Hamster Simulator

Hamster Simulator is an animal roleplay sandbox game on Roblox developed by Hamster Multiverse, created in June 2018. With 61.1M+ visits accumulated over nearly eight years of continuous operation - including an update in April 2026 - it remains one of the longest-running animal simulation games on the platform. A sequel, Hamster Simulator 2, is also available from the same developer.

Players become a hamster and explore a large open world outside their cage, collecting Coins, completing quests, and discovering 12 hidden secret locations tied to badge achievements. The game's standout feature is its variety of playable species and movement options:

• 🗺️ Explore a large open world as a hamster, discovering 12 hidden secrets and easter eggs
• 🎭 Play as a Cat (gamepass) with claws, faster speed, bigger size, and the ability to harm other players
• 🚗 Roll in a Hamster Ball in multiple color variants, or fly via the Hamster Plane gamepass
• 💎 Unlock the Rainbow Hamster species for free as a Premium Roblox member
• 💼 Customize with hats, particles, and the Hamster Roped grappling hook for fast traversal

The Cat gamepass is the most distinct option - cats are faster, jump higher, are larger than hamsters, and have claws that can harm other players and cats. This creates a natural predator-prey dynamic on shared servers. The White Mouse is a subtler alternative at 70 Robux, slightly faster than the standard hamster. Baby Hamster Pets (three companion options) add a collectible layer for completionists.

Premium Roblox members receive the Rainbow Hamster and Wizard Hat for free - a meaningful perk that adds cosmetic variety without any Robux spend.
