Brain Test Games

Ten fast, free skill challenges. Daily puzzles. Shareable scores.

Each game is a short, focused test of one piece of your brain or body: how well you estimate time, how steady your hands are, how fast you react, how round you can draw. Every game has a Solo mode for practice, a Daily mode where every player gets the same puzzle, and a Challenge link you can send a friend to race the exact same game.

Closer

Time estimation. Tap when you think 10 seconds has passed.

Eyeball

Visual estimation. Cut a bar in half, make a perfect square.

Brain Glitch

Stroop test. Tap the ink color, not the word.

Round

Draw a circle freehand. Real geometry scores the roundness.

Reflex

Reaction time. Wait for green, ignore the fakes, tap fast.

Steady

Hand stillness. Hold for 7 seconds, we measure every tremor.

Pop

Count estimation. Dots flash for a moment. Guess how many.

Snap

Digit span. A number flashes, type it back, it grows.

Rhythm

Beat keeping. Hear the tempo, then keep it going.

Aim

Target speed. Tap as many targets as you can in 30 seconds.

What are brain test games?

Brain test games are small, focused challenges that isolate one cognitive or motor skill at a time. Unlike long puzzle games, a brain test takes a minute or two and gives you a single readable score you can compare across days. Most of the underlying tasks come from psychology and neuroscience research, where they have been used for decades to measure reaction time, working memory, attention, and motor control. The versions on this page are gamified so they stay short, fun, and competitive.

Playing them daily produces a clean before-and-after of your own state. Your reaction time on a tired morning is meaningfully slower than after coffee. Your hand steadiness changes between calm and stressed. Your number estimation tightens up with practice. Pick three favourites, run them every day, and watch the numbers move.
