📖 About Clonium

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.

🎮 How to Play

Players take turns placing dots into cells of a shared grid.

  1. Claim a Cell — On your turn, add one dot to an empty cell or to a cell you already own
  2. Respect the Limit — Each cell holds as many dots as it has neighbors before it goes critical
  3. Trigger Explosions — An overloaded cell bursts, sending a dot into every adjacent cell and capturing them
  4. Ride the Chain — Captured cells that also overload explode in turn, cascading across the board
  5. Take Everything — When only your color remains on the grid, the board is yours

✨ Game Features

  • One-Move-Per-Turn Simplicity — The whole game is "click a cell"; the depth is in what happens next
  • Spectacular Chain Reactions — A single well-placed dot can flip the entire board
  • Local Multiplayer — Pass one device around and battle friends on the same grid
  • Fast, Tense Rounds — Games build from quiet openings to explosive endings in minutes
  • Endless Variety — No fixed solutions; every board state is its own small puzzle
  • Easy for Anyone to Join — Spectators understand what's happening within one cascade

👥 Tips for Playing with Friends

  • Two players is the purest duel, but a full table of friends makes the politics half the fun — agree on whether "ganging up" is allowed before it happens
  • Don't celebrate a big explosion too early; experienced friends will make you regret the board you left behind
  • Play a couple of teaching games where everyone explains their move out loud
  • Rematches are mandatory etiquette — Clonium losses always feel one move away from revenge
  • Short on time? A smaller grid keeps the same tension in a faster game

🎯 Strategy Guide for Clonium

Getting Started

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.

Advanced Tips

  • Build Fuses — Line up your cells so one explosion feeds the next, creating a cascade your opponent can't interrupt
  • Count the Criticals — Before every move, check which enemy cells are one dot from bursting and what they'd capture
  • Let Them Overextend — A rival spreading thin leaves unstable cells everywhere; be the one who sets them off
  • Defend by Proximity — Owning the cells around your big stacks means enemy explosions capture less
  • Time the Detonation — The player who triggers the first giant chain often loses it; the one who answers it usually wins

Common Mistakes to Avoid

  • Feeding Enemy Bombs — Adding dots beside an opponent's near-critical cell donates your pieces to their chain
  • Stacking the Center Early — High-limit center cells eat many dots and repay them slowly
  • Triggering Your Own Trap — Exploding too soon scatters your cells into enemy reach
  • Ignoring Corners — Whoever owns the corners owns the most stable territory on the board
  • Playing Move to Move — Clonium punishes local thinking; every dot should serve a chain you're planning
