Zogen

In Zogen, the player researchers want to rid themselves of their microorganism cards as quickly as they can, but they can do so only by observing the current lab environment and watching the one thing that changes, then recording it by playing their card. In more detail, each player starts with a hand of sixteen cards, with each card showing 0-4 types of microorganisms, which are named Maru, Tsuki, Yama, and Siri. The start player for the round places one of their cards face up on the table, then everyone plays at once, trying to lay down a card that differs from the initial card by exactly one microorganism, whether one more or one less.
