Update: We found 6 new Slay a Slime codes on April 20, 2026 and added them to the list.
Slay a Slime (also known as Slime Piece Online) is a Roblox action RPG where you hunt slimes, gather materials, and craft stronger gear across multiple worlds. Active codes hand out timed stat boosts, chest keys, race rerolls, and the occasional cosmetic title, which cuts down on early grind when you stack them before a boss run or a leveling session.

How to redeem codes in Slay a Slime
You need to clear the short opening tutorial before the shop menu becomes available. After that, the redeem field sits at the bottom of the shop panel.
Step 1: Launch Slay a Slime in Roblox and finish the intro tutorial if you're a new player.
Step 2: Press the Shop button on the left side of the screen to open the shop panel.
Step 3: Scroll to the code field labeled "Type Here" near the bottom of the shop window.
Step 4: Type or paste a working code exactly as it appears, keeping all capital letters intact.
Step 5: Press Submit to claim the reward. A confirmation will appear and timed boosts will start counting down in your active effects immediately.
If a code doesn't apply, close and rejoin the game so you land on a newer server that recognizes the latest code list.
What the rewards do
Most rewards fall into a few categories. Knowing what each one affects helps you decide when to burn a code versus save it for a specific activity.
| Reward | Effect |
|---|---|
| Greater Power / +30% Power | Increases damage dealt for the duration shown. |
| Greater Luck / 2x Luck | Improves drop chances on slime kills and chest openings. |
| Superior XP / +50% EXP | Boosts experience gained from combat and quests. |
| Rare Keys / Fabled Chest Keys | Unlock chests for gear, materials, and cosmetics. |
| Race Rerolls | Reroll your character's race for different passive traits. |
| Titles (Frozen, BETA Slayer) | Cosmetic name tags shown on your character. |
Where new codes come from
New codes typically drop alongside major updates, milestone celebrations like visit or like thresholds, and seasonal events. The developer's Discord server is the fastest place to spot them, with the game's Roblox page description and the official X account posting them shortly after. Codes usually expire within a few weeks, so redeeming them quickly is the safest play.
We'll refresh this list as new codes are released and prune any that stop working.
