Tower Defense Simulator codes are rare, and right now they only give tower skins: a Mercenary skin for Pursuit and a Community skin for Shotgunner. There are no live codes for coins, gems or crates. This page lists every working code we could verify, the date we checked it, and the catch most code lists skip: you have to own the tower before its skin code will redeem.
Quick answer (checked October 26, 2026): 2 codes are active: 2MILLION (Mercenary Pursuit skin) and 1MILCOMMUNITY (Community Shotgunner skin). To redeem, open the code box in the top-right corner of the lobby (the "ABX" icon), type the code exactly as shown and confirm. You must already own Pursuit or Shotgunner to claim the matching skin.

What are the active Tower Defense Simulator codes?
| Code | Reward | Tower you need | Status (Oct 26, 2026) |
|---|---|---|---|
| 2MILLION | Mercenary skin | Pursuit | ✅ Active |
| 1MILCOMMUNITY | Community skin | Shotgunner | ✅ Active |
How we verified them: 2MILLION comes straight from the developer. The game's own Roblox description reads: "Thank you for 2 MILLION likes! Use code 2MILLION for a free Mercenary Pursuit skin!" 1MILCOMMUNITY isn't in the description, so we required independent sources: it's listed as active on the TDS Wiki codes page, and as working on PCGamesN (September 28, 2026), Eurogamer (October 15) and Pro Game Guides (October). The wiki dates both codes to June 2026. This is source verification: we haven't redeemed them on our own account.
The game is very much alive. Our Roblox Games API pull at 00:06 UTC on October 26, 2026 showed 14,806 players online, 5.04 billion visits, 3.53 million favourites and a 94.1% like ratio (2.09M up, 130k down). The API lists the last update as October 23, 2026, which was version 2.16.0 with the Solar Requiem Night III release and the Hollow Crate.
What do the code rewards actually do?
Both rewards are cosmetic skins. Neither changes damage, range or fire rate. Here's what it takes to use each one, according to the TDS Wiki:
- Mercenary skin (2MILLION): a skin for Pursuit, a high-damage tower that fires rockets and can patrol the map. Pursuit isn't a starter tower. You can buy it for 15,000 coins once you reach level 100, or unlock it early at any level with the 1,500 Robux Pursuit gamepass (wiki, gamepasses). What matters for the code is owning the tower, not your level.
- Community skin (1MILCOMMUNITY): a skin for Shotgunner, a cheap close-range tower that costs 850 coins (wiki). That's within reach for almost any account, so this is the easier code to claim.
Our advice: redeem 1MILCOMMUNITY now if you own Shotgunner (or buy it for 850 coins first). Don't buy Pursuit just for a skin. It's worth getting because it's a strong mid-to-late-game tower, and the Mercenary skin is a bonus on top.
How do you redeem codes in Tower Defense Simulator?
- Launch Tower Defense Simulator on Roblox and stay in the lobby. Codes can't be redeemed during a match.
- Look at the top-right corner of the screen and click the code icon with the letters "ABX".
- Type a code into the box exactly as shown, including capital letters.
- Confirm to claim the reward.
Why is my Tower Defense Simulator code not working?
Most failed codes come down to one of these:
- You don't own the tower. This is the big one. Skin codes only work if you already have the tower the skin belongs to. Buy Shotgunner or Pursuit first, then redeem.
- You already used it. Each code works once per account.
- There's a typo or wrong case. TDS codes have used mixed upper and lower case (like 4BVisits), so type them exactly as written. Copy and paste is safest.
- It's expired or out of stock. Many TDS codes have had a time limit or limited stock. For example, celebration21 had 200,000 redemptions and 1BILLION lasted 24 hours, according to the wiki.
- It's an old code that some sites still list. CHRISTMAS2025 still shows up as working on some code lists. The wiki marks it expired.

How do you get more Tower Defense Simulator codes?
Paradoxum Games often releases codes for milestones and celebrations, and codes aren't guaranteed with each update. Look at the history: 1BILLION and 4BVisits for visit counts, 2MILLION for likes, TDS5YEARS! for the anniversary, and a Christmas code most years. Don't expect one every patch. The next likely moments are Christmas 2026 and the game's next big visit or like milestone. These are the official places to watch:
- The Paradoxum Games group on Roblox: about 6.06 million members. Joining also gives you +$100 starting cash in every match, according to the game's description. That's a separate perk from codes.
- Paradoxum's X account (@paradoxum_games): the source the wiki cites for most past codes.
- The official TDS Discord: the wiki cites code announcements posted there. Use the link on the game's Roblox page, not invites from comment sections.
The Solar Requiem event is running right now, from October 9 to November 19, 2026, across four Nights (wiki). It hasn't come with a code so far, so the event's rewards come from playing it. You level the Solar Requiem Battle Pass with Lunar Shards earned in matches and event maps, or skip levels with Robux (wiki). The event also added the Sun and Moon Crate and the Hollow Crate, which carries Halloween-themed tower skins.
We re-check this page regularly, so bookmark it instead of trusting an old video.
Is Tower Defense Simulator still worth playing in 2026?
Yes. Nearly 15,000 people were playing at 3 AM Moscow time on a Monday, and the game is still getting weekly event content seven years after its June 2019 launch. The description sums up the loop: "Place units to defend against hordes of zombies! Team up with friends and face against even stronger bosses to unlock new units!" You earn coins from matches, buy towers, and climb levels to unlock stronger ones like Pursuit.
