Ultra Stack Diamond™ is the newest jewel to the Ultra Stack™ titles. A clone of Aruze’s top performing game Ultra Stack Lion™, this 5 reel 50 line video slot machine has a recommended denomination of 1¢ and a minimum of 50 credits to play. This G-SERIES™ machine is equipped with the JEWEL FEATURE which is triggered when 3 scattered FEATURE symbols appear on reels 2, 3, and 4 awarding a MINI GAME and 8 FREE Games. The MINI GAME consists of a 5 JEWEL CASE selection in which each case contains a different jewel symbol. The revealed jewel symbol in the MINI GAME will advertise its’ beauty on the reels more frequently during the 8 FREE GAMES as it increases the possibility of a full stack of jewel symbols. These jewels are highlighted in numbers as they appear side-by-side and in groups for players to adore as they anticipate big wins. This feature is retrigger-able within the feature awarding an additional 8 FREE GAMES. With this ULTRA STACK™ machine every reel spin could stack up bright with diamonds.
