Video poker differs fundamentally from slot machines because player decisions directly impact the outcome. The pay table is the single most important factor determining long-term returns. A pay table specifies the payout for each winning hand combination, and even minor variations significantly affect the theoretical return to player percentage.
The return percentage, also known as RTP (Return to Player), represents the average amount returned to players over an extended period of play. For example, a machine with a 99.5% RTP returns an average of $99.50 for every $100 wagered, though this only materializes over thousands of hands. The remaining 0.5% represents the house edge.
Understanding pay table variations is crucial. Two machines may appear identical but offer different payouts for flushes, straights, or full houses. A full house paying 9-for-1 versus 8-for-1 creates a measurable difference in overall return percentage. Professional players compare pay tables across casinos to locate the most favorable options, sometimes traveling between establishments to maximize expected value.
The denomination also matters significantly. Higher denomination machines (quarters versus pennies) often feature superior pay tables with better return percentages. This counterintuitive reality stems from the economies of scale in casino operations.
