Aruze Gaming does not use one universal mechanic across all of its games. Instead, the provider develops several recognisable families with different feature structures.
Ultra Stack. Bonus rounds in these slots often increase the presence of a selected high-value symbol. Ultra Stack Egypt, for example, uses a special reel set during free games and determines a win multiplier through a mini-game. In Ultra Stack Poseidon, the bonus starts with a choice between several free-game options.
Cannonball. This family is built around special Cannonball symbols. In Cannonball Rhino, Lion, Wolf and related versions, they are tied to free spins, multipliers and jackpot features. Some titles in the series advertise multipliers of up to x30, while the number of special symbols can increase during free games.
Burning Hot Jackpot. These games combine a stepper format with a bonus round and multiple progressive jackpot levels. Official descriptions for Howling Wolf, The Great Inca and Aztec Sol show the themed bonus leading into a Jackpot Challenge.
Choice features and mini-games. Aruze often inserts a short interactive step between the base game and a bonus, such as choosing an object, spinning a separate wheel or selecting the parameters of free spins. This gives parts of the catalogue a more interactive feel than traditional slots with no secondary screens.
