Many of Fazi’s core slots use familiar structures such as fixed paylines, Wilds, Scatters, free spins and straightforward paytables. Wild Hot 40, for example, uses a 5×4 layout with 40 fixed paylines plus Wild and Scatter symbols. This makes part of the catalogue suitable for players who prefer a classic format without heavily layered bonus systems.
At the same time, Fazi develops several recurring feature families. Booster editions exist across Golden Crown, Very Hot, Epic Crown, Wild Hot and other ranges. Extreme is also used for modified versions of popular fruit-slot series. Elsewhere in the catalogue are games with free spins, expanded line counts, special symbols and Dice variants.
A more modern example is Wild Hot 40 Hold & Win. When the relevant feature is active, the Hold & Win bonus triggers with five or more Coin symbols. During the feature, players fill positions with coins; filling all 20 positions awards the Grand Jackpot. Mini and Major levels are also present, giving the game a substantially different feature set from the original Wild Hot 40.
No single mechanic defines the entire Fazi catalogue. Instead, the provider gradually adds newer features to recognisable classic series, so very simple fruit slots can sit alongside more feature-heavy Hold & Win or Extreme versions.
