  • Bonus Features: The Hyperspins, or reel locking, is the main feature in this game. If you go to the settings, there is an option to have the game recommend good times to hold reels, based on your preferences. The value of each reel will depend on several factors, including the symbols on the reel and whether other reels are also locked. So, for example, a reel with a scatter on it will cost more than a reel with a 10, and if you hold 2 reels, each with a scatter symbol, the second one will cost even more.

    When you get between 3 and 5 scatter symbols on the reels on a single spin, you will activate the bonus spin feature. Before the extra spins begin, one symbol will be chosen at random to be an expanding symbol. That symbol will expand in during spins when a win can be completed. Once the symbol is chosen, you will have the option to have another symbol selected in hopes of getting a better symbol. Of course, you also run the risk of having a lower value symbol selected.
