The Bump Cube is a simple 3x3x3 Rubik's cube, but with an interesting twist. It spawned a whole series of puzzles and created a verb of its own.
Invented by Hidetoshi Takeji, Bump Cube is a simple 3x3x3 Rubik's cube, but with an interesting twist. The centres are not centred, but justified to one corner. In doing so, each individual piece is a different shape. As all the cubies are stickered the same, you must solve by shape.
The handmade version attended the design competition during IPP26 in 2006.
Hidetoshi-san met a speed-cuber at a competition in Osaka with interest in his cube. He lent it to him, who showed it to a project group. Rubik's and MegaHouse then mass produced the puzzle starting in autumn of 2008. That mass produced version was named "Rubik's Mirror Blocks".
Other producers also jumped on this variant and endless colour variants have been produced since.
Edge length: 57 mm
Weight: 82 grams
Parallel an even more endless series of puzzles named "Bump ..." appeared on the forum. "Bumping" is today one of the most often employed methods to make a shape variant, reserved for puzzle where the axis system is moved inside the solid without being reoriented.
