100% free Nothing uploaded No sign-up Instant

Test your brain. Beat your best.

Reaction time, memory, aim, the chimp test, Simon, dual N-back, the Stroop test and more — free brain games and cognitive tests that run in your browser. Your scores stay on your device, with no sign-up and nothing uploaded.

Why we're different

Most brain-game sites bury the play button under ads, gate your stats behind a login, or nag you to sign up first. We built the opposite.

No sign-up, ever

No account, no login, no "verify your email" wall before you can play.

100% free

Every game, every mode, with no paid tier and no locked levels.

Nothing uploaded

Your scores stay on your own device — nothing is sent anywhere.

Works offline

Load a game once and it keeps working even with no connection.

Beat your best

Your personal best is kept for each game, so you always have a number to chase.

12 games, no catch

Pick a game and start instantly. All run in your browser, all run for free.

Looking for the typing speed test? It lives on our sister site, Hivly Play — measure your words per minute.

Your scores, and nothing leaves your device.

Plenty of brain-training sites tie your stats to an account, push a subscription, or wrap every game in ads. We took the opposite path: each game runs on your own device, your best scores are kept right here in your browser, and nothing is uploaded.

Measured fairly

Times are taken straight from your browser's high-resolution clock, so a reaction-time or aim score is a real number you can compare with yourself.

Instant, no round-trip

Everything runs the moment you click. No upload queue, no API call, no spinner waiting on a server.

Just for fun

These are casual, informational games to test and train yourself — not medical or diagnostic tools.
