Read full description

Build critical mass. Trigger explosive chain reactions. Capture the entire board. Chain Reaction OG is a fast-paced local multiplayer strategy game for 2–8 players. Place your atoms, take control of the arena, and unleash powerful cascades that can transform the board in a single move. Every turn matters. Protect your territory, control valuable corners and edges, and wait for the perfect moment to start an unstoppable chain reaction. The rules are simple, but mastering the board takes clever planning, timing, and tactical thinking. # LOCAL MULTIPLAYER FOR 2–8 PLAYERS Gather friends and family for competitive pass-and-play matches on one device. No accounts, complicated setup, or lengthy tutorials—choose your players, select an arena, and start playing. # SIMPLE TO LEARN, HARD TO MASTER Place atoms inside your cells to build critical mass. When a cell reaches its limit, it explodes and spreads atoms into neighboring spaces. Capture rival cells, create massive combos, and eliminate every opponent to become the last player standing. One carefully planned move can trigger a board-clearing chain reaction. # CUSTOMIZE EVERY MATCH • Local pass-and-play multiplayer for 2–8 players • Fast, competitive strategy matches • Four board sizes: Small, Medium, Large, and Huge • Multiple orb finishes and arena styles • Smooth animations and satisfying chain reactions • Responsive, easy-to-use controls • No account required Whether you are looking for a quick two-player battle, a family party game, or an intense multiplayer strategy challenge, Chain Reaction OG makes every match unpredictable. # FREE TO PLAY Play Chain Reaction OG for free.
