About Brain Reactor
Big laughs. Quick reactions. One device. Brain Reactor turns your iPhone or iPad into a party table for 2, 3 or 4 players. Face your friends, watch the same challenge and race to tap your button at the right moment. A correct answer earns a point. A mistake costs one. Who will react first? BUILD YOUR MATCH Choose your games with clear, colorful icons. Pick random rounds or play in order, set the number of rounds and decide how many correct answers finish each round. QUICK GAMES, DIFFERENT SKILLS Spot the bitten apple, solve an equation, judge overlapping shapes or time your tap when a car appears. The full collection also includes memory grids, dice totals, rock paper scissors, a rotating pointer, dominoes and more. MADE TO PLAY TOGETHER One shared field, large player buttons and instructions facing both sides keep everyone in the game. Play locally on the same device — no app account or online opponent required. YOUR SCREEN, YOUR STYLE Choose Light, Dark or Auto appearance across the entire game. Responsive layouts adapt to iPhone, iPhone Duo and iPad, and resizing pauses the match so you can get comfortable before continuing. 10 GAMES INCLUDED. 20 WITH FULL GAME. Start with the original ten games. The optional Brain Reactor Full Game purchase permanently unlocks the ten additional games and removes between-match ads. It is a one-time purchase, not a subscription. Purchases can be restored from the Full Game screen. Pick your games. Gather your friends. One more round?
