How to compare a case against a platform
- 1Note the rarity tier for each item rather than the item name alone; tiers carry the odds.
- 2Check whether the case still drops, since a discontinued case trades at a different price than its listed pool suggests.
- 3Compare the published tier odds here against the operator version of the same case.
- 4Use the fairness checker before treating any listed value as a return.
