How to Play
- Read the rule
The banner says whether colour, shape or number counts.
- Send the card
Two bins, one tap. The bins swap sides at random.
- Catch the switch
The rule changes mid-run. Habit is the enemy.
Rule Switch
Sort each card by the rule on the banner. The rule changes when you least expect it, and the hard part is noticing.
Ready to test your mental flexibility?
One card at a time, two bins, and a rule that quietly changes underneath you. Sixty seconds.
Read the banner before every card. It will not warn you when it changes.
What It Challenges
- Cognitive flexibility
Drop a rule the moment it stops applying.
- Inhibition
Override the answer your hands already learned.
- Processing speed
Do all of that without slowing down.
