Chain Reaction is an explosive turn-based strategy game of area control. The rules take seconds to learn but the tactics run deep: place your orbs, push cells past their limit, and unleash cascading chain reactions that flip your opponent's territory in a single, satisfying blast.
HOW TO PLAY
• Tap a cell to add an orb. You can only place on empty cells or ones you already own.
• When a cell reaches critical mass it explodes into its neighbours.
• Those neighbours are captured — and if they overflow too, the reaction chains onward.
• Wipe every opponent off the board to win.
FEATURES
• Local multiplayer for 2–8 players — pass-and-play on a single device.
• Three AI difficulties — Easy, Medium, and a Hard opponent that thinks ahead.
• Custom boards — pick your grid size for quick duels or epic battles.
• Make it yours — choose each player's colour and name.
• Move preview — press and hold any cell to see the full chain reaction before you commit.
• Undo — take back a move while you learn.
• Themes — Classic, Neon, Sunset and Forest, in light or dark.
• Stats & achievements — track your longest chains, biggest captures and victories.
• Shareable GIF replays — export a highlight of your match and share it anywhere.
