Brain games
Five short games, each testing one thing: how fast you react, how much you can hold in mind for a few seconds, or how closely you notice small differences. Each takes one to three minutes, and all of them work with touch, a mouse or a keyboard.

Before you play
Four of the games get harder every level until your lives run out, so your score is how far you got. The reaction time challenge works differently: five rounds, scored on your middle time, so one lucky or slow tap doesn't decide it.
Your best score is kept in this browser only, so you can try to beat it next time. It is never sent to us, and there are no accounts or leaderboards.
Scores move with sleep, attention, practice and the device you play on, so treat each one as a result for today. The games are for fun. They are not medical or cognitive assessments.
