HOW TO PLAY
Take turns placing an orb in an empty cell or in one of your own. A cell explodes when it gets full: 2 orbs in a corner, 3 on an edge, 4 in the middle. The explosion sends an orb into each neighboring cell and turns those cells your color. One move can start a chain across the whole board. Lose all your orbs and you're out.
MAKE IT YOURS
• Three themes: Classic, Ocean and Neon
• A colorblind-friendly palette and a flat or 3D grid
• Choose each player's orb color and sounds
• Turn vibration on or off
• Made for phones and tablets
Chain Reaction is free to play with ads. A one-time Remove Ads purchase turns them off.
What’s new
Chain Reaction has a brand-new look! Glossy glowing orbs, sparks on every explosion, a chain counter, a fresh menu and a new Settings screen. Prefer the original game screen? Settings > Look > Classic. On a slower phone, Effects > Reduced keeps it light (Auto picks for you). Also fixed: a rare crash with banner ads, a freeze when opening a game right after launch, and a game reset after two quick screen changes.
