Yes, this online slot machine has plenty of bonus features. Every time you land a cluster, the winning symbols are removed and new ones cascade into position. This continues until no new wins are formed. Not only that, but each time a new cascade occurs, the progressive multiplier increases. Furthermore, any chest symbols transform into other symbols or into scatters at the end of the sequence. On top of all that, it has a free spins game with up to 20 free rounds.
