Ultra Stack Feature

This new game in Aruze’s G-Series group of core video slots includes a base game featuring the slot-maker’s popular “Ultra Stack” feature, which randomly stacks groups of symbols—including wilds—for big wins. But this game includes that feature in a novel type of free-spin round.

It’s novel because the game can randomly award up to a total of 200 free spins. When three “Feature” symbols trigger the Ultra Stack Free Games event, the number of games starts out as calculated by the triggering symbols. Each Feature symbol contains a number from one to 10, with the total translating into the number of free spins.

Then, a random number of pandas can jump onto the reels, each increasing the number of free games. If 50 pandas jump onto the game screen, the number of free games rises to 200.

The game gives the player the option of taking a straight credit award, rather than sitting through 200 spins.

The feature happens with very high frequency—according to the manufacturer, one in every 10 spins triggers a free-spin event. Combined with the 50-line configuration, this results in a lot of time-on-device for the player in what Aruze officials say should be one of the company’s most popular titles in the coming year.
