Is every Mahjong Solitaire game winnable?

This is one of the most important questions in the game. The honest answer is that it depends on how the board is made, and we make ours the fair way.

Quick answer: A truly random pile of tiles is not always solvable, but on Mahjong.now every layout is. We build each board by placing tiles in a valid, solvable order, so a winning path always exists. It is up to you to find it, and Shuffle and Hint are there if you get stuck.

Random deals can be dead on arrival

If you just scatter 144 tiles into a shape at random, some of those boards are impossible to finish no matter how well you play. A needed tile can end up trapped in a way that no order of moves can free. Many older mahjong programs did exactly this, which is why players sometimes hit a wall through no fault of their own.

How we guarantee a solution

Mahjong.now generates every board differently. We place the tiles in an order that is known to be solvable from the start, so a full winning path always exists. You can still lose by making the wrong moves, but you will never be handed a board that is impossible.

Solvable is not the same as easy

A guaranteed solution does not mean a guaranteed win. You can still paint yourself into a corner by removing the wrong pairs. When that happens you have not lost forever: use Shuffle to rearrange the stuck tiles, or a hint to find a legal pair.

What is a dead board in Mahjong?

A dead board is a gridlock. Tiles are still on the board, but no two free tiles match, so there is no legal move left. It usually happens after removing pairs in a bad order. On Mahjong.now you can Shuffle the tiles or Undo to escape it, since every board is solvable.

Can you shuffle tiles in Mahjong Solitaire?

Yes. Shuffle takes the tiles still left on the board and rearranges them into a new pattern, which is a lifesaver when you hit a gridlock. It reopens matches so a stuck board does not have to end your game. On Mahjong.now the reshuffled board stays solvable.

What happens when you run out of moves?

If no two free tiles match, you are stuck, and tiles are still on the board, which we call a dead board. Since every Mahjong.now layout is solvable, being stuck means an earlier choice went wrong. You can Undo to rewind, or Shuffle to rearrange the leftover tiles and reopen a path.

How do you win at Mahjong Solitaire?

You win by removing all 144 tiles, every last pair. The way to do it consistently is to open the tallest, most-covered stacks first, uncover buried tiles as early as you can, and think one or two pairs ahead so you never trap a tile you still need.
