Tower Defense Simulator tasks players with holding a base against waves of enemies using towers ranging from basic gunners to specialized support units. Codes from developer Paradoxum Games hand out crates, skins, coins, and experience that speed up progress toward unlocking stronger loadouts.

What codes actually reward
Most codes hand out skin crates, cosmetic tower skins, coins, or small experience boosts rather than gameplay-changing units. That lines up with how progression works in the base game, where stronger towers are earned through cash spent during matches rather than through code redemption alone.
Codes work alongside a handful of other free reward sources built into the game. The table below breaks down what each method offers.
| Reward method | What you get | Frequency |
|---|---|---|
| Codes | Crates, skins, coins, XP | Whenever new codes release |
| Daily login | Cash and bonuses | Once per day |
| Quests and missions | XP, cash, and items | Repeatable |
| Badges and achievements | Milestone rewards | One time per badge |
| Roblox group membership | $100 starting cash | One time |
Where new codes get announced
Paradoxum Games typically shares new codes to mark community milestones, holidays, or major updates rather than on a fixed schedule. The official Tower Defense Simulator Discord server is usually the fastest place to catch an announcement, and the developer also posts through the @paradoxum_games and @BelowNatural accounts on X.
Since codes can be pulled without warning, it’s worth redeeming a working code as soon as you see it rather than saving it for later.
