Picture; Daily Gem Bonus Spinner.
The Gem Bonus, also known as the Daily Spin, is a feature that appears daily where members can earn Gems and Diamonds. If a user logs in two days in a row, their price will be multiplied by two, and if a user logs in three days in a row, their price will be multiplied by three. Unfortunately, the maximum bonus it "x3", meaning that if you log in four days in a row, your price won't be multiplied at all.
