What is Slime RNG?
Slime RNG is an incremental gacha simulator on Roblox by Stouts Studio. You roll for slimes, upgrade them, fight enemies for Goop, unlock new worlds, and rebirth for permanent luck boosts — a loop that has pulled over 295 million visits and a steady 200K+ concurrent players since launching in February 2026.
Unlike grind-only simulators, Slime RNG rewards luck-stacking strategy: liking the game, joining the Stouts Studio group, bringing friends, and rebirthing all multiply your effective luck. That's why a calculator and a rebirth decision table matter more than a generic codes list.
This site is built specifically for Slime RNG — codes verified against the official Discord, rarity index synced with player screenshots, and a calculator no other guide site offers.
How to start playing Slime RNG
Three steps in your first hour — skip nothing, the early luck stacks matter.
Open Slime RNG in Roblox
Launch Slime RNG directly: play on Roblox. On your first server, like and favorite the game and join the Stouts Studio group — both give permanent +luck bonuses you'll want before your first rebirth.
Redeem all active codes
Open /codes and redeem every active code listed (expired codes are kept below for reference). Free luck potions, coins, and Ultra Luck boosts stack — claim before you spend any of them. New codes drop in Discord most weeks.
Plan your first rebirth with the calculator
Before grinding to your first rebirth, open the Luck Calculator and the Rebirth Guide. Knowing your effective luck multiplier saves hours of wasted rolls.
Why players trust this site
Three things every other guide skips.
Discord-verified codes
Every active code is checked against Stouts Studio's official Discord (#announcements + #codes) before it lands on /codes. Each code shows its verified-on date so you can spot stale lists at a glance — IGN and Eurogamer pages update monthly, ours refreshes weekly.
Single-game depth
Multi-game guide hubs cover 200+ Roblox games shallowly. We cover one — Slime RNG — across 11 dedicated pages: codes, luck guide, calculator, rebirth, slime list, recipes, goop farming, tips, and a real beginner walkthrough. No filler from unrelated games.
Calculator-first design
Slime RNG is a luck-stacking game and players ask 'is one more rebirth worth it?' constantly. We built the only single-game luck multiplier + rebirth break-even calculator. Plug in your boosts, see the actual numbers — no other guide site offers this.
