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™'.
Special Reel Set is a feature where a bonus round, such as free spins, is played not on the same reel configuration as the base game, but on a separate reel set specially designed just for the bonus. The core of this feature is to fundamentally increase the value and anticipation of the bonus round by using a special reel set with a richer symbol configuration (e.g., removal of low-value symbols, addition of high-value symbols).
