Updated August 8, 2024: We've checked for new codes!

Tower Defense Simulator is an extremely popular game on Roblox. It is a game concept that has been around for over a decade, but users keep coming back to it because of the game’s extremely addictive gameplay. The game, as the title suggests, revolves around protecting your tower from hordes of enemies. These enemies become increasingly stronger over time, meaning that players will have to upgrade their tower’s defenses more and more.

To do this, players will need access to as many coins and gems as possible. While these currencies can be obtained through gameplay, players can also add them to their inventory via promo codes. These codes change every month, meaning players will need to stay up to date if they want access to every possible code.

Below you can see all the active codes that currently work in Tower Defense Simulator, as well as the codes that have expired.
