Some roles are more represented than others, but the feature mix extends beyond a clear one- or two-role focus. The wild family brings combination-forming mechanics into the mix. Special-purpose symbols provide a route to separate prizes.
A compact feature set keeps the mechanical picture focused, with only a few special mechanics to follow alongside the core format.

Each bar counts the features that contribute to a functional role. One feature can contribute to more than one role. Bar lengths are scaled to the largest count within this game; compare the numbers when looking across games.

Expanding Wild is a powerful and visual feature where a wild symbol, upon landing in a single position on a reel, expands vertically with a special animation to cover that entire reel. The core of this feature lies in the 'instant transformation' where a single symbol's appearance turns the entire reel into a 'Wild Reel'. Its goal is to complete multiple winning paylines at once.
An Instant Prize Symbol is a special symbol whose role is to pay a set cash value or bet multiplier just by appearing on the reels. The core concept is that it provides a direct reward by its mere presence, without the need to form a winning line like regular symbols. It is often called a 'Coin' or 'Money Symbol' and serves as the most basic 'material' in various bonus features of modern slots.
