How Multipliers Work

Multiplier Calculation

The total multiplier is calculated using this formula:

Total Multiplier = Mutation Multiplier + ∑(Trait Multipliers) - (N-1)

Where N is the total number of multipliers (1 mutation + number of traits)

Example 1:

Gold Mutation (1.25x) + Taco Trait (3x)
= 1.25 + 3 - 1 = 3.25x total multiplier

Example 2:

Lava Mutation (6x) + Galactic (4x) + Fireworks (6x)
= 6 + 4 + 6 - 2 = 14x total multiplier

Tips & Strategy

  • • Focus on event mutations for higher multipliers
  • • Normal mutation is always available as a fallback
  • • Higher rarity mutations provide better income

For Traits

  • • Combine multiple traits for maximum effect
  • • Participate in admin events for rare traits
  • • Use the calculator to plan your combinations
