Clonium looks gentle: a tidy grid, some colored dots, players quietly adding one dot per turn. Then somebody's cell hits critical mass, explodes into its neighbors, captures them, sets off three more explosions, and half the board changes owner in a second. That's the entire appeal. This chain-reaction territory game has rules a child could memorize, yet the combinations are effectively endless — every turn is a small bet on which cascade goes off first and who it swallows. Perfect for friends who like their battles calm-looking and quietly ruthless.
Players take turns placing dots into cells of a shared grid.
Corners are gold. A corner cell has only two neighbors, so it overloads at just two dots — cheap to arm, hard to attack. Edges come next, center cells last. In the opening, spread quietly rather than stacking one tall tower: you want several low cells that opponents are scared to touch. And learn the core discipline early — never add a dot to a cell sitting next to an enemy cell that's about to burst, because you're literally loading their explosion with your own pieces.
It works beautifully as a two-player duel and scales up for a small group sharing one device.
Yes — free in your browser, no downloads or sign-ups required.
Most rounds run five to fifteen minutes, with the ending usually arriving in one dramatic burst.
Almost not at all. The board is fully visible with no hidden information, so cascades are calculable — the better planner wins.
Definitely. The rules fit in a sentence, and watching the explosions is half the joy for younger players.
