A REACTION TIME GAME
Flash is a reaction time game with a catch. First you see your target, say a blue star. The card stays grey, then something pops up, and you tap only if it is your target.
Four quick games where right and fast both score. Each round takes a few seconds, and the next one comes straight away.
They start easy and get quicker the more you get right: decoys that look like the target, rules that switch, sums that are nearly right, numbers printed to fool you.

A COLOUR AND SHAPE SORTING GAME
Sort is a quick sorting game. Each card tells you the rule, sort by colour or sort by shape, and you swipe it to the side that matches.
A QUICK MENTAL MATHS GAME
Tally is a fast mental maths game. A sum appears with its answer already filled in, and you decide whether it is true or false: tick or cross.
A NUMBER COMPARISON GAME
Bigger is a number comparison game. Two numbers appear side by side and you tap the one with the larger value.
Flash. You see a target, wait, and tap the instant it appears, while holding back on decoys.
