Atoms: Chain Reaction

Create chain reactions with your atoms to take over your opponents' squares. Tap to add an atom to either an empty square or one you already own. Fill up a square to make it explode into the neighbouring squares and claim them as your own. Create chain reactions to wipe out your opponents and win the game by exploding every square on the board in one chain reaction. Play with up to 4 players, with friends or against the CPU.

Corner squares can store one atom before adding another makes them explode. Edge squares can store two, and the others can store three.
