I did the analysis for AGS back in 2017 when they developed the game, and I’ve previously posted all the details about the house edge and the original bonus. The players and dealer then each receive three hole cards, which is more interesting than UTH’s two hole cards, because of the increased ways to make a hand.
Structurally, it’s similar, where the player paces equal Ante and X-Tra wagers (similar to UTH’s Ante = Blind) before the hand begins. It’s fun and relaxing to just play symbols and colors, and there’s a lot more different outcomes than in simple Ultimate Texas Hold’Em. AGS’s Hold’Em-style flush game has recently arrived at my local Viejas Casino, and now it’s all I play anymore.
