Well... I was busy during my birthday doing this 6-tile magic after being inspired by Mark's 8-tile hybrid magic.
I present the Magic Ultimaze!

(it has two
double flat single closed loop solutions, two cubic single closed loop solutions, plus a bonus fifth solution made of two closed loops!)

Now imagine using such hybrid techniques on 3x3x3 cubes too, to give them multiple solutions!
