You can choose items you would like to upgrade or directly use money from your balance. Those items or money will be traded to get XP and a chance to obtain a better desired item.

You have to select an item that you would like a chance to win. You can either select it from all the available items or target a multiplier. The multiplier will choose an item close to the value of the items to trade multiplied by the desired multiplier.

You have control over the result! You choose the range within which you will either win or lose. The result will be the same no matter what you choose, so it's up to you!

Once you have everything set up, you can start the upgrade process. What matters in determining whether you win or not is the inner full circle and the needle. If the needle ends up pointing to a filled section of the circle, you win! Otherwise, you lose.

Once the upgrade is done, you immediately earn XP depending on the item you traded. If you win, the item goes directly into your cart. You can sell it, re-upgrade it, or just withdraw it!
