FAQ

Common questions about Outback odds

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

Using the current community-referenced Outback 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 Outback calculator?

The real-time calculator does not simulate endless duplicate loops. Instead, it uses a precomputed effective cost for the Outback 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 Outback 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 Outback Pack is 7.15%.

Does this tool use simulation for the main odds?

No. The headline probabilities update with the exact formula P(at least 1 success) = 1 - (1 - p)^n. Full simulation only runs when you explicitly click the simulation button, and it runs off the main thread in a web worker.
