The TDS5YEARS! code celebrated the game's fifth anniversary, and 1POINT7MIL marked a 1.7 million milestone. Seasonal codes such as HAPPYHALLOWEEN and beachglad2022 tied into specific event windows. These patterns are useful because they tell you when to watch for the next round of codes.
How to Redeem Codes in Tower Defense Simulator
Redeeming codes in TDS takes less than a minute. Follow these steps to claim your rewards:
- Open Roblox and launch Tower Defense Simulator from the game page or search using Place ID
3260590327. - Once you’re in the game lobby, look for the ABX icon at the top right of your screen and click it.
- A code redemption window will appear with a text box for your code.
- Type or paste your code into the text box exactly as shown — special characters like
!and?are part of the code. Match the capitalisation too; no official source confirms whether entry is case-strict, so it is not worth risking. - Click the Redeem button to submit your code.
- If the code is valid, your reward will be credited to your account instantly. Check your inventory or loadout to confirm the reward appeared.
If a code doesn't work, first check whether you own the tower the skin belongs to — that is the most common cause. Then double-check the spelling, capitalisation and any special characters. If it still fails, the code has most likely expired.
What Do Tower Defense Simulator Codes Give You?
TDS codes have rewarded a wide range of items over the years. Knowing what each reward type does helps you understand why certain codes are more valuable than others.
Skin Crates and Premium Skin Crates are the most common code reward. Opening a crate gives you a random cosmetic skin for one of your towers. Premium Skin Crates contain rarer skins with more detailed visual effects. While skins don't affect tower stats or damage output, they let you customize your loadout and stand out in multiplayer lobbies. Rare skins from limited-time crates can become collector's items.
Holiday Crates contain exclusive seasonal items that are only available during specific events. The Christmas Crate from the CHRISTMAS2025 code, for example, included winter-themed tower skins and decorative items. Once the event window closes, these items become unobtainable through normal means, which makes holiday codes especially worth grabbing.
A correction worth making here: TDS codes have never granted an exclusive tower. The MERRY2024 code gave the Cookie Scout, which is a sticker — the only sticker in the game obtainable from a code — not a playable unit. Towers that arrived through codes in the past, like Hunter and Paintballer, were later moved into the in-game store. So codes give you cosmetics and crates, not a strategic roster advantage.
Coins and Resources speed up your progression by giving you currency to spend on tower upgrades and unlocks. While these rewards may seem smaller than a full crate, they reduce the grind and help you reach your next unlock faster. Every free coin is one less you need to earn through gameplay.
How to Get Extra Starting Cash in TDS
Beyond codes, there's a permanent perk that many TDS players don't know about. Joining the Paradoxum Games group on Roblox gives you an additional $100 starting cash at the beginning of every match. This bonus applies automatically as long as you remain a group member.
That extra $100 makes a real difference in the opening waves. It lets you place an additional tower at the start or upgrade your first tower one level sooner than normal. Over hundreds of matches, the advantage compounds significantly. Joining the group is free, takes about ten seconds, and there's no reason not to grab this permanent buff.
Where Do New Tower Defense Simulator Codes Come From?
Paradoxum Games distributes TDS codes through several official channels. Knowing where to look helps you catch codes before they expire.
Twitter / X: The @paradoxum_games account is the primary source for new codes. Most codes are announced here alongside patch notes or event trailers. Developer BelowNatural also shares codes through his personal account. Turning on notifications for these accounts is the fastest way to hear about new drops.
Discord: The official TDS Discord server posts codes in announcement channels. Community members share them quickly after release, and the server is also where you'll find the most detailed information about upcoming updates, balance changes, and event schedules.
Holiday events: Christmas, Halloween, summer, and game anniversary events are the most consistent sources of new codes. The developers have a strong track record of releasing at least one code with each seasonal event. Codes like CHRISTMAS2025, HAPPYHALLOWEEN, and beachglad2022 all followed this pattern.
Milestone celebrations: When TDS hits major favorites or visit milestones, the developers reward the community with a special code. The 1POINT7MIL code celebrated a 1.7 million milestone, and similar milestone codes have appeared throughout the game's history — 2MILLION, still live today, thanks players for 2 million likes. With 4,943,249,815 visits as of August 27, 2026 and 2,061,610 likes, the next milestone code could arrive at any time.
We monitor all of these sources and update this page as soon as a new code is verified. Bookmarking this page saves you the hassle of checking multiple platforms yourself.
Tips for Getting the Most Out of Tower Defense Simulator
Whether you're just starting out or you've been playing TDS for years, these strategies will help you progress faster and clear harder content.
Play cooperatively whenever possible. TDS is built around multiplayer, and having teammates who cover different roles makes clearing harder maps much easier. Coordinate tower placements so you're not doubling up on the same type. A balanced team with damage dealers, support towers, and area-of-effect specialists handles enemy waves far more efficiently than a team running identical setups.
Upgrade strategically, not broadly. Fully upgrading a few key towers almost always outperforms spreading your coins across many half-upgraded ones. A single maxed-out tower delivers more raw damage and wave control than three towers sitting at level 2. Focus your spending on the towers that match the enemy types in the current wave rotation.
Learn the maps and enemy spawn patterns. Each TDS map has specific chokepoints and long paths where towers are most effective. Placing your towers at these positions multiplies their value because enemies spend more time within range. Knowing which enemy types appear in which waves lets you prepare counters before the threat arrives instead of reacting after the fact.
Save skin crates for events. If you're patient, holding onto crates until a seasonal event is active can sometimes yield limited-edition skins. This isn't guaranteed for every event, but it's worth checking event details before opening everything at once.

Frequently Asked Questions
In the TDS lobby, click the ABX icon at the top right of your screen, type or paste your code into the box and press Redeem. One thing that catches people out: both current codes are skin codes, and a skin code will not redeem unless you already own the tower it belongs to.
The most common reason is one this page used to omit entirely: the tower gate. Both current codes are skin codes, and a skin code will not redeem unless you already own the tower it applies to — Shotgunner for 1MILCOMMUNITY, Pursuit for 2MILLION. Beyond that, codes fail if they have expired or you have already used them on that account. Enter codes exactly as written, punctuation included — many TDS codes contain characters like ! and ?. We should note that no official source actually states whether entry is case-strict, so matching the capitalisation is a precaution rather than a documented rule.
New TDS codes are released on an irregular schedule, often tied to holiday events, game anniversaries, player count milestones, and major content updates. Paradoxum Games doesn't follow a fixed timeline, but you can generally expect a few codes per year around significant events. We update this page as soon as any new code is confirmed.
No. Each code can only be redeemed once per account. Attempting to use a code you've already claimed will result in an error message. You can't redeem the same code on the same account twice, but you can use the same code on different Roblox accounts.
Yes. Most TDS codes have a limited window of availability. The developers can deactivate codes at any time without advance notice. Event-specific codes like CHRISTMAS2025 typically expire when the associated event ends, while milestone codes may last slightly longer. The safest approach is to redeem every code the moment you find it.
Join the Paradoxum Games group on Roblox. As a member, you receive a permanent bonus of $100 starting cash at the beginning of every match. This perk is free and applies automatically as long as you stay in the group.
TDS codes have historically given out skin crates, premium skin crates, holiday crates, tower skins, in-game coins and experience boosts. One correction to a claim that circulates widely: the Cookie Scout from MERRY2024 was a sticker, not a tower. No TDS code has granted a permanently exclusive playable tower.
