What is Luck?
Luck is the core stat that determines your odds of rolling rare slimes. Higher Luck directly improves your chances for Huge (0.1%), Shiny (0.4%), and Inverted (0.04%) variants.
Luck combines multiple bonuses into one multiplier. Every source stacks together, so the goal is to activate as many as possible before rolling.

Rebirth System
Rebirth is the MOST POWERFUL long-term method. Each rebirth nearly doubles your Luck stat (~2x multiplier).
How Rebirth Works
- 1Save GoopRebirth costs double each time (first is cheap, later ones need millions)
- 2Press Rebirth ButtonResets your progress but gives permanent Luck multiplier
- 3Rebuild FasterYour higher Luck helps you progress faster each rebirth
- 4RepeatNo maximum rebirth level - keep going for exponential growth
Each rebirth ~2x Luck means: Rebirth 5 = 32x total, Rebirth 10 = 1,024x total, Rebirth 20 = over 1 million times your starting luck.
Luck Upgrades
Upgrade progression: Luck I → Luck II → Luck III → Supreme Luck I → Supreme Luck II → Supreme Luck III. Each upgrade nearly doubles your Luck.
- •Buy upgrades in order (you must complete earlier tiers first)
- •Each upgrade costs Goop (price increases with tier)
- •Effects are permanent (never reset, even after rebirth)
- •Supreme Luck III is the final upgrade tier
