Rat On The Run is a free-to-play game developed by Donut Games for Android devices. The game is set in a house with blocks of cheese scattered throughout. The player helps Ratty, the hungry rodent, fill up his growling stomach by grabbing the cheese blocks. The more cheese Ratty eats, the more points the player scores. However, there are baddies like slimy blobs and spiders that will try to stop Ratty from eating. The game features three modes: "Challenges" with 60 levels, "Arcade Mode" with 8 floors, and "Rat On A Scooter" mini-game that was later launched as a separate app with additional features. The game has simple, responsive controls and lots of achievements to unlock. Rat On The Run is free from ads and can be played without any cost, but a premium upgrade is available as an optional one-time in-app purchase.
