FAQ

Common questions about Aquatic odds

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

The current obtainable Aquatic Pack lineup does not include a pack Chroma, so the calculator returns 0% Chroma odds for this pack right now.

How does dupe refund work in this Aquatic calculator?

The real-time calculator does not simulate endless duplicate loops. Instead, it uses a precomputed effective cost for the Aquatic 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 Aquatic 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 Aquatic Pack is 16.1%.

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.
