Butterfly Mahjong

Butterfly Mahjong is Mahjong Solitaire laid out as a butterfly: two wide wings on either side and a raised body of stacked tiles down the middle, 100 tiles in all. The wings open up quickly; the body, three layers high, is where the board is won or lost.

Take free tiles off in matching pairs until none are left. A tile is free when nothing lies on it and its left or right side is open; any season matches any season and any flower any flower. Every board is dealt so it can be cleared, and a hint, three undos and two shuffles help when you are stuck. Pairs that use a tile the last pair just freed build a chain worth more points. Want another shape? Try the turtle or the pyramid.
