About 60 seconds. Not medical advice. Stop if you feel dizzy, nauseous or strained.
Some squares light up for a moment. Then tap the same squares, in any order. Each level adds a square and the grid grows. Three wrong taps in one level cost a life; you have 3 lives.
This tests visual short-term memory: holding a picture in mind for a few seconds. 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.
