FAQ

Common questions about Bug odds

What are the odds of a Chroma in the Bug Pack?

Using the current community-referenced Bug Pack table, each box has a 0.03% Chroma rate. At 500 tokens with duplicate refunds off, the exact chance of at least one Chroma is 0.60%.

How does dupe refund work in this Bug calculator?

The real-time calculator does not simulate endless duplicate loops. Instead, it uses a precomputed effective cost for the Bug Pack. That effective cost is the pack price minus the exact average sell-back value from the current pack table, which keeps calculations instant while still reflecting duplicate refunds.

What are the odds of at least one Legendary from the Bug Pack?

This calculator uses exact binomial math, not guesses. At 500 tokens with duplicate refunds off, the chance of at least one Legendary from the Bug Pack is 9.54%.

Does the Bug Pack calculator use simulation for the main odds?

No. The headline probabilities for the Bug Pack update instantaneously using the exact formula P(at least 1 success) = 1 - (1 - p)^n, where p is each Bug blook's drop rate and n is your pull count (20 pulls per 500 tokens). Full Monte Carlo simulation only runs when you click the simulate button.
