All you have to do is press the right button in time. The hard part is working out what the game wants in a split second.
A command flashes on the screen: PRESS IT, DON'T PRESS IT, PRESS THE BIGGEST, WAIT FOR GREEN, PRESS 1 - 2 - 3. Fifteen command types in all: colours, numbers, sizes, positions, a fake button, the odd one out, a Stroop round (a colour word printed in different ink) and a memory round.
New command types unlock as your level grows, while the reaction window shrinks from 2.2 seconds down to 0.7. From level 8 the button colours can swap places right after you have read the command, and from level 10 the buttons start drifting away from your finger.
An unbroken streak earns a flame and a score multiplier: the faster you hit the right button, the more points you get.
Two modes. Endless — one mistake ends the run. 60 seconds — a mistake only breaks your streak, the run lasts until the clock does. Each mode keeps its own best score.
How to play
One control: tap on a phone or click with the mouse.
1. Tap anywhere on the screen to start a run.
2. Read the command at the top and carry it out before the timer bar runs out.
3. Commands vary: press the button, do not press it at all, press it twice, wait for green, pick the right colour, number, size or position, press the fake button, find the odd one out, press three buttons in the order 1 - 2 - 3, or recall the colour shown before the buttons appeared.
4. The faster your correct press, the more points it scores. A clean streak raises the multiplier, a miss resets it.
5. Switch modes with the ENDLESS and 60s buttons at the top left; the note icon on the right toggles sound.
6. In Endless mode you can continue a lost run by watching an ad, up to twice — your score and level are kept.
