Raise a Peter

Raise a Peter is an incremental simulator by Petir Greffins where players raise and care for Peter, a character likely inspired by Family Guy's Peter Griffin given the developer group name. Launched in May 2022 during the peak of the raise-a-floppa wave, it has grown to over 82 million visits and 255K favorites with an 81.1% approval rating - solid retention for a game that has been actively updated through February 2026.

The core mechanic is high-stakes by design: if Peter starves, your save is deleted. That single rule transforms the routine act of keeping a character fed into a constant background priority - you cannot neglect him for too long without consequence. The loop builds from that tension, asking players to interact with and grow Peter through repeated care actions while managing the hunger timer:

• 🎭 Keep Peter fed and happy to maintain your progress and save file
• 💰 Build incremental stat and level gains through consistent daily interaction
• 🗺️ Share servers with up to 100 players - the largest server cap in the raise-a genre
• ⏳ Active updates added through February 2026 keep content growing
• 🎭 Level and stat progression tied to how well and how long you maintain Peter

What distinguishes Raise a Peter from most games in the genre is the 100-player server limit. The vast majority of raise-a games use single-player servers, making this a social and multiplayer-first design. Competitive raising and cooperative events become possible at that scale in ways they are not in one-player servers.

If you enjoy the raise-a format, the original raise a floppa and raise a floppa 2 are the genre's benchmarks, both built around deeply personal single-player experiences with their own distinct mechanics.
