How to redeem Tower Defense Simulator codes

Step 3: Submit the code. When redemption works, the reward is added to your account immediately.

How code rewards work in Tower Defense Simulator

Manual codes are created directly by the developers. These rewards can include Coins, Gems, EXP, towers, emotes, crates, and skins, though most manual codes are only redeemable for a limited time.

Some codes are also stock-limited rather than time-limited. Once those redemptions run out, the code stops working even if it was active for other players earlier.

Skin codes have one extra requirement. You must already own the matching tower before the skin can be redeemed.

Merchandise code rewards

Merchandise codes are separate from standard manual codes. These were unique single-use codes tied to specific products, and code generation for those items is unavailable.

Items tied to merchandise codes include rewards such as Plushie skins, boss-themed nametags and charms, and a small number of crate bundles. If a qualifying product was refunded, the associated reward could be revoked, and an unredeemed code tied to a refunded item could be voided.

Tower Defense Simulator also carries a warning around fraudulent or illegally obtained codes. Using or sharing those codes can lead to a ban from playing the game.
