Complete Fuse Machine Analysis: Probability Distribution & Fusion Strategy Guide (Deprecated)

Deep dive into Fuse Machine mechanics with comprehensive probability analysis and strategic recommendations for obtaining desired fusion brainrots

⚠️ Important Notice: This guide is now deprecated as the Fuse Machine mechanics have been significantly changed. The probability distributions and fusion strategies described below may no longer be accurate. Please refer to the latest game documentation or community guides for current mechanics.

Introduction

The Fuse Machine in Steal a Brainrot is a newly added system where players combine up to 4 brainrots to create new, potentially more valuable characters. Understanding the Fuse Machine mechanics and probability distributions is crucial for maximizing your chances of obtaining high-tier brainrots.

Time Tiers

Fusion time is divided into fixed time tiers:

• 15 minutes: Lowest tier combinations
• 30 minutes: Mid-tier combinations
• 1 hour 30 minutes: Highest tier combinations
