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'.
Average Bonus Buy Price
This slot's bonus buy price sits within the usual range for comparable slots. Buying the feature can be a reasonable option if your goal is to reach the free-spin round without waiting for a natural trigger. The trade-off is that you skip the base-game spins that would normally happen before the feature, including any wins or volatility from that part of play.
