Highlight Features

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™'.

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.

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.
