Heartburst Slot Bonus Features

Free Games Feature

If you land 3 or more Lucky 7 symbols in the main game, the Free Games feature will be triggered. The good news is that the Free Games feature itself can also be retriggered again while in the Free Games round, meaning your Free Spins amount would be replenished! The number of Free Games you receive will be dependent on how many Lucky 7 symbols you are able to find at any one time. The number of Free Games awarded are as follows:

3 Symbols - 15 Free Games 4 Symbols - 20 Free Games 5 Symbols - 25 Free Games

Substitute Symbol

The Heart symbols are also well worth looking out for in the Heartburst slot game, as they can substitute for any other symbols on the reels other than the Lucky 7. These Heart symbols can only show up on reels 1, 3 or 5. If found, the Heart symbols will expand and fill the relevant reel before any wins are awarded. If a Heart symbol substitutes for another symbol in a winning line in the Heartburst slot game, prizes will be tripled.
