Frequently Asked Questions
- How does the CS2 trade-up builder work?
- Add up to 10 input skins of the same rarity, and the builder calculates every possible outcome in real time. It shows the probability, expected float, and market price for each result so you can evaluate the contract before committing.
- Can I choose a specific trade-up outcome?
- You can pin a desired outcome to see which input combinations maximize its probability. The builder recalculates odds and expected profit as you add or swap skins, helping you optimize for the result you want.
- What is the difference between the builder and the scanner?
- The scanner automatically finds profitable contracts from current market data. The builder lets you craft your own contract from scratch — choose specific skins, adjust float values, and explore what-if scenarios to plan a trade-up that fits your inventory and budget.
