Reaction Time: 2 Player Games

Get it on Google Play

What it does

Put one phone between you and a friend. The screen splits in half: each rival gets a side, a big tap button and a mirrored copy of the challenge. Tap only when the rule is true, and the first correct tap scores. It plays offline, with no account.

Highlights

  • One phone, two rivals: face-to-face split screen, with the far half turned around
  • 20+ mini games: reflexes, sharp eyes, quick math and mazes, each with a one-line rule
  • Play duel: a 5-game match in one tap, or build your own with 3, 5 or 10 games and Easy, Medium or Hard pace
  • Pause and resume: an unfinished match is saved
  • One-tap rematch to settle the score
  • Solo practice: race your own reaction time and track stats per mini game
  • Light and dark themes, with haptics and sounds you can switch off

Made for

  • Friends, roommates or couples who want a quick offline game
  • Waiting rooms, trips and anywhere without Wi-Fi
  • Anyone who wants to test and improve their reaction time

Frequently asked questions

How many players can play?
Two players share one phone in a split-screen duel, or one player can practice solo.
Does it need internet?
No. Matches and solo practice work offline.
How does scoring work?
Tap only when the rule is true. The first correct tap wins plus one point, and a tap too early costs minus one.
Can I choose the mini games and difficulty?
Yes. Play duel starts a 5-game match in one tap, and a custom match lets you pick the mini games, play 3, 5 or 10 games and set the pace to Easy, Medium or Hard.
Is the game free? Are there ads?
The game is free to play, with ads between matches and never during a round. Fourteen mini games are always free. The Brain pack adds seven games: watch a video ad for temporary access, or unlock every game and remove ads with Reactor Pro, a one-time purchase rather than a subscription.
Is there a solo mode?
Yes. Solo practice races your own reaction time, where each mistake adds a second and each missed signal adds half a second. Stats track matches played, best reaction, accuracy and correct taps for every mini game.
