How it works

Three moves, one hit of dopamine.

1

Start a challenge

The rule appears, you tap when you're ready. “TAP TO START” — and you're off.

2

Ten seconds of pure focus

Things drop, flash and swap. Only one answer counts: the right one.

3

Rack up the XP

Every win pushes your rank up. Missed it? Go again — the challenge changes, your resolve doesn't.

The mini-games

Ten ways to catch you out.

Every challenge draws a mini-game at random. No chance to switch to autopilot.

Count

Items fall, mixed in with decoys. Count only the right ones.

Appearance

They appear, they vanish, faster and faster. Keep an exact count.

Tracking

A golden disc blends in with the others. Don't take your eyes off it.

Memory

Memorise the cards in a few seconds, then find every pair.

Calculation

Numbers scroll past one by one, with + or −. Work it out in your head.

Clicker

Tap the right items on the fly — and whatever you do, don't hit the decoys.

Order

Numbers and letters mixed together (A = 1 … Z = 26). Sort them. Three mistakes and it's over.

True / False

Statements scroll past — sums, comparisons. Answer true or false, as fast as you can.

Sequence

Tiles light up in an order. Memorise it, then repeat the sequence. One mistake: over.

Perfect Tube

The tube fills up: stop it dead inside the zone. Aim for the golden core for the rare version!

4 tiers Easy Normal Hard Extreme

The difficulty climbs with you: pace, quantities and swaps get tougher tier by tier.

Duel

Same challenge, same second. Fastest mind wins.

Find an opponent in seconds, or challenge a friend directly.
