How to play: The robot is packing for a picnic on the moon. Every item it brings follows a secret rule.

Each round, the robot announces an item. Pick an item from the grid that you think follows the same rule. For example, if the rule is "things that are round," the robot might bring a globe — and you could bring a basketball.

Get 3 correct in a row to win. After your first pick, you can also press "I know the rule!" to identify all matching items from a set of 8.
