As of right now, there are 33 **Slime RNG Zones** to unlock. With each zone, the cost to unlock them increases, in exchange for more Goop to Rebirth in [Slime RNG](https://www.roblox.com/games/92416421522960/Slime-RNG) and higher Zone Luck. Across the zones, you can find slime recipes; we’ve got a [Slime RNG Recipe Locations](https://www.gamezebo.com/walkthroughs/slime-rng-recipe-locations/) guide to help.
## How I Unlocked All Slime RNG Zones
It takes a lot of patience and perseverance, but it’s entirely possible to unlock all 33 of the Slime RNG zones in one go (more or less). I recommend investing in your Coin Income and Overkill upgrades first and foremost.
Rebirthing is important for your Luck stat, but it removes all your coins, making you start from scratch. As you progress through each zone, the Zone Luck increases, and so does the amount of [Goop](https://www.gamezebo.com/walkthroughs/how-to-get-goop-in-slime-rng/) you get when defeating slimes.
