3D Mahjong
The tiles are stacked into a block, five by five by four in the middle size, and the block turns. Drag it with the mouse or a finger, or use the two arrow buttons for a quarter turn. A tile can be taken when it has at least two open sides that meet at a corner: the top and one side, or two neighbouring sides, or three sides. A tile with only its front face showing is stuck.
So the game starts at the edges and corners. The rim of the top layer is free, and so are the four vertical edges of the block, all the way down. The faces of the cube open as you cut into them, and the middle is reached last. Turning the block is not decoration: half of the free tiles are on the side you are not looking at, and the pairs-open counter under the cube counts all of them, so if it says four and you see one, turn.
The deal is built backwards, the same way as on the flat boards, by lifting free pairs off a full block in a random order and writing matching faces into their places. The order it was lifted in is a solution. The shuffle re-deals the tiles that are left into their present places by the same method, so it never produces a dead board unless the remaining tiles are physically walled in.
Sizes: 4×4×3 with 48 tiles, 5×5×4 with 100, and 6×6×4 with the full 144. The blocked-tile switch under the board greys out anything you cannot take yet, which on a cube is most of it. This is a browser drawing a few hundred boxes in three dimensions; on an older phone the large block will be slow, and the small one is the one to pick there.
