Not enough balance.
Choose a stake and target multiplier, then review the displayed win chance and possible return before playing. Skinstake Upgrader settles in Chips or Shards, according to your selected currency.
Increasing your target lowers the chance of reaching it. Compare the full return with the profit shown in the controls, because the returned amount includes the stake. A higher target does not make a better result more likely.
Upgrader applies a multiplier to your stake. It does not modify items in your Steam inventory. Review your selected currency, chance and potential return before playing.
The homepage shows the current Upgrader King competition and recent upgrade activity. It runs in two hour periods and ranks successful upgrades. The prize pool uses Chips. Check the displayed rules and standings for the current period.
