This one is called Rise of the Half Moon, and it’s one of those interactive card games. The premise is simple: you play against an artificial opponent and get cards to play with different phases of the moon. You get points if you match cards next to each other, or if you cards “create” a full moon. You also get points for creating a lunar cycle.

Google’s famous doodles — the illustrations that show up in place of the Google logo nearly every day — have been known to take the form of surprisingly great games on occasion.

Google has released its 2024 Halloween Google Doodle game, featuring the return of a cute magical black cat who fights ghosts.
