Seven cubes (and one hole) in a frame. The cubes change orientation while being moved.
This puzzle is a successor to Bram's Black Hole puzzle, that was also designed by Oskar van Deventer after an idea of Bram Cohan.
Summer 2009, Bram suggested a variation that has even less cubes, but which may be equally difficult to solve. Because of its shape Oskar called it "Bram's Rocket". Bram's Rocket has seven cubes that move around in a frame. Like any combinatorial puzzle, the object is to scramble the puzzle and then solve it by getting the colours right again. As the paths of the cubes are curved, the cubes change orientation while moving. So the cubes not only have to come to their original position, but they have to come to their original orientation as well. This makes the puzzle very confusing.
Edge length: 21 mm (one cubie)
