Sorry to hear about your luck!
Each item has a percentage chance of being landed on through the Spinner.
The common items, such as Cash, have the highest chance of being landed on, while the rare items have a lower percentage chance of being won.
These percentages are the same for all players. They cannot be manually changed, even if you're not getting the rewards that you're hoping for!
The more you spin, the more chances you have of winning the best items, so we wish you luck with your next spins!
