How the Game Plays

Ultra Stack Feature Africa is a safari-inspired video slot from Aruze Gaming that utilizes a larger-than-average 5x4 grid. The game centers on the wildlife of the savannah, featuring high-value symbols such as lions, elephants, rhinos, giraffes, and zebras. Standard card royals from 9 through Ace represent the lower-tier wins. To form a winning combination, symbols must land on adjacent reels starting from the leftmost reel along one of the 50 fixed paylines. The Africa Globe serves as the wild symbol, appearing on the reels to substitute for all standard icons and assist in completing winning sequences.

Free Spins Explained

The core bonus is the Ultra Stack Free Games feature, which is triggered when three or more Diamond scatters appear on the reels. Before the round begins, a selection process or a reveal mechanic determines the number of free spins awarded, with a maximum potential of up to 200 games. During this bonus, the reels are modified to include an increased frequency of the top-paying symbols, significantly raising the likelihood of landing full stacks of the highest-value wildlife icons.

Diamond Action Feature

A unique aspect of the gameplay is the Diamond Action mechanic. When a diamond symbol appears, it can move up or down the grid to reveal a vertical line of consecutive scatter symbols. This movement helps ensure the feature triggers or retriggers more effectively. Additionally, the "Ultra Stack" naming refers to the game's tendency to land long vertical strips of identical symbols, which can cover entire reels to create multiple payline wins simultaneously.
