How to redeem codes

To redeem codes in Building Simulator, open the Codes menu from the main in-game UI - look for a codes button in the interface. Type or paste your code into the text box and confirm to redeem. Codes are case-sensitive and single-use per account.

Building Simulator codes historically rewarded Cash, Hammer Tool upgrades, Blueprint Boost packs that temporarily multiplied construction earnings, and Helper upgrade bundles. One notable code type enabled offline building - a passive construction mechanic that continued while the player was not in-game, a significant quality-of-life reward for an idle-style game.

The game has not been actively updated since November 2023 and currently has no confirmed active codes. All five historically known codes have expired. Code announcements were made through the Just For Fun Roblox group wall; if new codes appear, they would come through the same channel. New codes are unlikely given the game's inactive development status.
