Dyscalculia is a numerical translucent three layer slide puzzle with a twist. You can move the tiles in the traditional left, right, up, and down, and also push columns from above and below to intermix the three layers. But there's an additional move unique to this puzzle: the middle layer can be rotated. Once you've shuffled the puzzle, try to restore each numbered tile to its starting position.
