How to redeem codes in Tower Defense Simulator
Codes are redeemed from the lobby while you are not in a match. The game accepts codes only through the dedicated Codes interface, and most codes can be used once per account.
Step 1: Launch the Tower Defense Simulator experience on Roblox and wait until you are fully loaded into the lobby.
Step 2: In the lobby, locate the Codes button or the Twitter-style icon (labeled for codes) on your screen and select it to open the code entry window.
Step 3: Click into the text field, then carefully type or paste an active code exactly as shown, matching all capital letters, numbers, and symbols.
Step 4: Press the Redeem button. If the code is valid and still active, a confirmation message appears and the crate, skin, or other reward is added to your account inventory.
Skin codes only work if you already own the required tower. For example, commander or cowboy skins cannot be claimed if those towers are locked on your profile.
How to confirm that a Tower Defense Simulator code worked
A successful redemption is always accompanied by an on-screen confirmation message stating that the reward has been granted. You can then verify the reward in the relevant menu.
- Crates appear in your crate inventory and can be opened from the cosmetics section.
- Skins appear in the tower customization menu for the matching tower.
- Coins, Gems, or XP are added directly to your balances and level progress.
If no message appears, or you see an error stating that the code is invalid or expired, that code can no longer be used on your account.
Why Tower Defense Simulator codes may not work
When a Tower Defense Simulator code fails, it is usually for one of the following reasons.
- Code expired: Most manual codes are time-limited or tied to specific events and stop working after the event ends.
- Spelling or formatting error: Codes are case-sensitive, and missing characters such as
!or?will cause redemption to fail. - Tower requirement not met: Some skin codes require that you already own the relevant tower; without it, the code cannot be redeemed.
- Account already used the code: Each account can only redeem a given code once. If you claimed it previously, it cannot be used again.
Other ways to get rewards in Tower Defense Simulator
Codes are only one of several ways to build up cosmetics and resources in Tower Defense Simulator.
- Daily login rewards: Claim the daily reward from the upper part of the lobby interface each day you log in.
- Tutorial completion: Finishing the tutorial for the first time grants starting cash to accelerate early progression.
- Quests and badges: Completing quests grants XP and other rewards, and some badges have claimable rewards through the rewards menu.
- Roblox group bonus: Joining the official Paradoxum Games Roblox group grants an extra $100 starting cash bonus on new accounts.
Where new Tower Defense Simulator codes usually appear
New codes for Tower Defense Simulator typically arrive around holidays, major events, or player milestones. They are distributed through official game channels and may be limited by time or by number of redemptions.
- The official Tower Defense Simulator Discord server is used for announcements and new code reveals.
- The developer’s X (Twitter) accounts are also used to share codes during events and celebrations.
Checking these channels regularly and redeeming codes promptly is the most reliable way to claim future crates and cosmetics.
