Generally, a player has to make some action during the bonus game, such as selecting a particular object, or collecting points in order to win a reward, or matching symbols. Sometimes more imaginative and exciting games are offered.

A free spins feature is one of the most interesting features. It is not only a much attractive part of a slots game; the free spins feature has made the game itself even more famous. With this feature, it is easier for a player to get to spin the reels for free, when certain symbols appear.

More free spins can be activated while the player is spinning for free.
