Catch a Monster Codes (Active and Expired)
Last checked September 17, 2026 (UTC)
Catch a Monster burns through codes faster than almost any Roblox game I track, so I only keep the ones that Pocket Tactics, Roblox Den and Destructoid all still show as working this week. As of today the STOWERBUG and COILRIFT drops are the ones worth logging in for.
Catch a Monster codes are the short strings Lightning Dragon Studios posts on Discord for events, new monster releases and community milestones, and they pay straight into your hatching and upgrading stash for free Tower Gems, Task Points, Dragoncoins, Mythical Chests, rare eggs, and Coin and XP potions. the whole game is a loop of catching monsters, hatching eggs for stronger companions and pushing them through tougher zones. Chests and eggs from codes skip a lot of that grind, and Tower Gems feed the tower events that hand out the best mounts. The potions matter less, but three free XP potions on a fresh team still saves a solid hour.
Quick tip. redeem the event codes the day you see them. STOWERBUG and STELLAWOLF are tied to time-limited events, and this developer retires codes without warning once the event rotates out. I have watched a Mythical Chest code go dead in under a week, so open the game, claim everything, then hatch.
Active Catch a Monster codes (12)
Every code below was still redeeming when I checked it against Pocket Tactics, Roblox Den and Destructoid this week. Claim the event ones first, they are the shortest lived of the bunch.
| Code | Reward |
|---|---|
| PVPFIX New Expires soon | 12,000 Wanderer Coins |
| CORSAIR Expires soon | 1 Mythical Chest |
| BIGOPUS Expires soon | 1 Nightmare Bloodcore Egg |
| PXPVEF Expires soon | 10 Super Pear + 3 Celestial Genesis Fruit |
| VELOROS Expires soon | 5,000 Wanderer's Coin |
| STOWERBUG Expires soon | Task Points + 2,000 Tower Gems |
| COILRIFT Expires soon | 1 Mythical Chest |
| NEXA Expires soon | Star Lantern Egg |
| STELLAWOLF Expires soon | Task Points |
| coin Expires soon | 3 Middle Coin Potions |
| xp Expires soon | 3 Small XP Potions |
| cam Expires soon | 3 Small XP Potions + 3 Small Coin Potions |
If one comes back as invalid, its event most likely rotated out. This developer does not announce retirements, so I pull dead codes the moment two trackers agree they are gone.

New Catch a Monster codes arrive with almost every update, usually named after the monster or event they celebrate. NEXA came with the Star Lantern Egg, COILRIFT with the rift update, and the pattern has held for months, so expect a fresh one whenever the game page shows a new banner. Redemption happens through the gift icon in game, no level requirement. Each code is one use per account, some are case sensitive, and the event ones close as soon as their event ends.
- Redeem in game: click the gift icon in the top-right corner.
- Payouts are chests, eggs, Tower Gems, Task Points and Coin or XP potions.
- Event codes retire without warning when the event ends, so claim them early.
- One use per account, and several codes are case sensitive.
- New ones land on the Lightning Dragon Studios Discord with nearly every update.
How to redeem Catch a Monster codes
No website and no external portal, just a gift box in the corner of the screen. Rewards land in your inventory the second you confirm.
- Open Catch a Monster on Roblox and wait for the world to load.
- Click the gift icon in the top-right corner of the screen.
- Type or paste a code into the box, matching the capitalization shown here.
- Press Redeem. Chests, eggs and potions go straight to your inventory.
Some codes here are all caps and some are all lowercase, and that is how the developer published them. If a code refuses, retype it exactly as listed before assuming it expired.
Catch a Monster codes FAQ
What do Catch a Monster codes give you?
Mostly hatching and upgrade resources. Mythical Chests, rare eggs like the Star Lantern Egg, Tower Gems for the tower events, Task Points, and small Coin or XP potions. Nothing cosmetic and no premium currency, it is all progression.
Why does my Catch a Monster code say it is invalid?
Usually because its event ended. Lightning Dragon Studios ties most codes to a monster launch or a seasonal event and switches them off when the next one starts. If the code is recent, check the capitalization, since a few of them are case sensitive.
Are the codes case sensitive?
Some are. The developer publishes event codes in capitals and the older potion codes in lowercase, and the game does not always accept the other form. Copy them exactly as they appear on this page and you will not hit the problem.
How often do new Catch a Monster codes come out?
Almost every update, which for this game means every week or two. New monsters, rift events and tower events each tend to ship with a code, so the active list changes constantly and the expired list is one of the longest on Roblox.
Where do new Catch a Monster codes appear first?
The Lightning Dragon Studios Discord, in the announcements channel, usually within minutes of an update going live. Trackers like Pocket Tactics and Roblox Den mirror them within a day, and I cross-check against those before adding anything here.
Do I need to be a certain level to redeem?
No. The gift icon is available from the first minute, so a brand new account can claim every active code before catching a single monster. That is actually the best time to do it, since the potions and chests speed up the early zones the most.
