King Legacy fruit key odds calculator (November 2026)
Enter a key’s drop chance and how many keys you open to get your odds of at least one fruit of that rarity, with the wiki’s key table one click away.
The formula
With chance p per roll and n rolls, the chance of at least one hit is 1 − (1 − p)^n. Rolls for a target chance q are ln(1 − q) ÷ ln(1 − p), rounded up. It assumes every roll is independent (no pity system).

Frequently asked questions
What are the Iridium Key odds in King Legacy?
The King Legacy wiki lists 10% Mythical, 30% Legendary, 40% Epic, 15% Rare, 4% Uncommon and 1% Common. The developer has not confirmed these numbers.
How many Copper Keys for a Mythical fruit?
At the wiki’s 0.05% per Copper Key, you would need 1,386 keys for a 50% chance and 4,605 for 90%.
Are the wiki odds official?
No. The wiki is the one the official Trello points to, but its key pages give no source and anyone can edit them. We show them as reference only.
What about the old Gacha odds?
The old Gacha (50% Common, 35% Uncommon, 14% Rare, 1% Legendary) is from a 2022 Trello card. King Legacy now uses keys, so those odds are out of date.
What are the race reroll odds?
Hector rerolls between Human, Fish, Angel and Animal for 35 Gems. The wiki says each other race has about a 33% chance because you cannot roll your current race; that is a calculation, not a published table.
