Get free gems, coins, and skins with these Tower Defense Simulator codes. (Updated: August 2025)
Tower Defense Simulator is one of the most popular games on the Roblox platform. The game very much does what it says on the tin, a tower defense game with plenty of game modes and levels to grind.
You need to train up troops and level up your towers before fighting off waves and waves of zombies. There are also plenty of cosmetics to acquire to custom your towers and troops to your heart's content.
To do that, you must get your hands on coins and gems. Coins can be used to purchase towers, emotes, and skins. These are rewarded after completing a match or by purchasing them using Robux.
Gems are rewarded after completing Hardcore mode matches and can be used to purchase towers.
Thankfully, there is a way of acquiring these two in-game currencies without having to play any matches, and that is by using Tower Defense Simulator codes.
These codes can be used to redeem in-game items, including coins and gems, making the grind up the levels a little bit easier.
