Dr. Jekyll & Mr. Hyde 2

A Symbol Collector is a powerful special symbol that primarily appears in bonus rounds like 'Hold and Respin'. Its sole function is to 'collect' the values of other cash value symbols (like coins) on the screen and absorb them into its own value. It goes beyond simply adding values, playing the role of consolidating scattered small values into one massive value to exponentially amplify the potential of the bonus round.

A Shapeshifter Symbol is a highly unpredictable and powerful feature where, during a bonus round, a symbol randomly 'transforms' into a different type of special feature symbol (e.g., Collector, Payer) on every spin. The core of this feature is that it doesn't have one fixed ability but changes its ability each time, turning every moment of the bonus round into a completely new situation. This provides players with maximum tension and replay value.
