Beginner's Guide & Basics

Everything you need to know to start your Slime RNG journey. Master the basics, dominate the leaderboards.

Welcome to Slime RNG

Slime RNG is an incremental simulator on Roblox where you roll for slimes, build a combat team, earn coins, and prestige to become infinitely stronger. The core loop is simple but mastering it requires strategic thinking.

Core Gameplay Loop

The fundamental cycle in Slime RNG consists of:

  1. Roll for Slimes - Spend coins to roll new slimes with varying rarities
  2. Deploy Your Team - Your rolled slimes automatically fight enemies in the current zone
  3. Earn Currency - Defeat enemies to earn Coins and (later) Goop
  4. Upgrade - Spend currency on upgrades that increase your power
  5. Rebirth - Reset with permanent multipliers to grow even stronger

Currency System

Slime RNG operates on a dual-currency system:

Coins (Primary Currency)

Coins are the foundation of your early game. You earn them by defeating enemies, and they scale exponentially as you progress through zones. Coins are used for:

  • Rolling for new slimes
  • Buying upgrades (Auto Roll, Roll Speed, Enemy Count)
  • Unlocking new zones
  • Unlocking the Goop mechanic (requires 10 million coins)

Goop (Prestige Currency)

Goop is the key to becoming truly powerful. Unlike coins, Goop is deflationary and rare. You only unlock the ability to earn Goop after investing 10 million coins. Goop is used exclusively for Rebirthing - the prestige mechanic that permanently boosts your stats.

Important:

To unlock Goop drops, you must first spend exactly 10,000,000 coins. This is the primary mid-game bottleneck. Focus all early-game capital on reaching this threshold as quickly as possible.

First Hour Guide

Follow this optimized path for your first hour of gameplay:

Minutes 1-5: Initial Setup

  1. Roll a few times to get some basic slimes
  2. Equip your best slimes to your combat team
  3. Look for Fin slime - it's the best early-game damage dealer

Minutes 5-15: First Upgrades

  1. Buy Auto Roll (200 coins) - This is mandatory. It automates the rolling loop so you can focus on strategy.
  2. Upgrade Roll Speed using Dice currency - More rolls = more chances at rare slimes
  3. Buy Next Zone - Move to Zone 2 for better coin yields

Minutes 15-60: Building Momentum

  1. Focus on accumulating coins as fast as possible
  2. Prioritize Enemy Count upgrades - doubling enemies doubles your income
  3. Feed fruits (Apples, Cherries, Carrots, Bananas) to your best slimes for XP
  4. Don't invest heavily in Luck yet - Income > Luck until you can farm 10M coins

Your First Rebirth

Once you've unlocked Goop and farmed enough, you can execute your first rebirth. Here's what happens:

  • Your coin balance resets to zero
  • All zones are locked again
  • BUT you keep: All slimes, all fruits/consumables, all upgrades, and a permanent luck multiplier boost

The luck multiplier from rebirthing is massive - players often see jumps from 65x to 98x multiplier in a single rebirth. This makes each subsequent run dramatically faster.

Understanding Slime Variants

When you roll a slime, there are three possible outcomes:

  • Standard Slime - Normal stats based on the slime type
  • Shiny Variant - 1 in 500,000 chance. Enhanced stats, unique visual aura
  • Huge Variant - 1 in 1,000,000 chance. Massive damage multiplier, expanded AoE, top-tier choice
  • Huge Shiny - Combination of both. The rarest and most powerful slimes in the game
