Run Star Simulator

Run Star Simulator is an athletic running-themed incremental simulator on Roblox developed by verified group BestBunny, where players train Speed and Strength stats, compete in sprint races to earn Wins, and collect Pets for passive multipliers. Launched in April 2023, it has accumulated over 123 million visits with a 97.8% approval rating across more than 412K votes - one of the highest approval rates of any simulator on the platform. The current version carries the subtitle "Tung World," reflecting a major content expansion added in recent updates.

The core loop involves sprinting to train Speed and Strength, completing races to earn Wins, and spending Wins on upgrades that increase running speed and Wins income per race. Pets form a parallel collection track - companions that passively boost Speed, Wins income, or luck when rolling for rarer pets. Each progression track feeds the next, making the sprint-earn-upgrade cycle feel consistently rewarded:

• 🏆 Wins - primary currency earned from completing races; funds all upgrades and progression
• 💪 Speed and Strength - core stats trained through the active running and racing mechanic
• 💎 Pets - passive companions providing Speed multipliers, Wins bonuses, or pet roll luck
• 🗺️ Tung World - the current major content expansion adding a new progression area to the base game
• ⏳ Session 2 - prestige-style layer extending the progression path for players past the base content cap

BestBunny uses the BestBunny Roblox group as the primary code distribution channel - the game description explicitly says "Join The Group For Codes & Report Bugs!" Servers hold 20 players.

Run Star Simulator is one of the most successful athletic simulators on Roblox by approval rating and visit count. Players who enjoy this format will also find Run To Win Simulator and Running Incremental worth exploring, though neither matches BestBunny's 123M visit scale.
