Mahjong Solitaire Blast

Mahjong Solitaire Blast is a game for the attentive, patient and diligent. Your task is to find a pair for a bone with some kind of image. When a pair is found, the bones burn out, but new ones open in their place, because they are placed in several balls. Only the outermost exposed bones can be selected. Those in the middle of the row will not be available. It is necessary to be extremely careful, because the borders of the balls are barely noticeable, and the same bones are often located at different ends.
