Mahjong Firefly is a free online mahjong game where you clear the tiles to progress through the levels. There is a time limit to get through levels, but special tiles will award you with more time. Advance through the levels and build up your score as you clear boards. Play until you either run out of time, or run out of moves in a puzzle.
Slide numbered tiles on the 4x4 grid and match two like numbers to combine them, trying to create a 2048 point tile.
