Looking for working Ultimate Tower Defense codes? You are in the right place. Below you will find every confirmed active code for Ultimate Tower Defense on Roblox, along with a complete list of expired codes and a step-by-step redemption guide. We check for new codes regularly and update this page as soon as fresh rewards drop.
Ultimate Tower Defense (UTD) is one of the most popular anime-inspired tower defense games on Roblox, where players collect and deploy powerful units based on iconic anime and manga characters to fend off waves of increasingly difficult enemies. The game blends strategic tower placement with gacha-style unit summoning, trait and perk systems, and a deep progression loop that keeps players coming back for hundreds of hours.
The developers regularly release promotional codes that reward players with free Rubies, Perk Rerolls, Trait Rerolls, Battlepass EXP, event currencies, and other valuable items. These codes typically coincide with game updates, seasonal events, community milestones, and special celebrations. Since codes can expire without warning, redeeming them as soon as you find them is always the smart move.
With the recent launch of Update 50 featuring DBZ PT. 1 content and the ongoing Egg Hunt event, there has never been a better time to jump into Ultimate Tower Defense. The codes listed below will give you a head start on rerolling your units for the best perks and traits, stocking up on Rubies for summoning, and progressing through the current Battlepass season.

How to Redeem Codes in Ultimate Tower Defense
Redeeming codes in Ultimate Tower Defense takes less than a minute. The code redemption system is accessible from the game lobby before you start a match. Follow these steps to claim your free rewards:
- Open Roblox and launch Ultimate Tower Defense from the game page.
- Once you are in the game lobby, look for the blue Twitter bird icon on the left side of the screen and click on it.
- A code redemption window will open with a text input field where you can enter your code.
- Paste your code into the input field exactly as shown — codes are case-sensitive, and many include special characters like exclamation marks (!) and question marks (?) that must be included.
- Press the Redeem button to submit your code.
- If the code is valid, your rewards will be added to your account instantly. You will see a confirmation message on screen showing what you received.
If a code does not work, double-check the spelling, capitalization, and special characters first. If it still fails, the code has likely expired. Come back to this page to see the latest working codes as they are released. Make sure you are entering the code from the lobby and not during an active match, as the Twitter icon is only accessible from the main menu.
All Expired Ultimate Tower Defense Codes
The following codes have been deactivated and can no longer be redeemed. We keep them listed here for reference so you do not waste time trying codes that no longer work.
| Code | Status |
|---|---|
| HalloweenSoon! | Expired |
| SaveYourPumpkins! | Expired |
| KeepUpTheGrind! | Expired |
| QoL&Bugfixes! | Expired |
Looking at the expired list, you can spot common patterns in how the developers release codes. Seasonal event codes like HalloweenSoon! and SaveYourPumpkins! are tied to limited-time holiday events and expire once the event ends. Update codes like QoL&Bugfixes! arrive alongside specific patches and quality-of-life improvements. Motivational codes like KeepUpTheGrind! tend to be short-lived community rewards. These time-sensitive codes typically expire within a few days to a couple of weeks, which is why claiming active codes as soon as you find them is always the best strategy.
What Do Ultimate Tower Defense Codes Give You?
Ultimate Tower Defense codes reward players with a wide range of in-game currencies and items. Understanding what each reward does helps you make the most of your free loot.
Rubies and Gems
Rubies and Gems are the primary currencies in Ultimate Tower Defense used for summoning new units and purchasing items from the in-game shop. Free Rubies from codes like 1AprilKikkerInJeBil! (420 Rubies) and Easter! (1,000 Rubies) give you extra summoning attempts without grinding or spending Robux. Even smaller amounts add up quickly when you redeem every available code, and a lucky summon from free currency can completely transform your lineup.
Perk Rerolls and Trait Rerolls
Perks and Traits are bonus attributes assigned to your units that can significantly impact their performance in battle. Perk Rerolls and Trait Rerolls let you re-randomize these attributes until you land the ideal combination for each unit. Getting the right perks and traits on your strongest characters is one of the most important optimization steps in the game, and rerolls are normally expensive to acquire. Codes like CanYouMakeACode? (150 Perk Rerolls) and BattlepassSeason8! (80 Trait Rerolls) save you a significant amount of grinding.
Event Currencies and Special Items
Some codes reward event-specific currencies like Pumpkins, Shark Heads, Chainsaw Heads, and Lost Chests. The ThankYouFor3K! code gives 15,000 Pumpkins, 60 Shark Heads, and 20 Chainsaw Heads, which can be used in their respective event shops to purchase exclusive units and items. Lost Chests from the BattlepassSeason8! code contain randomized loot that can include rare units and upgrade materials. These event currencies are often harder to farm than standard currencies, making code rewards especially valuable during active events.
Battlepass EXP
The BattlepassSeason5 code rewards 5,000 Battlepass EXP, which helps you progress through the Battlepass tier system faster. Each tier unlocks exclusive rewards that are only available during that Battlepass season, so extra EXP from codes helps you reach the higher tiers and claim the best rewards before the season ends.
Where Do New Ultimate Tower Defense Codes Come From?
The Ultimate Tower Defense development team releases codes through several channels. Knowing where to look gives you the best chance of catching codes before they expire:
Developer Discord server: The official Ultimate Tower Defense Discord server is the primary source for new codes. The developers post codes in dedicated announcement channels, and community members often share them within minutes of release. Joining the Discord is the single best way to get codes the moment they go live.
X/Twitter: The official UTD Twitter account posts codes alongside game update announcements and event teasers. Following this account with notifications turned on ensures you see new codes as soon as they are tweeted.
Game updates: Codes like UltimateApril2026Delay and GameSpeedWoah! are released alongside significant game patches. Every major content update, balance change, or new feature typically comes with at least one new code. The current Update 50 featuring DBZ PT. 1 content and the Egg Hunt event brought several new codes with it.
Seasonal events: Holiday and seasonal codes like Easter2026, Easter!, NearlyNewYear2026!, and Summer2025! are tied to calendar events. These tend to be some of the most generous codes in terms of reward value, so keeping an eye out during holidays and seasonal transitions is always worthwhile.
Battlepass launches: Each new Battlepass season brings dedicated codes like BattlepassSeason8! and BattlepassSeason5. These codes typically include Battlepass EXP to kickstart your progression, along with Perk and Trait Rerolls, and sometimes exclusive chest rewards.
Community milestones: When Ultimate Tower Defense hits player count milestones, like 3,000 concurrent players (ThankYouFor3K!), the developers celebrate with special codes. As the game continues to grow, more milestone codes will follow.
We monitor all of these sources and update this page as soon as new codes are confirmed, so bookmarking this page is the easiest way to stay on top of every code drop.
Tips for Getting the Most Out of Ultimate Tower Defense
Beyond redeeming codes, there are several strategies that can help you progress faster and build a stronger team in Ultimate Tower Defense. For a complete breakdown of strategies and ways to earn free Robux for gamepasses, check out our Ultimate Tower Defense free Robux guide.
Use Perk and Trait Rerolls strategically. Do not waste your rerolls on every unit in your collection. Focus your Perk Rerolls and Trait Rerolls on your strongest and most frequently used units first. Getting the right perk and trait combination on a top-tier unit makes a much bigger difference than having mediocre rolls across your entire roster. Since codes give you a healthy supply of rerolls, save them for the units that matter most.
Take advantage of event currencies immediately. Event currencies like Pumpkins, Shark Heads, and Chainsaw Heads are only useful during their respective events. When you redeem codes that give event currencies, spend them in the event shop before the event ends. Event-exclusive units and items cannot be obtained once the event is over, making these rewards especially time-sensitive.
Progress through the Battlepass early. The Battlepass rewards get better at higher tiers, but you need to complete the entire pass before the season ends to claim everything. Codes that give Battlepass EXP give you a head start, and combining that with daily and weekly challenges accelerates your progression. Do not wait until the final week of the season to start grinding.
Save Rubies for rate-up banners. While it is tempting to summon the moment you have enough Rubies, waiting for rate-up or limited-time banners dramatically increases your chances of pulling specific high-tier units. Codes that give free Rubies make this easier since you can build a stockpile without feeling like you are falling behind on progression.
Redeem every code immediately. Even codes that seem to give small amounts of rewards add up over time. With thirteen active codes on this page, you can collect a massive haul of Rubies, rerolls, event currencies, and Battlepass EXP in just a few minutes. Players who stay on top of every code have a significant resource advantage over those who skip them.

About Ultimate Tower Defense
Ultimate Tower Defense is a tower defense experience on Roblox that draws heavy inspiration from a wide range of anime and manga series. Players summon and deploy units inspired by franchises like Dragon Ball Z, Naruto, One Piece, Jujutsu Kaisen, Demon Slayer, and many more, then strategically place them on the battlefield to defend against waves of enemies that grow more powerful with each round.
The gameplay revolves around team building, unit optimization, and strategic placement. Each unit has unique abilities, stats, perks, and traits that determine their effectiveness in battle. The perk and trait system adds a deep layer of customization, where players use rerolls to find the ideal attribute combinations that maximize each unit's damage output and utility. Units can also be upgraded and evolved into stronger forms that unlock new abilities and significantly boost their combat performance.
Ultimate Tower Defense features multiple game modes including story mode, endless mode, challenge stages, and seasonal events like the current Egg Hunt. The Battlepass system adds a layered progression track with exclusive rewards for each season. The game receives regular updates that introduce new characters, maps, events, balance adjustments, and quality-of-life improvements. Update 50, the latest major patch, brought Dragon Ball Z PT. 1 content alongside the Egg Hunt event, giving both new and returning players plenty of fresh content to explore.
Whether you are a new player building your first team or a veteran min-maxing your perk and trait rolls, staying on top of active codes gives you a real edge. Free Rubies mean more summoning attempts, free rerolls mean better optimized units, and free event currencies mean exclusive rewards you cannot get anywhere else. Combined with the strategies in our Ultimate Tower Defense free Robux guide, you have everything you need to build a top-tier team without spending a dime.
