Crab Mahjong
Crab Mahjong has a domed shell in the middle that rises to four tiles high, and two claws reaching out from each side.
The claws are your friends. They are short and stand apart from the shell, so their tiles come free early and give you partners for tiles in the shell.
How to play
The rules are the same on every layout. Click two free tiles with the same face to remove them. A tile is free when nothing sits on top of it and its left or right side is open. Any flower matches any flower, and any season matches any season. Clear all 72 pairs to win. The how to play guide has pictures.
How the Crab layout is built
The shell is widest across its middle three rows. The claws are short columns at the four corners, with a little more of each claw joined to the shell.
Tips for Crab Mahjong
- Take the highest part of the shell first. It is four high and covers the most tiles.
- Use claw tiles as partners for shell tiles rather than matching claws with claws.
- The rows joining the claws to the shell are the longest on the board. Work them from both ends.

How we rate difficulty. We had the computer play 200 games on each layout, picking moves the same way our Hint button does. On Crab it cleared the board without a shuffle in about 50% of games. That is about the same as the classic Turtle. People who plan ahead do better than that, but the order of the layouts stays much the same. The full list is on the all layouts page.
