Reaction Time: 2 Player Games

Who reacts first? Put one phone between you and a friend and find out. This two player reaction game splits the screen 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. The first correct tap wins +1; a tap too early costs −1.

ONE PHONE, TWO RIVALS
• Face-to-face: the far player's half is turned around, so both of you read the same challenge the right way up.
• Fair split-screen touch: each side reads its own button, and a tap counts the moment your finger lands.
• Plays offline: no Wi-Fi, no account, no waiting for an online opponent.
• Blue and Coral, two capybara rivals, mark every win and every tie.

21 MINI-GAMES
Reflexes, sharp eyes, quick math and mazes in short rounds:
Flash point · Ink check · Triple take · Math snap · Mixed six · Capy's orange · Capital call · Hidden zero · Odd mood · Shape crash · Double vision · Bigger crowd · Alphabet scan · Three in line · Plus side · Dice balance · Blue link · Spot the capy · Odd tile · Rogue arrow · Capy count

Spot the capybara among hippos and penguins. Add up the blue and orange dice. Keep counting after the number disappears. Tap when a word names its own ink color. Every rule fits on one line, so new players learn it in seconds.

YOUR RULES
• Quick duel starts a 5-game match in one tap.
• Custom match: pick the mini-games, play 3, 5 or 10 games, and set the pace to Easy, Medium or Hard.
• Pause any time. An unfinished match is saved and waits for you.
• One-tap rematch to settle the score.

SOLO PRACTICE
No rival nearby? Race your own reaction time. Each mistake adds a second, each missed signal adds half a second, so accuracy matters as much as speed. Your stats keep matches played, best reaction, accuracy and correct taps for every mini-game.

ADS AND REMOVE ADS
The game is free to play and shows ads, never during a round. Remove ads is a single one-time purchase, not a subscription, and all 21 mini-games stay unlocked either way.
