Unstable

Unstable is a turn-based puzzle-strategy game where two players fight for control of the board by carefully placing their atoms in order to cause chain reactions and wipe out the other player’s atoms. Full Instructions provided in-game.

Each player (human or computer controlled), in turn, places their atoms in order to take control of the board. Atoms can be placed on empty squares or squares already under your control.

Atoms are made unstable, and will explode, spreading atoms to adjacent squares, when too many atoms are placed on one square. When an atom spreads onto a square with existing atoms, the atom count of that square increases, and the current player becoms owner of those atoms. When atoms spread, they may cause a chain reaction to make other atoms explode. This can lead to a rapid change of control over the board.

After each player has placed their starting atom, the game continues until only one colour of atom remains on the board, and that player is declared the winner.
