FAQ

Common questions about Spooky odds

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

Using the current community-referenced Spooky Pack table, each box has a 0.06% Chroma rate. At 500 tokens with duplicate refunds off, the exact chance of at least one Chroma is 1.19%.

How does dupe refund work in this Spooky calculator?

The real-time calculator does not simulate endless duplicate loops. Instead, it uses a precomputed effective cost for the Spooky 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 Spooky 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 Spooky Pack is 12.2%.

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

No. The headline probabilities for the Spooky Pack update instantaneously using the exact formula P(at least 1 success) = 1 - (1 - p)^n, where p is each Spooky 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.
