Frequently Asked Questions
A trade up contract allows you to exchange 10 items of the same quality for 1 item of the next higher quality. The output skin is randomly selected from the collections of the input items, weighted by the number of items from each collection.
You can use any 10 items of the same quality (e.g., all Industrial Grade). The items must be from collections that have skins of the next quality. Souvenir and StatTrak items can also be used but may affect the outcome.
This calculator uses a simplified model assuming equal probability for each skin within a collection. Actual probabilities may vary due to different skin rarities within the same quality.
