In a flash
See the numbers, then find them in order after they are hidden.
Try this taskChimpanzee Challenge
Numbers vanish. Does your memory hold?
Remember positions, then uncover the sequence.
What you will do
The chimpanzee challenge combines number order with spatial memory. Seeing a sequence is only the beginning: after the tiles are covered, you must select their positions in ascending order.
The tasks cover the tiles after a short exposure, after your first touch, or present a sequence with gaps. Missing numbers do not create extra tiles. The goal is to follow the numbers that were actually shown, from lowest to highest.

No 1? Remember an incomplete number sequence.
Try this taskHow the animal challenge works
Three tests with five rounds each. You have one life: every round must be correct. Tests become harder automatically, from Light through Medium to Demanding. Before each test, take your time with the rules and example. Choose relaxed or sport tempo; the clock starts when you start the task.
What to watch for
- Group nearby numbers into a route across the board instead of remembering each tile separately.
- In a gapped sequence, continue with the next number that appeared; do not search for an absent one.
Before you play
Where should I start?
Open one task and read its goal and example before starting. Training lets you choose the task profile and tempo.
How many rounds are there?
Each task has five rounds. Training allows one wrong round; one-life challenges require all five to be correct.

The idea behind the games
These are original game tasks, partly inspired by animal cognition research. The research notes link to the original papers and explain how our game ideas relate to them. Read the research notes.
