Clonium
About Clonium
Clonium is a free two-player browser strategy game where explosive chain reactions let you capture every opponent cell on the board.
Players take turns filling shared board cells until they explode, scattering pieces into adjacent cells and converting any opponent pieces they land on. Simple rules hide deep combinatorial strategy, making Clonium highly replayable.
How to play Clonium
Clonium tasks players with clicking cells to fill them, triggering explosions that scatter pieces and convert opponent territory.

Tips
- Identify one of your own cells on the board and click or tap it to add a piece.
- Watch the cell's capacity — when it holds the maximum number of pieces it explodes automatically.
- Observe the explosion scatter pieces into all adjacent cells, converting any opponent pieces in those cells to your color.
- Plan your next placement to set up chain reactions that sweep through multiple opponent cells in a single turn.
- Continue taking turns until one player controls every remaining cell and wins the game.
Why Clonium stands out
Clonium stands apart from other two-player browser games through four design qualities that turn simple rules into deep tactical play.
- Chain-reaction captures. One well-placed piece can trigger cascading explosions that flip entire regions of the board in a single turn.
- Every cell is a potential weapon. Loaded opponent cells can be turned against them, so board tension builds throughout every game.
- Combinatorial depth from minimal rules. With just one rule — fill, explode, scatter — the number of tactical combinations is effectively endless.
- Instant local two-player sessions. No accounts, no lobbies; two players share one device and alternate turns immediately on any browser.
- Escalating spectacle. As the board fills, explosions grow larger and more frequent, making late-game turns visually dramatic.
