Randomized chest odds

These are the exact current authority-catalog chances for each active chest family. The game must show the same odds before or immediately beside any action that grants or opens a randomized chest.

How the roll works

  1. An authority-issued chest, including a verified rewarded-ad chest, has its reward chosen and permanently sealed by the authority service when it is issued.
  2. A locally earned or offline chest uses the same published odds. Depending on the game version, it is either resolved locally when opened or sealed as a non-transferable compatibility chest; in both cases its result cannot be traded or imported into the transferable authority inventory.
  3. The rarity is selected using the table below.
  4. Every eligible skin in that chest family and rarity has an equal chance of being selected.
  5. Opening an authority-issued chest reveals its sealed result. Closing, reconnecting, or retrying does not reroll it.

Each opening is independent. There is currently no pity counter, guaranteed-rarity sequence, or player luck modifier. Percentages are per chest and may not total visually beyond 100% because of displayed decimal precision.

A Mineral Chest cannot currently award a One-of-a-Kind skin, even though One-of-a-Kind Mineral skins may appear elsewhere in the catalog.

Additional independent rolls

  • Variant: Classic, Bright, Deep, and Soft are each 25%.
  • Finish: None, Speckled, Clouded, and Shimmered are each 25%.
  • Focus stat: Tap, Auto, Critical, and Anti-shield are each 25%.
  • Trait: selected uniformly from the skin's badge-based trait pool. Legendary and One-of-a-Kind rewards add one extra Proud entry to that pool, so repeated entries are intentionally weighted.

These rolls do not change which skin or rarity was awarded.

Epic skins also have an independent all-stats jackpot. The jackpot is 11.2360% of Epic Elemental rewards and 9% of Epic Mineral rewards. It forces a Perfect grade and maximum values for all four stats.

Purchases and rewarded ads

The only paid Store item is the non-random Remove Ads option when billing is available; paid purchases may be temporarily paused during release or security checks. Slime Essence pack catalog entries remain unavailable while the player Market is disabled, so players are not asked to buy currency for an unavailable trading feature. A rewarded ad may grant an Elemental Chest, so its action must link to these odds before the player chooses to watch the ad.

Changes to these odds

Odds are controlled by the versioned game catalog. A change must not be activated until the in-game disclosure and this page have been updated together. Previously authority-issued chests keep their sealed reward and are not rerolled when odds change.
