If you're new or just forgot where the button is hidden, redeeming your rewards in Slime RNG doesn't require any special level—just make sure you've finished the short tutorial. Follow these steps:

1. Launch Slime RNG on your Roblox account.
2. From the main screen, click the Shop button located on the right menu.

How to maximize your Slime RNG code rewards

Now that you've claimed your free Luck Boosts and Roll Speed Boosts, it's important to use them at the right time. Unlike pure idle games where you can just leave the game running overnight, popping a luck potion means you need to actively roll to get your maximum value.

• Luck Boosts: Temporarily increase your base chance to roll higher rarity slimes. Try to stack this buff when server-wide luck events are happening.
• Roll Speed Boosts: Significantly reduce the cooldown timer between individual rolls, allowing you to cram more chances into your luck window.
• Apples and Coins: Use apples for early-game crafting recipes, and coins to unlock beginner storage or simple aura upgrades.

RNG games require you to keep making moves. Use your boosts wisely when you're actively playing at the keyboard. Make sure you don't activate your potions right before logging off, as the timers will continue to count down.

If the game ever tells you an active code is invalid, double-check for typos. It's always best to just copy and paste them directly. Good luck rolling for that legendary slime!
