Mahjong Firefly

Mahjong Firefly is a well-crafted game of, you guessed it, classic Mahjong. The goal is to find 2 pieces with the same pattern — watch out, since these cannot be blocked by any other pieces, and you won’t be able to connect them. Get rid of all the playing pieces on the board as fast as you can — beware of a few special pieces that will get your pieces shuffled: fireflies. How many levels will you complete before the timer runs out?
