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 Positional Multiplier is a unique and strategic system where the multiplier applied to winnings is not applied globally to the whole game, but is instead tied to and grows in a specific 'position' or 'spot' on the reel grid. The core of this feature is that the game remembers the positions where wins occurred, and then creates and grows multipliers if another win happens in the same spot. This provides a new kind of fun for the player, as if they are 'building a base' and 'cultivating the land'.
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.
