Mirror Blocks

Unlike a standard Rubik's Cube, solvers must align the pieces by their varying geometric dimensions rather than by color. The puzzle features uniform sticker colors—often silver or gold—meaning you must rely entirely on shape and size.

The Mirror Blocks puzzle was created by Hidetoshi Takeji. It mechanically functions like a standard 3x3 twisty puzzle but completely changes the solving logic through its shape-shifting pieces.

No, the colors do not matter because the puzzle typically features uniform silver or gold stickers. You solve the puzzle by matching the varying physical dimensions and shapes of the blocks instead.

While it shares the exact same internal mechanical structure as a standard 3x3, many find it more disorienting. Because the pieces shape-shift as they turn, it requires a strong reliance on tactile feeling and size recognition rather than color matching.
