We checked for new codes!

Tower Defense Simulator, as the name suggests, is all about defending your tower and building the largest, most powerful army possible. In order to do this, and do it successfully, I needed a fair amount of Coins and Gems—so how did I get them quickly and without spending hours grinding? Not everyone has time to grind through waves of enemies for hours on end, so there had to be a way around this. The answer? With these Tower Defense Simulator codes!

Luckily, Pro Game Guides has you covered with the most up-to-date and OP TDS codes that you can use to unlock tons of Gems, Coins, and even some code-exclusive tower skins completely free! If you find a code in the Active Codes section that appears to be expired, please let us know so we can remove it as soon as possible. Also, keep in mind that you must enter each code exactly as it is written, otherwise the experience will not accept it!
