About this game
How fast are you, really?
The moment red turns green — how many milliseconds does it take you to react? Reflex Battle is a collection of 5 quick tests for your reflexes and short-term memory. Each round takes seconds, and you'll want "just one more" every time.
⚡ Reaction Time — tap the instant it turns green. A battle measured in milliseconds.
🔢 Number Memory — memorize where the numbers are, then tap them in order.
🎵 Sequence — repeat a flashing pattern that grows longer each round.
👆 Tap Speed — how many taps can you land in 5 seconds?
⏱ Time Sense — stop at exactly 5.00 seconds, with the timer hidden.
See your percentile instantly
When a test ends, you get your score, a "Top X%" rank, and a fun grade — from Superhuman to Half-asleep.
Summon a friend with a challenge card
Turn your result into a shareable image card and dare a friend: "Can you beat this?" They take the challenge, and the rivalry begins.
Runs fully offline with no server, and collects no personal data beyond advertising.
★ Just for fun — not a medical or scientific measurement, and the "Top %" figures are approximate.
Recommended for
- Anyone who loves quick reflex and brain mini-games
- Friends and family who want a reaction-speed showdown
- Score-chasers who go "one more time" in spare moments
