Mahjong Solitaire: which pair to clear first
Any two matching free tiles can go. Choosing the right two is the whole game.

In Mahjong Solitaire you clear the board two tiles at a time. The two tiles must match, and both must be free. A tile is free when no tile lies on top of it and its left or right side is open.

Five habits
- Clear tall stacks early. Every tile under a stack stays locked until the stack comes down.
- Open long rows. A long row frees tiles only from its ends, so it takes many moves to clear. Start on it early.
- With three of a kind free, choose. Clear the pair that frees more tiles, and keep the third for later.
- With all four free, clear both pairs. There is nothing to gain by waiting.
- Don’t clear a pair just because you can. Look for the move that opens something new.
If no matches are left, the game tells you and offers a way to keep going.
