A Virtual Deck Has to Behave Like a Deck
Video poker turns a familiar card draw into software: the machine deals a hand, lets the player choose which cards to hold, then replaces the rest. In regulated versions, the software must produce card outcomes with the probabilities expected from an unrigged deck—not quietly favor certain cards or hands.
That means the cards are not independent draws. Once a card appears in a hand, it is no longer available for the replacements, just as in a physical deck. The software uses a random-number generator to select outcomes, but the important test is whether those outcomes follow the right distribution: over many plays, each possible hand should occur at the rate the game’s rules imply.
Fair Cards, Different Payouts
The payout schedule is the table of awards for hands such as a pair, a flush, or a royal flush. It does not change how likely those hands are under a fair deal. It changes what the machine pays when they occur—and therefore changes the game’s expected return.
Players also influence their chances of winning by choosing which cards to hold. The same initial hand can lead to different results depending on that decision, but the software’s card probabilities remain the same. A favorable strategy cannot make a rare hand common; it can only make better use of the chances the rules provide.
Why the Distinction Matters
The requirement separates two questions: Are the cards dealt fairly, and how generous are the awards? A game can use honest card probabilities while offering a less generous payout schedule than another version. That is why the paytable matters even when two machines look alike—and why a displayed prize alone cannot tell a player how often it is likely to arrive.
