How skin upgraders work
You pick a skin (or balance) to risk and a target skin worth more. The site shows your chance, roughly the ratio of the two values minus the house edge. Win and you get the target skin; lose and your stake is gone. Lower multipliers mean better odds.
FAQ
- Is upgrading skins worth it?
- Only as entertainment. On average you lose the house edge on every upgrade, and higher multipliers have lower odds.
- Are upgrade odds fair?
- On provably fair sites the roll is verifiable. Check that the chance shown matches the value ratio: a big gap means a high house edge.
