Chain Reaction King for iPhone

Game overview

Chain Reaction King is a competitive, turn-based orb strategy game in which players try to be the last one with orbs on the board. Each participant takes turns placing or reinforcing orbs in cells; when a cell's orb count exceeds its stability threshold it explodes, distributing orbs to adjacent spaces and potentially taking over enemy positions.

Core mechanics

The game revolves around predictable chain reactions and positional play.

• Cells explode when their orb count passes the cell’s reactive threshold, sending orbs to neighboring cells and triggering further reactions.
• You place orbs on your turn by selecting either an empty cell or a cell that already contains your orbs.
• Explosions can convert adjacent enemy-held cells, letting you seize opponents’ pieces during a cascade.
• Matches support 2 up to 8 players, each acting in rotation until only one player remains.

Play options

Choose how you want to play — solo, local, or online.

• Face the computer in single-player matches to practice tactics and timing.
• Play with friends in pass-and-play or on the same device for local multiplayer rounds.
• Join global lobbies or online rooms to compete against players around the world.

What players enjoy

Reasons the game appeals to strategy fans:

• The need to plan sequences several moves ahead makes each decision meaningful.
• Quick, dramatic chain reactions create tense turning points and comeback opportunities.
• Simple rules hide deep strategic possibilities, rewarding clever positioning and timing.
