This page gives the exact odds for each booster. The figures are read from the game settings when the page is displayed: they’re the ones the draw applies.
Draws made on our servers
All draws are made on our servers, with a cryptographic random number generator. Your device chooses nothing: it only receives the result once the opening is recorded.
GOTY booster
5 cards per booster. Each slot draws its rarity according to the weights below, independently of the others.
Guarantee: at least one Uncommon or better in every booster. If no slot reaches that rarity, which happens in 3.20391% of boosters, the last slot is redrawn among the guaranteed rarities, at their relative weights. The other slots don’t change.
| Rarity | Weight per slot | Rate per card, guarantee included |
|---|---|---|
| Common | 50.25% | 49.609218% |
| Uncommon | 25.14% | 25.463804% |
| Rare | 16.59% | 16.80368% |
| Epic | 6.13% | 6.208955% |
| Ultra Rare | 1.3% | 1.316744% |
| Legendary | 0.5% | 0.50644% |
| Mythic | 0.09% | 0.091159% |
Odds per booster
- At least one Epic or better
- 34.68%
- At least one Legendary or better
- 2.95%
Guarantee included, not counting pity.
Within the drawn rarity, the card is picked with equal probability among the cards of that rarity the booster can contain. A booster never contains the same card twice. If a rarity has no cards, the slot takes the nearest lower rarity that has some, never a higher one; a booster that cannot fill its slots that way does not open.
Nintendo, PlayStation, Xbox, PC, Retro and Arcade, and Mobile boosters
Nintendo · PlayStation · Xbox · PC · Retro and Arcade · Mobile: the same number of cards, the same guarantee and the same rates.
5 cards per booster. Each slot draws its rarity according to the weights below, independently of the others.
Each of these boosters only draws from its own card family. Rarity rates are the same; within a family, a specific card comes up more often than in the whole theme.
Guarantee: at least one Uncommon or better in every booster. If no slot reaches that rarity, which happens in 3.20391% of boosters, the last slot is redrawn among the guaranteed rarities, at their relative weights. The other slots don’t change.

If a rarity has no cards, the slot takes the nearest lower rarity that has some, never a higher one; a booster that cannot fill its slots that way does not open.
Pity
Each player has one counter per booster, counted in boosters opened since the last booster that contained a Legendary or better.
On the 100th booster in a row without a Legendary or better, a Legendary is guaranteed.
The guaranteed card takes the place of the lowest-rarity card in the booster.
“Or better” counts: a Mythic also resets the counter.
Pity can only improve a booster. Your counter is shown on the boosters page once you’re signed in.
Variants
- Gold and silver: among cards of Epic or Ultra Rare rarity drawn from a booster, 1% come out silver; among those of Legendary or Mythic rarity, 1.5% come out gold. A card of a lower rarity never has a finish.
A crafted copy is never gold or silver.
Golden booster
The golden booster is a reward: you earn it with your third Battle win of the day, at each album milestone, and every ten levels. It draws from the same cards as its theme’s booster. Nothing below Rare goes in: the remaining rarities share the space, each in proportion to its weight. It leaves the rarity guarantee alone: it does not count towards boosters opened in a row, never triggers the guarantee and never resets it.
| Rarity | Published weight | Rate per card |
|---|---|---|
| Common | 0% | 0% |
| Uncommon | 0% | 0% |
| Rare | 67.43% | 67.43% |
| Epic | 24.9% | 24.9% |
| Ultra Rare | 5.28% | 5.28% |
| Legendary | 2.03% | 2.03% |
| Mythic | 0.36% | 0.36% |
Legendary booster
One booster in 1,000 becomes legendary when it’s opened, that is 0.1%. Nothing sets it apart beforehand: the draw happens on the server, the moment you open it. This applies to stock, reward and golden boosters, not to tutorial ones.
A legendary booster contains as many cards as a regular booster, all Ultra Rare or better. One of them is a guaranteed Mythic; each of the others is Ultra Rare at 70%, Legendary at 25% and Mythic at 5%. The card is then picked as in any booster, and gold and silver finishes are added at the same rates.
Tutorial boosters
On your first sign-in, you get 3 free boosters, outside your stock. The first 2 guarantee a card of Epic rarity or better, the last one a card of Ultra Rare rarity or better, through the same mechanism as the regular guarantee.
