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 Multi-Function Symbol is a highly efficient and powerful hybrid symbol where a single symbol simultaneously performs the roles of two or more core special features, such as Wild, Scatter, Mystery Symbol, etc. The core of this feature is to elevate the game's complexity and potential by creating the expectation that the appearance of a single symbol can bring multiple positive outcomes at once.
