Special Features
Feature Highlight: Hold and Respin
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™'.
Feature Highlight: Multiplier Symbol
A Multiplier Symbol is a special symbol that doesn't form winning combinations on its own, but provides a random multiplier value just by appearing on the reels. The core of this feature is its role as a 'seasoning' that amplifies an ordinary win into a massive prize worth tens or hundreds of times more when it appears alongside a regular win.
