As mentioned at the outset, when you join Plenty Jackpots Casino, you will receive a 400% welcome bonus OR you can opt for the 100% cash back insurance. Thus, you can join Plenty Jackpots and decide to play with two types of depositing incentives. As a new member, or first time online players, a deposit bonus is given to a player along with their deposit. Deposit bonuses are a match bonus. Whatever amount you deposit, the casino will match the said deposit. Therefore, the higher your deposit, the higher your match bonus will be. If you opt for the 100% cash back insurance instead, it protects you in case the casino wins. Thus, once you have gone through your balance, you can add your real cash back to your account.
