To increase Luck in Slime RNG, players must unlock Luck-related Upgrades, play with friends, unlock multiple zones, collect all variations of slime, and consume Luck potions.
In Slime RNG, the core objective is to collect rare/secret slimes, which can then be used to defeat powerful monsters. For this, you need a lot of luck stat, which can be obtained in a wide variety of ways. So, here is a detailed guide explaining all the ways to improve your base Luck stat in Slime RNG to get the best Slimes.
What are the various ways to improve Luck in Slime RNG?
Below, you can find all the ways to improve Luck in Slime RNG.
Slime Index Completion

If you open the Slime Index on the right side of the page, you can find the list of all the collectible Slimes in the game. Each time you craft a new Slime or roll it for the first time, you will get a +5% Luck boost along with other cool rewards like food items, coins & more. So, try rolling for new Slimes to increase your Luck slowly.
Luck Upgrades

If you open the Upgrades menu, you can find the entire left half of the page with exclusive upgrades just for improving your Luck. It starts with the Luck I upgrade and goes all the way to the Supreme Luck III. Ensure to spend enough money on these upgrades as you progress through the game. Each of these upgrades almost doubles your Luck.
Rebirth

Rebirthing is one of the most straightforward ways to improve your Luck in Slime RNG. Each time you hit the Rebirth button, your Luck stat will nearly double. So, just ensure you farm enough Goop required for your next Rebirth to make the most of it.
Like the Game & Join the Group
Liking the Slime RNG game and joining the Stouts Studio will provide the players with a permanent +1 Luck Boost. This is pretty easy: just hit the like button before joining the game, then click the link to join the group.
Friends Boost
Slime RNG is a social game, and the developers have added a feature that provides extra Luck if you play with your friends. This is a stackable bonus that increases as you play with more friends on the same server. Ensure that the Friendly Boost and Friendly Luck upgrades are being purchased to make the most of the Friend Boost feature. Also, I suggest using a Slime RNG private server to make it easier to play with friends.
Luck Potions

Luck Potions are an integral part of Slime RNG, and you can always consume them to increase your Luck ratings in the game temporarily.
- Luck Potion: Doubles Luck for 3 minutes.
- Ultra Luck Potion: Triples Luck for 3 minutes.
Zones & Map
Each Zone or map you unlock in Slime RNG provides a +1 Luck to your overall rating. So, if you have opened 6 areas or zones, you will have +6 Luck. Try to earn as much money as possible and open as many zones as you can. Remember, if you rebirth, you will lose all of your Luck ratings and have to start from 0.
Admin Events & Server Luck
Each weekend, the Slime RNG developers conduct an Admin Event inside the game each Saturday at 6:00 PM BST. During these Events, the developers increase the Server Luck by several fold, allowing you to get the rarest and the best Slimes in the game with ease. So, participate in the event by bookmarking our Slime RNG Admin Abuse Event guide.
Premium Luck Gamepasses
You can always purchase multiple Luck-related gamepass items from the store to further scale the factor. As of now, there are two Gamepasses that help permanently improve Luck, and you can find details about them below.
- Lucky Rolls: This 30 Robux item permanently increases your Luck by +1.
- VIP: Pay 150 Robux to become a VIP to enjoy benefits like increased walk speed, 10% coin income, 10% Coin Income & 0.5 Luck.
