Mahjong
Mahjong solitaire: the tiles of mahjong laid out in layers, cleared two at a time - two that match and are both free. A game to yourself, quiet and absorbing, on five layouts of our own.
Playing
Clear the tiles two at a time: two that match - the same tile, or any two flowers, or any two seasons - and both free, with nothing on them and open on their left or their right. Tiles under others show as those on them go.
- Five layouts of our own: Terrace, Twin Peaks and Lantern of the whole set of 144 tiles, and Garden and Tower of half of it, for a shorter game.
- Every deal can be cleared: each is made by taking the layout apart a free pair at a time, and giving each pair matching tiles.
- Drag a tile onto its partner, or click one and then the other; take a move back whenever you like. When no pair is left, Shuffle deals the tiles still there again, so that they can all be cleared.
- A small number or letter in each tile's corner for anybody new to mahjong's characters, and the tiles as large or as small as you want them.
- Your games kept to carry on later; any deal played again by its reference; and a game for visitors to try.
- Leaders boards in each room, and one deal for everybody - a duplicate deal, everybody playing the same tiles - with the computer's own go first as a benchmark if its maker wants.
How our computer player thinks
The computer sees only what you see: the tiles face up, never those still hidden under others.
- A pair it can always clear safely - every tile of its kind free and in view - it clears first.
- Otherwise it deals the hidden tiles out a dozen ways that fit what it can see, and solves each one as if every tile were in view, searching thousands of positions a way. It then clears the pair that leads to a cleared board in the most of them.
- Ask for a hint and it says which pair, and why; hand it the game and it plays on until you stop it. A game it moves in counts on no leaders board.
Its thinking runs in your own browser, in WebAssembly, on as many of its cores as it may use.
