Squares light up, then vanish. Tap the ones that lit up — in any order. One more square every level.
Half of players reach level 8
A pattern of squares lights up on the grid for about a second, then disappears. Tap the squares that were lit — the order does not matter. Clear the level and the next one adds another square, with the grid itself growing every few levels.
You get three lives, and a failed level can be retried. Half of the people who play it here reach level 8. The reliable trick is to stop counting squares and start seeing the shape they make: one outline is a single thing to remember, where six positions are six.

Level 9 or more. The middle score here is level 8, on a computer or a phone; level 10 puts you in the top 10% on a computer.

Order. The chimp test makes you tap numbers in sequence, so it tests memory for order as well as position. Here only the positions matter, which is a surprisingly different skill.
Look at the shape the squares make rather than the individual squares. Most people who do well describe remembering a single outline rather than a list of positions.
