27 arenas. Here is what each one asks of you.
Short, timed challenges. Each game explains its own rules and difficulty. Tap any one to see it.
PVT Blitz
speed · 45s
A dot appears at random. Tap the instant you see it — nothing else.
Lights Out
speed · 60s
Five red lights come on, hold, and go out together. Tap the instant they do — anywhere.
Stroop Chaos
attention · 45s
The word says GREEN, the ink is red. Answer the ink, not the word.

Corsi Constellation
memory · 45s

Card Shift
flexibility · 45s
Sort cards by a rule nobody tells you — and that changes without warning.
Pitch Patrol
hearing · 45s
Hear two tones and choose the higher one. The gap stays fixed for the round and can change next round.
Rhythm Echo
hearing · 50s
A rhythm plays. Tap it back — the pattern, not the speed.
Scan Sweep
perception · 45s
Numbers are scattered across the field. Tap them in the requested order before the clock runs out.
Wide Angle
perception · 50s
Something flashes at the edge while you hold your eyes on the centre. Where was it?
Rotation Forge
reasoning · 45s
The same shape, turned. Is it the shape you were shown, or its mirror?
Blink Spot
perception · 50s
A scene flickers between two versions. Find and tap the thing that changes.
Digit Symbol Sprint

Bills, discounts and GST, in your head, against a clock.
Orbit Tracker

Several dots start marked, then all of them move. Point out the marked ones.
Errand Runner
memory · 60s
A list of things to do later — and remembering to do them when the moment arrives.
Sonic Arrows
hearing · 45s
Two tones sweep up or down. Which way did the second one go?
Echo Vault
memory · 60s
Hear a sequence of digits and enter it back. Its length stays fixed for the round and can change next round.
Compass Rose
reasoning · 50s
You face one way, the map faces another. Which way do you turn?
Split Ears
hearing · 50s
Both ears get a count at once. Report the ear you were told to follow. Headphones needed.
Mood Radar
social · 45s
A face, briefly. Which expression was it?

planning · 120s
Move the discs to the target shape in as few moves as you can plan.
