The games

Eight short games, each with its own page, levels and tips. Choose by mood: something to remember, something to look at closely, something to count or something to react to.

Hold it in mind

Something appears and goes away; you bring it back. The pattern, trail or number grows after every round you get right.

Flash GridA few tiles glow and fade; tap the ones you saw.
Light TrailA few panels light up in turn; tap the trail back.
Number SpanWatch a number pass digit by digit, then key it in.

A steady eye

You look closely and ignore what is not asked: the word under the ink, the symbols that match, the item that does not repeat.

Ink & WordTap the colour each word is printed in, whatever it spells.
Odd One OutSomewhere in the grid, one symbol is not quite like the rest.
Step BackDoes this item match the one from a few places back?

Counting

Sixty seconds of sums typed on a keypad, from simple additions to whole-number percentages.

Quick SumsOne minute, a keypad and as many sums as you can solve.

Quick hands

Wait for the signal and tap. Three modes, from a single panel to go-or-stop.

Reaction TimeKeep still until the panel changes, then tap straight away.
