Slime Card Collection is a Roblox collecting game built around one very satisfying loop: buy elemental booster packs, hatch them into slime cards, and watch every card in your binder earn you cash every second. There are more than 160 slime cards to hunt down across the elemental packs, and the rarest pulls take serious luck, so filling out the binder is a long-term project. You can also trade cards with other players, send your best cards off for PSA grading, and keep earning money while you are offline.
Because packs get expensive fast, codes are one of the easiest ways to speed everything up. The developers hand out free Plerts potions, which temporarily boost how much cash your cards produce, plus InstaHatch tokens that open packs instantly. Below you will find every Slime Card Collection code we could verify as working right now, the expired list, and the exact steps to redeem them in the game.
All New Slime Card Collection Codes
- SPECIAL: Free potions (==NEW==)
- BOSSBATTLE: Free potions
- Halloween: Free potions
- Royal: Free potions
- Gemstone: 1 Superplets Potion
- BugPack: 1 Superplets Potion

- Quest: 5 Plerts Potions

A quick tip before you start spending: drink your Plerts potions right before a big pack-buying session rather than the moment you redeem them. The boost only lasts a short time, so activating it when your binder is full of freshly hatched cards means every second of the boost is earning at your highest possible rate.

How to Get More Slime Card Collection Codes
New codes for this game usually arrive alongside updates, events and community milestones, and the developers announce them first in the game’s official Discord server, so that is the fastest place to spot a fresh drop. Joining the Idle Workers Roblox group is also worth doing, since the team posts game news there. Either way, bookmark this page and check back often — we re-verify the list regularly and add new codes here as soon as they are confirmed working.
Why Are My Slime Card Collection Codes Not Working?
Double-Check for Typos: These codes are case-sensitive, and several of them mix capital and lowercase letters in ways that are easy to mistype, like EquipmentShop and OnlineRewards. Copy and paste each code straight from the list above instead of typing it out by hand.
The Code Has Expired: Codes in this game tend to rotate out quietly when a new batch arrives, and the developers do not always announce when an old one stops working. If a code from another site fails, compare it with our verified list — anything we no longer show as active has most likely been retired.
You Have Already Redeemed It: Every code can only be claimed once per account. If you redeemed a code in an earlier session, the game will reject it the second time, so work through the list and skip any you have used before.

Conclusion
That is every verified Slime Card Collection code for now — 18 working codes worth of free potions and hatch tokens to help you crack open more packs and complete that binder faster. Redeem them sooner rather than later, since codes here can disappear without warning, and swing back whenever a new update lands to catch the next batch.
