Amazon App Store – Free Android App Of The Day – 4 Player Reactor


4 Player Reactor is an entertaining, multi-player, split-screen game. This simple puzzle game supports 2 – 4 players so it makes for a great party game. Or, hone your skills using single-player practice games.

The premise of the game is simple: solve a puzzle and be the fastest person to tap in. Puzzles range from identifying shapes or colors to easy math equations. Each player gets an assigned tap area and must focus on the center of the screen. Have the quickest reaction time when the correct solution is visible!


The app includes 22 different puzzle modes and is a cinch to customize. Like or dislike a particular puzzle? Enable or disable it in the custom menu. Choose from 4 different difficulty levels: easy, medium, hard, and insane. Select how many correct hits should happen before the puzzle mode changes. You can also opt to play the games in a random order or play modes that are easier to win more often. A clever Adaptive Mode makes it harder to hit the button for a player that’s far ahead in points. The required number of points per round can be set from 1 to one million.
