Brawl Stars Coffin Box Skins has been updated to use Supercell’s official Brawloween 2026 Coffin Box table. The key correction is simple: every Coffin Box contains 10 rewards and Supercell guarantees at least one premium reward in each box. That official structure replaces the launch-day estimates and third-party odds that circulated before Supercell published its own support table.
For Brawl Stars Coffin Box Skins, the official table finally separates normal rarity skin rolls from the Brawl-o-ween premium skin reward. The official percentages are listed per draw, while the premium guarantee changes how a whole box should be interpreted. That means old nine-draw descriptions, unofficial percentages and whole-box calculations based on ten identical independent rolls should no longer be treated as current.

Supercell lists standard skin chances of 0.87% for a Random Rare Skin, 0.17% for Super Rare, 0.13% for Epic, 0.09% for Mythic and 0.04% for Legendary on a draw.
Brawl-o-ween Skins are listed separately as a Premium Reward at 0.61% per draw. Because every Coffin Box guarantees at least one premium reward, the premium mechanic matters when judging whether a box can still be good without a standard skin roll.
A guaranteed premium reward is not the same as a guaranteed Brawl-o-ween skin. The premium pool also contains Coins, Power Points, Gems, Hypercharges and Buffies, so a box can satisfy its premium guarantee without producing a cosmetic.
| Reward or rule | Official value |
|---|---|
| Random Rare Skin | 0.87% |
| Random Super Rare Skin | 0.17% |
| Random Epic Skin | 0.13% |
| Random Mythic Skin | 0.09% |
| Random Legendary Skin | 0.04% |
| Brawl-o-ween Skin (Premium) | 0.61% |
How Brawl Stars Coffin Box Skins works with the premium guarantee
The most important change for Brawl Stars Coffin Box Skins is the guaranteed premium reward. Supercell does not say that every reward slot uses the same pool with the same independent rules. Instead, its support page explicitly separates several outcomes as Premium Rewards and says every Coffin Box contains at least one premium reward.
The premium entries currently shown are Brawl-o-ween Skins at 0.61% per draw, 1000 Coins at 0.52%, 1000 Power Points at 0.52%, Random Hypercharge at 0.04%, Random Buffie at 0.09% and 10 Gems at 0.44%. Those figures should be quoted as Supercell publishes them rather than converted into an invented guarantee for one exact premium item.
That distinction keeps Brawl Stars Coffin Box Skins useful. A player can know a premium result is guaranteed without being promised a skin, Brawler or upgrade that the official rules do not guarantee. It also explains why two valid Coffin Boxes can look very different even though both satisfy the same premium rule.
Standard rewards still make up most of the table
Outside the premium guarantee, Brawl Stars Coffin Box Skins sits inside a broad standard reward pool. The most common individual entries include 50 Coins and 50 Power Points at 15.88% each, 100 XP Doublers at 13.05%, 20 Bling at 8.70%, 100 Coins and 100 Power Points at 7.83% each, and 30 Credits at 6.52%.
Rarer progression and account unlocks sit much lower. Random Gadget is 0.44%, Random Star Power is 0.22%, Random Hypercharge is 0.09% and Random Buffie is 0.09%. Brawler chances are 0.30% for Epic, 0.13% for Mythic and 0.04% for Legendary. These are official per-draw values, not a prediction of what one complete box must contain.
For Brawl Stars Coffin Box Skins, common resources should therefore be treated as normal results rather than evidence that a box is broken. The guaranteed premium reward adds a floor to the opening, but the remaining results can still be weighted heavily toward Coins, Power Points, XP Doublers, Credits and Bling.
Owned rewards and fallback rewards
Supercell also adds an ownership rule that matters for Brawl Stars Coffin Box Skins: you cannot receive a reward you already own. If the selected reward cannot be granted because it is already on the account, the game gives a fallback reward of Bling, Coins or Credits instead.
That can make screenshots difficult to compare. One account may display the named cosmetic or unlock while another shows a currency fallback from the same underlying reward category. A fallback is not an extra eleventh reward and should not be counted as a second independent draw.
Why older Coffin Box odds should be ignored
Before Supercell published the official page, Brawl Stars Coffin Box Skins coverage had to rely on incomplete live data and third-party tables. That is no longer necessary. The official support portal now gives the reward count, premium guarantee and exact chance-per-draw values, so those numbers should override earlier estimates.
In particular, any reference to nine rewards per box is outdated. The current official wording is 10 rewards. Old rates such as the previously circulated 0.1059% Hypercharge estimate are also obsolete; Supercell now lists Random Hypercharge at 0.09% in the standard table and 0.04% as a Premium Reward.
Going forward, Brawl Stars Coffin Box Skins should be checked against the live Supercell support table whenever the event changes. Brawloween is a live event, so an official revision should replace an older number rather than be averaged together with it.
Brawl Stars Coffin Box Skins: quick answer
The current answer for Brawl Stars Coffin Box Skins is based on Supercell’s official table: a Coffin Box contains 10 rewards, at least one reward is guaranteed to come from the premium pool, and the published percentages are chances per draw. The premium guarantee does not promise one exact skin or upgrade, and owned rewards can fall back to Bling, Coins or Credits.
If you are checking Brawl Stars Coffin Box Skins after seeing an older guide, use the official values above and ignore previous nine-draw wording or third-party estimates. That keeps the page aligned with the live Brawloween 2026 reward system rather than its launch-day uncertainty.
