Most slot games have a pay table area that displays information on the jackpot amounts for specific reel combinations. These are sometimes displayed prominently on the machine, and in other cases — typically on video slot machines — they are available through an interactive series of images that can be switched between to view all possible win combinations. This feature can help players make informed decisions about what they want to play and the best strategies for doing so.
