Two roles are especially well represented here: separate prizes and persistence and growth. Special-purpose symbols provide a route to separate prizes. Spin-related mechanics include a state that persists or develops as play proceeds.
An extensive feature set brings together a wide range of special mechanics, giving the game more individual systems to explore alongside its core format.

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 Multi-Function Symbol is a highly efficient and powerful hybrid symbol where a single symbol simultaneously performs the roles of two or more core special features, such as Wild, Scatter, Mystery Symbol, etc. The core of this feature is to elevate the game's complexity and potential by creating the expectation that the appearance of a single symbol can bring multiple positive outcomes at once.
Each SlotWise Preview examines a game’s rules, specifications, and special features.

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.
