Mr Cashback himself is the wild symbol and he can substitute for all the other symbols, except the scatter symbol, to help and form winning combinations.
The scatter symbol is the game's logo; it offers scatter payouts of up to 100x the total bet for a spin and it triggers the free spins.
If you have been spinning the reels and no active payline produces a win for 50 spins then the Mr Cashback feature it triggered and you win back 50x your line bet. Furthermore, the status is saved so if you leave the game and then come back later it will pick up where you left off.
If you land three or more scatter symbols anywhere on the reels the Free Spins begin. You are given 12 free spins during which all payouts receive a x2 multiplier. Furthermore, after each spin at least one wild is added to the reels and will remain in place for up to four spins. Thanks to this it is possible for numerous wilds to be on the reels at any one time.
The slot also offers a gamble feature that can be used after any winning spin to try to double your money. Simply guess if the next card drawn from a pack is red or black. If you guess correctly then you can keep going up to the double up limit.
Mr Cashback has a huge top payout of 7,500x for landing five wild symbols along a payline. The bags of coins can payout up to 800x, the stacks of money can payout up to 500x and the piggybank can payout up to 300x.
