Money Symbols – Money symbols can be valued anywhere from 0.5x to 50x the stake. These values are collected if wilds land simultaneously. Every wild symbol in view collects a value for each money symbol.

Free Spins Feature – A maximum of 6 free spins will be awarded if you land six to eleven money symbols, whereas eight free spins will be awarded if you land 12 to 17. Symbols 18 to 20 can trigger 10 free spins. The bonus round progressive feature starts at the value of the symbols collected before you begin. Whenever a money symbol appears on the grid, it adds to the collected value, and if a wild appears, it awards the current collected value. You get +2 free spins for each six money symbols.

Final Thoughts

The main attraction of this game would seem to be the free spins feature, but with the money symbols, it’s quite different from the standard free spins. Players have the potential to win up to 4,500x the stake.
