Frozen Mahjong

Everything is frozen, can you unfreeze the mahjong tiles? Combine two of the same unfrozen tiles to remove the tiles and unfreeze other tiles.

1. 1

   A tile is FREE if nothing is on top of it and nothing blocks it on the left or right.

2. 2

   Find two FREE tiles showing the same picture.

3. 3

   Click one, then click the other - both disappear.

4. 4

   The tiles that were covering them now become free.

5. 5

   Keep going until the table is empty. Never get stuck - the layouts are solvable!
