Every game in Brain & reflex tests
- Reflex Test — Wait for green… TAP! Measure your reaction time in milliseconds and beat your average over 5 rounds.
- Typing Test — 60 seconds, common words, live stats. Get your WPM and accuracy — then beat them.
- Aim Trainer — 30 seconds of targets. Hits, accuracy and speed — the warm-up FPS players swear by.
- Sequence Memory — Watch the tiles light up, repeat the pattern, go one further. Your memory taps out eventually…
- Number Memory — A number flashes, then vanishes. Type it back — every level adds a digit.
- CPS Test — How many clicks per second can you do? Pick 5, 10 or 30 seconds and find your rank.
- Chimp Test — Numbers appear on a grid, then vanish the instant you tap 1. Keep tapping in order from memory — one more number every board.
- Visual Memory — Squares flash white, then vanish. Tap every one of them back — each level adds a square and the grid keeps growing.
- Verbal Memory — One word at a time: seen it already, or is it new? Easy for ten words, brutal by fifty. Three lives.
- Mental Math — Add, subtract, multiply, divide against the clock. Answers submit themselves — 60 and 120 second drills, scored separately.
- Color Test — One tile is a slightly different shade. Tap it. The grid grows and the difference shrinks until you can't see it any more.
- Emoji Memory — One emoji at a time — seen it already this run, or is it new? Pictures stick better than words, so scores run high.
- Stroop Test — The word says BLUE, the ink is red. Answer the ink. Ninety years of psychology says you'll hesitate.
- Memory Match — Sixteen cards, eight pairs, one clock. The classic pairs game, ranked on how fast you clear it.
- Number Rush — Find 1 to 25 in order, as fast as you can. Stare at the middle — your eyes are slower than you think.
Questions
Are these tests accurate?
They measure what a browser can measure. Reaction time includes your screen and input latency, so compare runs on the same device rather than against a lab figure.
What is a good reaction time?
Most people average 200–250 ms on a visual test. Under 200 ms is fast; the Reflex Test grades each run so you can see where you land.
Do I need an account?
No. Your best scores are stored in this browser only — nothing is uploaded and there is nothing to sign up for.
Do they work on a phone?
Yes. Every test is built for one-handed touch first and keyboard second.
