Great puzzle game. Hexagons are flooding the board, your task is to clear them. Connect 4 hexagons, with the same number, to form one new hexagon and make some space. As new hexagons arrive, your space gets tighter.

If you're in trouble, use the 'flash' icon to delete one hexagon that bothers you the most. Beware, it will cost you coins, that you can earn during the play.
Pay attention to the top of the screen - upcoming hexagons are announced there.
