Tintsnap

Tintsnap is a fast game of split-second color decisions built on a simple, deceptively tricky idea: a stimulus flashes up, and you have a heartbeat to decide whether it matches — then tap yes or no before the clock runs out. The catch is your brain fighting itself: a word might read "RED" while it's painted blue, and telling the two apart at speed is harder than it sounds.

The rules stay simple but the pace does not. Answer right and you score and move straight to the next; answer wrong, or let the timer beat you, and the run bites back — and the time you get per call keeps shrinking the longer you last. A timed mode chases the most correct calls in sixty seconds, a survival mode ends at your first slip, and a speed ladder squeezes the clock tighter with every answer until your nerve gives out. Each mode keeps its own best, along with your accuracy and average decision speed, so you can watch yourself get genuinely quicker.

A bold, color-forward look gives Tintsnap its own strong identity, and a color-blind-friendly word mode keeps it fair for everyone rather than resting on telling near shades apart. Clean, direct, and all about that one snap judgement.

Everything runs on your device: no account, no connection, no ads. Just the call, the clock, and how fast your eyes and brain agree.
