How to redeem codes

To use codes in Build Your Gym, look for the codes button or input field in the gym management UI. Enter your code and confirm to claim your reward. Entering codes exactly as written is the safest approach, as case sensitivity has not been confirmed.

Codes reward Magma Boxes, which are higher-tier mystery boxes with better equipment odds than standard boxes. Getting Magma Boxes from codes gives you a head start on collecting quality machines and boosts your passive income before you would normally unlock that tier through normal play. A single code like hello100, which gives 50 Magma Boxes, can significantly advance your gym's earning potential in the early game.

New codes are released by the Your Gym Game developer group at update milestones. With the game in active development since December 2025 and regular updates through 2026, new codes tend to arrive with major content additions. Check the developer group page and game description for the latest announcements.
