TF2 Upgrader — Upgrade Your Team Fortress 2 Items

What the upgrader does

The upgrader turns something you already have into a chance at something you want. Load items from your inventory — or switch to coins-only and stake balance instead — then pick any item on the marketplace as your target. The site works out your win chance from the value gap between the two sides: a small step up gives a high chance, a jump to something far more expensive gives a small one.

Win and the target item is yours, delivered to your site inventory ready to withdraw. Lose and the items you staked are gone. There is no partial outcome.

Low and High

Before spinning you choose whether Low or High wins. Low wins on a ticket at or below your chance; High wins on a ticket at or above the opposite end of the range. The two are mirror images — the size of the winning band is identical either way, so your odds do not change. Only the numbers that count as a win change. It exists because people have strong preferences about which end of a wheel they want to land on, not because one is better.

Chance limits

The highest chance you can set is 85%. There is no fixed floor: the lowest chance available depends on how far your target sits above your stake, so a very cheap stake aimed at a very expensive unusual will produce a correspondingly small number. The exact percentage is shown before you commit, and it is the number the round is actually settled against.

Verifying an upgrade

Each spin's ticket is drawn before the wheel moves, and the record is available from the round afterwards. Fast mode shortens the animation only — the outcome is already decided when you press the button, so skipping the spin cannot change it.
