Press or Not

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.
