Slime Card Collection Codes (September 2026)

Slime Card Collection is a Roblox game where you build up a yard of slimes and hatch new ones using potions and tokens. The codes below hand you free Plerts Potions, Superplets Potions, and InstaHatch Tokens without spending any Robux, so it’s worth punching them in before you buy anything from the shop.

Working Slime Card Collection Codes

Type these into the game exactly as shown below, since codes are case-sensitive and a stray space will stop them from working.

Once you’ve claimed a code, it won’t work a second time on the same account, so there’s no need to keep re-entering it.

How to redeem codes in Slime Card Collection

You won’t find a code redemption page on a website for this one. Everything happens inside the shop menu once you’re in your slime yard.

How to get more Slime Card Collection codes

New codes usually show up when the developer hits a milestone, like a follower count on social media or a big update to the slime yard. Your best bet for catching them early is to join the game’s official Discord server and follow the Roblox community group, since both are where announcements go out first.

Check back on this list every so often, since older codes get pulled once their redemption window closes and fresh ones take their place.

Are Slime Card Collection codes free to use?

Yes. Every code above is free and hands out potions or InstaHatch Tokens without costing you Robux.

Why didn’t my code work?

Double-check that you typed the code exactly as shown, including capital letters, since the redemption box is case-sensitive. A code that’s already been used on your account also won’t work again.

Grab the potions and tokens now while they’re still active, and keep an eye on the yard’s Redeem Codes section since that’s the only place they’ll ever be entered.
