How to Redeem Codes in Tower Defense Simulator

Open Tower Defense Simulator on Roblox and let the game finish loading before attempting to redeem anything.

Locate the Codes icon in the upper-right corner of the screen and click it to bring up the redemption window.

Type or paste a working code into the text field. Every character must match exactly, including question marks, exclamation points, and any mixed-case letters.

Press Redeem. A confirmation message appears when the reward is successfully added to your account. If the code is expired or does not match, you will either see an error notification or receive no response.

How to Find More Tower Defense Simulator Codes

The developer posts new codes through the official @paradoxum_games account on X and the Tower Defense Simulator Discord server. Both channels tend to receive announcements as soon as a code goes live, often ahead of other platforms.

New players can also claim a free +$100 starting cash bonus by joining the Paradoxum Games Roblox group. It’s a small but useful head start for placing your first towers before the early waves arrive.

Other Ways to Earn Rewards in Tower Defense Simulator

Codes aren’t the only path to free items. Daily Rewards refresh each session and appear at the top-right corner of the screen — worth grabbing every time you log in. Coins, the primary currency used for most purchases, come from completing Normal, Molten, and Fallen modes. Gems are rarer since they drop exclusively in Hardcore mode, though their purpose is narrow: purchasing the late-game Accelerator and Engineer towers.

Earning XP through regular play levels you up and unlocks additional troops, all visible in the Rewards menu. A broader roster opens up more strategic options when heading into different maps and difficulty settings.
