However, the statistics on the right will still reflect your first answer, so you can see how you're doing without the trainer's help. In WARN mode, the trainer will only come on if you make a mistake, showing you the better play and giving you a chance to change your answer. You won't learn as much if you leave the trainer on all the time and just copy its answers, so we recommend playing with the trainer in WARN mode. The statistics on the right show your playing time, speed of play, the theoretical payback percentage of the game with perfect play, the projected payback percentage with your plays, and the cost of errors. Yellow dots on the corners of the cards show the best cards to hold. The CHANGE CARDS button allows you to explore the best play returns for hands that you enter. When the trainer is turned on, it lists the best plays and their average expected wins on the left. You can use the mouse to click on cards to hold, or you may find it easier to use the keyboard: Select from 19 different video poker variations with the button, including Jacks or Better, Bonus, Double Double, Triple Double, Full Pay Deuces, 16/10 (Not So Ugly) Deuces, Loose Deuces, three kinds of Joker Poker, and more.
