Summer Event: Why didn't I get the prize I wanted from the wheel of fortune?

The Wheel of Fortune has different kinds of prizes available, and some are easier to get than others. Won rewards will be removed from the wheel, but some prizes can be won multiple times, though.

The fewer the prizes on the wheel, the higher the chances to get the desired reward. The green prizes have the highest chance to be won (since they're most present on the wheel), the golden prizes are the hardest ones to get, as they only exist once. Refreshing the Wheel of Fortune will also refill it with different rewards.
