FAQ

Common questions about Dino odds

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

The current obtainable Dino 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 Dino calculator?

The real-time calculator does not simulate endless duplicate loops. Instead, it uses a precomputed effective cost for the Dino 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 Dino 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 Dino Pack is 5.83%.

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

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