Controls
Hold your half of the screen, then tap the instant the signal flashes. Early taps lose the round.
How to play
- Relax your hand — tense fingers react measurably slower.
- Do not watch the screen rhythm; there is none. Watch only for the flash.
- Anticipate with a count that stays flexible, never rigid.
- In two-player mode, keep your tapping finger hovering, not touching.
- Sub-250 milliseconds solo is genuinely elite territory.
About this game
Reflex Duel is pure reaction time wearing a game costume. The screen sits dark and quiet, both players hold their touch zones, and then — after a random delay engineered to defeat anticipation — a signal flashes. The first correct tap wins the round. Tap early and you forfeit it. It is西部拔枪 for thumbs, and it is brutally honest about who reacted faster.
The anti-cheat delay is the heart of the design: the wait is randomised between one and four seconds with no visual rhythm to learn, so twitching early costs the round outright. Ten rounds make a match, complete with round history, false-start penalties and a running score that makes comebacks possible until the very last flash.
In solo mode you duel an AI whose reaction floor tightens from a casual 400 milliseconds down to an inhuman 180 on the hardest tier — around the limit of human perception. Between rounds the game shows your actual reaction time in milliseconds, which quietly turns it into a personal training tool: regular players genuinely watch their average drop over weeks.
Local two-player mode splits the screen into two touch zones, making it the definitive settle-any-argument game. No accounts, no lag, no internet: just the screen, the flash and the truth about your nervous system. Best of ten, false starts punished, ties replayed.
Frequently asked questions

Can I see my reaction times?
Yes, every round reports your time in milliseconds and the match summary shows your average and best.

Ten flashes, with ties replayed. First to win the majority takes the duel.
