3 BestCS2 Upgrader Sites

Upgraders let you stake one skin for a chance at a pricier one, with the win probability set by the value gap. The two things worth checking are whether the probability shown matches a provably-fair roll, and how the site prices both skins — pricing is where quiet edge hides. Every site below had both checked by us before listing.

Frequently asked

Are upgraders rigged?
On provably-fair sites the roll itself is verifiable. What you should scrutinise is pricing: if the site values your skin low and the target high, the displayed odds can be honest while the trade is still poor value.
What success chance should I take on an upgrade?
There is no free lunch — every displayed percentage already includes the house margin. Smaller multipliers mean smaller variance, not better expected value.
