✅ Last Verified: June 2026 | 18 active codes | 0 expired logged
Strongman Simulator’s 18 active codes are heavy on timed boosts rather than flat currency, meaning stacking them back-to-back opens a long multiplier window for a full rebirth sprint. 400M runs a 2x Energy boost for 15 minutes (the longest single timer on the list), strongman and Chad each drop a free Duck-type pet, and the Shazam! trio of codes came bundled with the Shazam movie crossover event.

🎮 About Strongman Simulator
Strongman Simulator by The Gang Stockholm is a lift-to-win sim where every rep you finish adds Strength and Energy, Energy determines how many reps you can push, and Strength caps determine which weight plates you can load. The goal is to chain rebirths, unlock harder lifts, and farm for cosmetic pets that buff stats.
The active code list is almost entirely timed 2x Energy and 2x Workout Speed boosts rather than flat currency drops, so stacking multiple timed codes at once gives a long multiplier window for a rebirth sprint. The Chad and strongman codes are the odd ones, each unlocks a free Duck-type pet instead of a boost, and the Shazam! trio (Shazam!, TruePowerOf, LearnThe, Shazam!FuryOfTheGods) shipped with the Shazam movie crossover event.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
