Shapes one by one: seen before, or new? Works in any language.
Seen this shape before, or new?
About 60 seconds. Not medical advice. Stop if you feel dizzy, nauseous or strained.
Shapes appear one at a time. For each one, answer SEEN if it already appeared in this level, or NEW if not. Click the buttons, or press S / N (or ← / →). 7 levels of 12 shapes: level 1 uses 4 kinds of shape in one colour; each level adds shapes, then colours, then outlines, so look-alikes get closer (16 shapes, 6 colours, filled or outline by level 7). 3 mistakes end the test.
This is a recognition memory test. It uses shapes instead of words, so it works in any language. A quick measure of how you did on this test today, on this device. Practice makes you better at the test itself; it is not a medical or IQ test.
Not medical advice. Stop if you feel dizzy, nauseous or strained.
Remember the gold balls, then follow them as they move. 7 levels: find 1 of 6 up to 6 of 12.
Click the numbers 1, 2, 3… in order before time runs out. 8 levels: 9 numbers up to 49.
Watch squares light up in order, then repeat it. Level 1: 3 × 3, 10 steps. Level 2: 4 × 4, 12 steps (unlocks after Level 1). A mistake restarts the level.
