Spartan Slots 15% Cashback Bonus 

A cashback bonus is an amount that you get in your account after you have incurred losses. The bonus amount is calculated as a fixed percentage of losses or deposits. Spartan Slots casino knows how to cheer up its members; therefore, it offers a 15% cashback bonus every Monday.  For instance, if you had made two deposits in the preceding week, you will get 15% of the total amount deposited, which will be credited to your account on the following Monday.

Please note, if you have made any withdrawals during the previous week's period, the bonus is no longer valid.
