Tower Defense Simulator has 2 working codes right now: 2MILLION (Mercenary skin for the Pursuit) and 1MILCOMMUNITY (Community skin for the Shotgunner). There is no new Halloween code yet. The game’s Halloween 2026 event is called Solar Requiem, and its final chapter, Night IV, is live until November 6 at 17:00 UTC. TDS is also one of the side-quest games in Roblox’s The Hollow event, which pays tickets until November 2.
Codes checked October 31, 2026, 16:25 UTC against the official game description and five dated code trackers.

Quick answer
- Working Tower Defense Simulator codes: 2MILLION and 1MILCOMMUNITY. Both are skin codes, so you must already own the tower.
- Official proof: Paradoxum Games’ Roblox game page says “Use code 2MILLION for a free Mercenary Pursuit skin!”
- New or Halloween code: none so far. No tracker we checked lists a Solar Requiem code.
- Halloween event: Solar Requiem Night IV started Oct 30 at 16:00 UTC and is listed until Nov 6 at 17:00 UTC (12:00 PM EST, 9:00 AM PST).
- The Hollow quest: win Solar Requiem Night 1 on Easy, then claim your tickets back in The Hollow before Nov 2, 20:00 UTC.
- Free bonus without a code: join the Paradoxum Games group for +$100 starting cash in matches.
Working Tower Defense Simulator codes (October 31, 2026)
We only list a code as working if the developer posted it or at least two dated trackers show it as active. Both codes below pass that test.
| Code | Reward | You need | Added | Status (checked Oct 31, 16:25 UTC) |
|---|---|---|---|---|
| 2MILLION | Mercenary skin (Pursuit) | The Pursuit tower | June 2026 (2 million likes) | Working: on the official game page, plus Roblox Den, Destructoid, Bloxodes, Dexerto and Pocket Tactics |
| 1MILCOMMUNITY | Community skin (Shotgunner) | The Shotgunner tower | June 2026 | Working: Roblox Den, Destructoid, Bloxodes, Dexerto, Pocket Tactics and the TDS wiki |
The freshest checks came from Roblox Den (reviewed Oct 31 at 14:03 UTC), Bloxodes (checked Oct 31) and Destructoid (updated Oct 30). Dexerto (Sep 15) and Pocket Tactics (Aug 21) list the same two codes. Destructoid describes 2MILLION’s reward as a crate. The developer’s own text says it’s the Mercenary Pursuit skin, so we go with that.

The catch: you need the tower first
Both codes are skin codes. The TDS wiki says a skin code won’t redeem unless you already own that tower. What to do first:
- 1MILCOMMUNITY is the easy one. The Shotgunner is an early tower. The wiki lists it at 850 coins. Buy it, then redeem.
- 2MILLION takes longer. The wiki’s Pursuit page lists it at 15,000 coins or 1,500 Robux, with a Level 100 requirement. If you don’t have it yet, save the code for later. No expiry date has been announced.
Unconfirmed and old codes (don’t count on these)
Some code sites still show these codes. None of them meet our two-source rule:
| Code | Listed reward | What we found |
|---|---|---|
| ROBLOXD1ED | Premium crate | Roblox Den marks it “check” (unconfirmed). The wiki dates it to May 2021, with a 40,000-use limit, and lists it as expired. |
| COMMUNITY20 | Community Minigunner skin | Roblox Den: “check”. Wiki: expired (May 2021). |
| SubToSageProdigy | Coins | Only Roblox Den lists it, as “check”. It’s not in the wiki’s code record. Treat it as unconfirmed. |
Expired Tower Defense Simulator codes
These no longer work, according to the TDS wiki, Destructoid and Pocket Tactics. They show what Paradoxum usually gives out:
| Code | Reward | Released |
|---|---|---|
| CHRISTMAS2025 | Christmas 2025 Crate | Dec 25, 2025 |
| NOTESLA? | Premium Crate | Sep 15, 2025 |
| 4BVisits | Premium Crate | May 14, 2025 |
| EnterCodeHere | Coin Crate | Apr 1, 2025 |
| 1POINT7MIL | Vendor skin (Farm) | Mar 19, 2025 |
| MERRY2024 | Cookie Scout + Holiday Crate | Dec 25, 2024 |
| TDS5YEARS! | Party Crate | Jun 5, 2024 |
| IMCONSUMING | Mid Grade Crate | May 10, 2024 |
| MERRYXMAS2023 | Deluxe Crate | Dec 24, 2023 |
| HAPPYHALLOWEEN | Halloween Crate (48 hours) | Oct 31, 2023 |
When do new TDS codes usually drop?
The wiki’s record shows a clear pattern:
- Milestones: like-count and visit milestones (2MILLION, 1POINT7MIL, 4BVisits).
- Christmas: a code every December 24-25 for five years running (MERRY2021 through CHRISTMAS2025).
- Halloween: rare. The only Halloween code in the record is HAPPYHALLOWEEN from 2023, and none appeared in 2024 or 2025.
Going by that record, a Halloween 2026 code would be unusual, and Christmas is the most regular drop. The game has about 2.09 million likes (2,087,200 on the Roblox votes API at our check), and the description doesn’t announce a next milestone code.
How to redeem Tower Defense Simulator codes
- Open Tower Defense Simulator and go to the lobby, where the code box lives.
- Press the Codes button at the top right of the screen. Pocket Tactics, Dexerto and the wiki all put it there. Some older guides show a Twitter-bird button instead.
- Type or paste the code exactly as written, including the “?” or “!” some codes carry. Destructoid advises matching its list letter for letter.
- Press Redeem.
Code not working? Check that you own the tower, check the spelling, and make sure you’re in the lobby. If all three are fine, the code has probably expired. Paradoxum doesn’t announce expiry dates.
Is there a Tower Defense Simulator Halloween event in 2026?
Yes. Paradoxum’s Halloween 2026 event is Solar Requiem, a four-night story event about Umbra and the Penumbras. These are the official listings on the game’s Roblox events page (times in UTC):
| Chapter | Listing window (UTC) | What it added (official) |
|---|---|---|
| Night I | Oct 9, 16:00 to Oct 16, 16:00 | Event start. Battle Pass with 10+ skins, 5+ charms, 5+ emotes; 2 themed crates during October |
| Night II | Oct 16, 16:00 to Oct 23, 16:00 | New map and “bespoke scoring” |
| Night III | Oct 23, 16:00 to Oct 30, 16:00 | Hollow Crate (per the game description) |
| Night IV (now) | Oct 30, 16:00 to Nov 6, 17:00 | “The final night.” New tower: Star Cannon (game description) |
| Next: Time Dilator | Nov 6, 17:00 to Nov 13, 17:00 | New Hardcore AOE tower that speeds up or slows anything in its field |
Night IV’s listing ends at 12:00 PM EST / 9:00 AM PST on Friday, November 6 (US clocks fall back on November 1). The fan wiki says the whole event is scheduled to run until November 19, but Paradoxum hasn’t confirmed that date. The listing windows above are the official ones. Night 1 is still the entry point: each night unlocks the next (Night 2 shows “Complete Night 1 to unlock,” according to All Things How).

Solar Requiem badges: how many players finished each night
The game’s official badges show the event gets much harder each night. Award counts are from the Roblox badges API at 16:25 UTC on Oct 31:
| Badge | Task | Players awarded |
|---|---|---|
| Solar Requiem: Night I (Easy) | Complete Night 1 on Easy | 871,436 |
| Solar Requiem: Night II (Easy) | Complete Night 2 on Easy | 307,987 |
| Solar Requiem: Night III (Easy) | Complete Night 3 on Easy | 209,599 |
| Solar Requiem: Night IV (Easy) | Complete Night 4 on Easy | 44,712 |
| Solar Requiem: Night IV (Hard) | Complete Night 4 on Hard | 11,768 |
| Solar Requiem | All 4 nights in a row on Hard, one loadout, no restarts | 533 |
What to do first: clear Nights 1 to 3 on Easy so Night IV is unlocked before November 6. Then try Hard for the extra badges. Leave the 4-in-a-row badge for last. It needs a single loadout that can handle all four nights.
Tower Defense Simulator The Hollow quest: how to get the tickets
Roblox’s The Hollow event includes TDS as one of its “Outskirts” side-quest games, according to the Roblox wiki. Outskirts quests give tickets instead of a free item. All Things How tested the route:
- In The Hollow, click the ticket counter at the bottom left, choose Visit Games and pick the Tower Defense Simulator tile. Going in this way makes TDS show its Solar Requiem pop-up with The Hollow logo.
- Press “Let’s Go!”, skip the cutscene if you like, press PLAY and choose Night 1 on Easy. All Things How picked a Quad squad, which carried a brand-new account through.
- Survive all 15 waves and beat the boss, Penumbras. All Things How lists it at 16,500 HP. The win earns the “Solar Requiem: Night I (Easy)” badge.
- Rejoin The Hollow. The REDEEM BADGES panel shows that badge. Press Confirm.
How many tickets? The Visit Games pop-up promises 20. All Things How was paid 40 in the redeem panel on October 24. The Roblox wiki explains why: Outskirts games pay 20 extra on their featured day. Either way, The Hollow’s rewards can only be collected until November 2 at 20:00 UTC (3:00 PM EST, noon PST), according to Roblox’s newsroom. Our Roblox Halloween event end dates list has every other deadline.
Free starting cash without a code
The game description offers one permanent bonus: join the Paradoxum Games group for +$100 starting cash. It’s useful in the opening waves of Night IV.

FAQ
Are there new Tower Defense Simulator codes?
No. The newest working codes are 1MILCOMMUNITY and 2MILLION, both from June 2026. No new code had appeared on the official game page or any tracker we checked as of October 31, 16:25 UTC.
Is there a Tower Defense Simulator Halloween code?
Not in 2026 so far. Paradoxum’s only Halloween code in the wiki’s record is HAPPYHALLOWEEN (October 31, 2023), and it lasted 48 hours.
When does Solar Requiem end in TDS?
Night IV, the final night, is listed until November 6 at 17:00 UTC, and the Time Dilator update follows right after. The fan wiki gives November 19 as the event’s end, but that isn’t confirmed by Paradoxum.
Why does 2MILLION say it can’t be redeemed?
You most likely don’t own the Pursuit tower yet. Skin codes only work for towers you already have.
