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).
Low Bonus Buy Price
This slot's bonus buy price is below the usual range for comparable slots. That makes buying the feature relatively accessible, especially if you want to try the free-spin round directly. Keep in mind that some games offer multiple free-spin tiers, and SlotWise uses the lowest available buy price as the reference. A lower price may also mean that the free-spin feature itself carries a lighter payout profile than higher-priced games.
Each SlotWise Preview examines a game’s rules, specifications, and special features. We identify individual mechanics and map them to standardized feature categories, then use FeatureMatch™ to describe the game’s mechanical character. Alongside free demo access, this gives you a consistent starting point for understanding and comparing games. Where a 300SPINS™ review is available, it adds observations and results from a recorded play session.
