Who reacts first?
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
17 lightning-fast minigames for reaction duels – solo vs. bots or online with friends. New: action & recognition games. Who reacts first?
Reactor Party is the reaction duel for iPhone and iPad: a stimulus appears, one clear rule applies – and only whoever taps first and correctly takes the points. One rule, one button, no second chance.
HOW TO PLAY
Every round shows a stimulus – a colour word, a country outline, tumbling dice. Exactly one "tap" rule applies. The moment someone taps, the round is over for everyone.
• Right & first: +100 points, including your reaction time in milliseconds
• Wrong tap: −50 points – and the round still ends
• Some rounds are traps: holding back can win
10 MINI-GAMES
From pure reaction to brain work:
• Word & Colour
• Outline & Country
• Compare population & area
• Dice Balance
• Mental Maths
• Symbol Pair
• Flag & Country
• Flash Count
• Pure Reaction
AGAINST BOTS OR ONLINE
• 1–3 bots in three difficulties – from easy-going to merciless
• Online duel for 2–4 players: quick match or a private room with a 4-digit code
• Game Center leaderboard for your online wins
FAIR BY DESIGN
Online, your local reaction time decides – not whose internet is faster. A better connection gives no advantage.
ALSO ON BOARD
• 6 languages, switchable live
• Detailed statistics: hits, misfires, best & average reaction time
• Crisp haptics and sound
• No account needed – your progress stays local on your device
