Rubik's Cubes are loads of fun, but near impossible for puzzle-solvers who can't see the colors that make up each of the sides. So, how do you translate the way the puzzle plays?
Why not print each color in braille on the cubes? Braille Rubik's Cubes do exist, but have an extra layer of confusion for the player. When the player rotates the cubes, the dots change orientation. Orientation is key because it could mean some of the letters could be read upside down.
Brian Doom has created a tactile solution to the Rubik's Cube to let blind people get in on the game. His design is not subtle, with easily recognizable, highly tactile items put in place of the colors — things like screws, felt and the like.
His idea of having items easily recognizable by touch is so that, as players turn the cube, they can feel the result of their moves very quickly from all sides. He calls it the "Doom Cube."
While there are other tactile versions of the Rubik's Cube out there, this one is absolutely straightforward for a blind player. Even better? All the instructions to assemble a Doom Cube are on Doom's website.
Even if the plan is a few years old, it's funky and functional and stands the test of time!
