Obliterate your opponent in a game of skill using the exploding power of ancient crystals.
Each player takes a turn to place a crystal but each tile can only hold so many before it explodes, sending its crystals into the adjacent tiles and claiming them for you:
corner tile = 1 crystal, side tile = 2 crystals, middle tile = 3 crystals
When only your crystals remain on the board you get the sweet, sweet taste of victory.
