Once a game type, number of lines of play and pay table are selected, there are three different modes of usage: Perfect Hold Advice - select five cards from a deck and a sum of the current multipliers and this app shows a perfect hold hand, that is, the cards to hold that maximizes the average or expected long-run payouts. (Some hands have more than one optimal play and you set the criteria to break the ties. These hands are indicated.) Scored Practice - here a random hand and current sum of multipliers is dealt, the user selects hold cards and then this is rated against a perfect hold hand. The current sum is randomly generated according to the theoretical frequencies of seeing them. You may over-ride the generated sum and select your own. Game Mode - a player just plays the game for fun where random cards are dealt, the player selects hold cards, a draw is made and any payouts recorded. The same draws are used to fill-in a perfect hold hand for comparisons so one can learn perfect play as they go. Trip Recorder - this feature is used to record data associated with video poker gambling trips or activity. Each hand, regardless of mode, is saved for later review. Each Perfect Play is explained in detail if desired. This is a powerful aid if one is vulturing. Extensive help screens are provided as are information buttons throughout the screens. NOTE: Our Apps teach you how to play Perfect Video poker through simulated play with feedback on errors. No prizes or money are involved. In short, no opportunity exists to win real money or prizes based on the outcome of a simulated game in our Apps. The Ultimate X and Bonus Streak Ultimate X games supported are for One, Three, Five and Ten Line games.
