of fewest moves records :p Are you sure it's the majority, though? There seem to be 234 puzzles. By the way, according to my calculations, there are 47 nontrivial puzzles composed of a cube with one corner and one edge turn:  3 of type 3x3x3 + trivial corners  15 of type 3x3x3 + shallow dino  1 of type 2x2x2 + shallow dino  1 of type 3x3x3 + dino  1 of type 2x2x2 + dino  21 of type 3x3x3 + master skewb  1 of type 2x2x2 + master skewb  3 of type 3x3x3 + skewb  1 of type 2x2x2 + skewb Gelatinbrain only has 17 of these, so there are many more possibilities yet

Yes! More circle cubes! I solved the new 4x4 variant, but in order to do the new 5x5's I really need to learn some 5x5 supercube algs... That ennoying last center!

Yeah I love the circle cubes too. Thanks gelatinbrain! Sjoerd wrote: I really need to learn some 5x5 supercube algs... That ennoying last center! My strategy is really slow and has a high move count but doesn't require anything special for larger super cubes. I use a simple threecycle of centers on two adjacent faces. I first place + centers and then x centers. It may seem like you can get a "parity" in the + centers on the last two faces where only two centers need to be swapped. If you just turn one of the unsolved center faces a quarter turn and replace centers the parity will be fixed. Solving the "ring" cubes like 3.1.12 and 3.1.14 actually seem easier because there aren't any hidden stickers.

Especially 1098 moves for 2.1.1. Did you pair most of the edges and corners near the beginning? Because that's the only way I can think of to achieve such a move count. I toyed with the idea of F2Lstyle solving of the corners and edges but found it too hard so gave up. After one failure, I managed to solve 3.4.11 using reduction. The first time I wasn't careful enough near the beginning and suddenly noticed the blue and green centers adjacent to each other after reducing all the edges! [facepalm] But the second time went well. I use conjugates with Skewb moves on the outside for the reduction: 9 move sequences to pair the arrow/2color pieces, 11 moves to join the house shapes to the edges, and 13 moves to join triangles to corners. I hope to get under 400 moves the next time. Work is very busy at the moment and I look forward to having the brain energy to get back to GBing again.

Hey guys, haven't checked in here in a while. Lots of new puzzles and features and it seems I've been blown out of the water by Michael and others. Seeing as I'm still trying to concentrate on school, I won't have much time for puzzles, but I'll try to find some time to fiddle with all the new ones.

Well I gave the corner twisting puzzles a try. I was surprised how easy it was to get to the last layer. I'm not really sure where to go from here though: Attachment:

I've tried a few simple things but I don't see how to make any more progress. I figure I'll use pyraminxlike moves...? EDIT: I ended up solving this pretty easily. If you start with a solved cube there are some short (4 move) sequences to 3cycle edges. Also, if you send an edge piece "around in a circle" along one face it will flip the edge piece orientation.

Alright Julian i admit that without a compleetly unreasonable amount of luck i can't beat that pentultimate reccord however after all that practice i'm sure those super pentultimate and even icosapentultimate reccords can be brought down lower I have also been looking at 2.2.32.2.5 and i have no idea how to orient the centers without messing up the pyraminx crystal edges so any hints regarding that would be much apriciated.
