Reaction Time Test
A reaction time test measures the gap between a signal and your response — usually a click on colour change — and a typical simple reaction lands around 200-270 ms.
Play freeVisual Memory Test
A visual memory test checks how well you recall patterns, positions, and images. How it works, a quick version to try, and what your result does and doesn't mean.
Play freeNumber Memory Test
A number memory test measures your digit span — how many numbers you can recall in order. The average, what affects it, and how chunking stretches it.
Play freeSequence Memory
Sequence memory tests show a growing pattern of flashing tiles you must repeat back in order — the digital descendant of the old Simon game.
Play freeStroop Test
The Stroop effect is the slowdown you feel when you name the ink colour of a colour word that disagrees with it — like the word 'RED' printed in blue.
Play freeChimp Test
The chimp test flashes numbered squares for a split second, then hides the numbers — you tap them in order from memory, testing fast visuospatial recall.
Play freeN-Back Test
The n-back task asks you to flag when the current item matches the one from N steps back — a demanding test of working-memory updating.
Play freeAim Trainer
Aim trainers and reaction games drill how fast and accurately you can spot a target and click it — sharpening that specific skill, not your general reflexes.
Play freeTyping Speed Test
Typing speed reflects a practised motor skill plus processing speed and attention — measured in words per minute, where 40 wpm is average and 65-plus is fast.
