How does your brain rank?
18 reaction, memory, and focus tests. No login, 30 seconds each — and every result graphs you against everyone else who's played.
Green Light
Wait for the screen to turn green, then tap as fast as you can. Five rounds, your reaction time in milliseconds — and where your reflexes rank against everyone.
Swat
Thirty mosquitoes, one at a time, fast as you can tap. We clock your average time per swat to the millisecond. How quick is your aim, really?
Total Recall
A number flashes, then vanishes — type it back. Each round adds a digit. How long a number can your brain actually hold? Most people cap at a phone number.
Déjà Vu
Words appear one by one — tap SEEN if it's come up before, NEW if it hasn't. Three lives. How far can your recognition memory stretch before it cracks?
Mind Grid
A pattern of tiles lights up, then disappears — tap the ones you remember. Clear a level and the grid grows. How big a pattern can your brain hold?
Chimp Champ
Numbers flash on a grid, then blank out — tap them in order from memory. A chimp named Ayumu beats most humans at this. Are you smarter than a chimp?
Snap
A coloured dot flashes — tap the matching box as fast as you can. Reaction plus a split-second decision. How quick can your brain actually choose?
Ear Drop
Tap the instant you hear the beep — no visual cue, just sound. Five rounds of pure audio reflex. How fast are your ears? Headphones on.
Hold It
Tap on green, but freeze on red — do nothing. The hard part isn't tapping, it's not tapping. Twenty trials of pure impulse control.
Crowd Control
Tap the way the middle arrow points and ignore the four around it. When the crowd disagrees, your brain fights itself. A 30-second focus blitz.
Side Eye
Stare at the centre — a dot blinks in the corner of your eye. Tap where it flashed. The dots drift further out and faster each level. How wide is your vision?
Sequence
Watch the pads light up, then play the pattern back. It grows by one every round — one wrong tap ends it. The classic memory game.
Flash Count
A cloud of dots flashes for half a second — how many were there? Past four, your brain stops counting and starts guessing. Ten rounds.
Join the Dots
Fourteen numbers scattered everywhere — connect them 1, 2, 3, all the way up, as fast as you can. A pure test of visual search and sequencing speed.
Pattern Prophet
Each grid hides a rule — work out what belongs in the empty square. Twelve puzzles of pure visual logic, no words or maths. Can you see the pattern?
Hot Keys
Type the passage as fast and clean as you can. The clock starts on your first keystroke; we report your net words per minute. Best on a keyboard.
Did Something Change?
Two grids flicker with a blink between them. One tile keeps changing colour — but the blink hides it in plain sight. Can you beat change blindness?
Tap Tempo
Listen to four beats, then keep the tempo going on your own — no metronome to lean on. We measure how steady you held it. How good is your internal clock?
