Atom Supremacy

Easy at first glance. Deeply strategic once the atoms become unstable.

Atom Supremacy is a turn-based strategy game built around simple moves and explosive chain reactions. Place electrons on the board, build up your atoms, and push them beyond their limits to capture neighboring cells.

The rules are easy to understand—but every move can transform the entire board. A carefully prepared chain reaction may overwhelm your opponent, while one poorly timed move can turn your advantage against you.

Choose how you play:

• Challenge the computer across three difficulty levels
• Play face-to-face with a friend on the same device
• Select a board size from 3 × 3 to 10 × 10
• Create powerful chain reactions
• Capture your opponent’s atoms and control the board
• Develop new tactics with every match


Small boards deliver fast, intense battles. Larger boards give you more space to plan, build traps, and prepare devastating combinations.

Whether you want a quick match or a demanding strategic contest, Unstable Atom tests your timing, foresight, and ability to adapt.

Online multiplayer is planned for a future update.

The board is ready. Make your move—and start the reaction.
