Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.
A Global Multiplier is a powerful system, primarily used in bonus rounds like free spins, which refers to a single, unified multiplier that is applied to all winnings that occur during that round. The core of this feature is that it is not tied to a specific symbol like a 'Multiplier Wild' or to a specific position like a 'Positional Multiplier', but acts as a 'Global' rule that governs the entire round, fundamentally amplifying the value of every win.
