❓ Frequently Asked Questions
What is Server Luck?
Server luck is a multiplier (1x-5x) that affects your earnings based on current server conditions. Higher server luck means better earnings from all your brainrots.
How do Rebirths work?
Rebirths reset your progress but give permanent bonuses. Each rebirth adds 10% to earnings, increases base lock time by 10 seconds, and unlocks new items. Currently 13 rebirths are available.
What does Index Complete mean?
Completing any mutation's index (collecting every brainrot in that mutation variant) adds +0.5 to mutation multipliers and gives you a special colored base.
Can I stack mutations?
No, mutations are NOT stackable. A brainrot can only have one mutation at a time. However, traits ARE stackable and can be combined with mutations.
How do I get traits?
Regular traits (La Vacca, Bubblegum, Bombardiro) are obtained through special events that happen during gameplay. Admin traits require administrator spawning and are rarer.
What is the Bloodmoon Event?
The Bloodmoon is a special event that doubles ALL earnings (2x multiplier) when active. It's a temporary boost that significantly increases your brainrot income.
How accurate is this calculator?
This calculator uses the exact same formulas as the game. All multipliers stack multiplicatively, and the calculations match the official game mechanics for precise earnings estimates.
Tips for maximizing earnings?
Focus on higher rarity brainrots, complete mutation indexes for +0.5 bonuses, stack multiple traits when possible, and time your purchases during high server luck periods. Check out our scripts page for automation tools.
