I’ve been grinding Tower Defense Simulator since 2019. Back when John was a code reward and the Frost Event was the hardest thing in the game. These days TDS is a completely different beast with Hardcore mode, exclusive towers, and events that actually require strategy.
Real talk: Tower Defense Simulator codes are rare. The devs at Paradoxum Games don’t hand them out like candy. When a code drops, it’s usually tied to a milestone or holiday event. Miss it and you’re out of luck.
All Working Codes
| Code | Reward |
|---|---|
| CHRISTMAS2025 | 1 Christmas 2025 Skincrate |
That’s it. One active code right now. TDS codes expire fast and have limited stock. The CHRISTMAS2025 code dropped on December 25th, 2025, so grab it while it’s still active.
How to Redeem Codes
- Launch Tower Defense Simulator
- Look for the Twitter icon at the bottom of your screen in the lobby
- Click it to open the code redemption box
- Type or paste your code exactly as shown
- Click Redeem
Codes are case-sensitive. CHRISTMAS2025 works. christmas2025 doesn’t. Copy-paste to avoid typos.

Where to Find New Codes
TDS codes drop rarely. Here’s where to check:
- Paradoxum Games Discord - Codes drop here first, usually with limited stock
- @paradoxum_games on Twitter/X - Official announcements
- @BelowNatural on Twitter/X - Lead developer, sometimes posts codes
- Tower Defense Simulator on Roblox - In-game news feed
Most codes have limited stock. The 4BVisits code had maybe 50,000 uses before it ran out. If you see a new code, redeem it immediately.
What Codes Give You
TDS codes typically reward:
- Skincrates - Contain cosmetic skins for your towers
- Coins - Buy towers and upgrades
- Gems - Premium currency for special items
- Exclusive Skins - Limited-time tower cosmetics
- EXP - Level up faster
Skincrates are the most common reward. They don’t affect gameplay but some skins look incredible. The Golden Minigunner skin from the Golden Minigunner Plush? Chef’s kiss.
Earning Currency Without Codes
Since codes are rare, here’s how to actually progress:
Grind Molten Mode. It’s the sweet spot for coins and EXP. Not too hard, decent rewards. You can solo it with Sniper spam if you’re patient.
Complete Daily Quests. Four daily quests reset every 24 hours. Easy coins and gems.
Login Rewards. Just logging in daily gives you free stuff. Don’t skip days.
Playtime Rewards. Six chests unlock based on time played. More chests if you watch ads.
Achievements. One-time rewards for completing specific tasks. Check the Index menu.
