Is video poker rigged? How the machine really decides

On a regulated machine in Nevada or any jurisdiction that uses the standard testing rules: no. The deal has to behave like a real, shuffled 52-card deck, and the casino's edge comes from the pay table printed on the screen. But there are machines that look like video poker and work differently, and the swings of a fair game can feel very unfair.

What the rules require

Nevada. Regulation 14 sets the minimum standards for gaming devices. Under section 14.040, the outcome must come only from chance, the player's skill, or both, and all possible outcomes must be available at the start of each play. For a device that represents a live game, such as poker, the chance of each card must equal its chance in the live game, and any difference must be disclosed to the player. The technical standards add statistical tests for the random number generator, and require cryptographically secure software generators for devices approved from 2027 onwards.

The lab standard. A widely used testing standard is GLI-11 from Gaming Laboratories International (GLI-11 v3.0). For card and poker games it requires that:

• the odds of drawing any card are the same as in the live game;
• cards come from a randomly shuffled deck, and replacement cards are drawn from that same deck;
• removed cards are not returned to the deck, and the deck is not reshuffled during the hand;
• the game does not change or discard outcomes because of how you play, and does not substitute "near misses".

In plain words: when you press Draw, your new cards come off the same deck the first five came from. The machine does not decide your hand is "due" to lose.

Machines where this does not apply

Some machines look like video poker but are not random card games.

• Class II machines in some tribal casinos are legally bingo, with the poker hand shown as entertainment (25 U.S.C. §2703). The result is set by a bingo game in the background, and the cards are drawn to match it. Las Vegas Advisor explains how to spot them: look for a bingo card on the screen. On these machines, strategy may not change the result.
• Central-determination games in two states, New York's video lottery terminals and tribal casinos in Washington state, draw results from a finite, preset pool (Gaming & Media, 2024).

Neither type is "rigged" in the sense of breaking its own rules. But the strategy and returns in our guides apply only to random-deck machines.

So where does the casino win?

In the pay table. With perfect strategy, 9/6 Jacks or Better returns 99.54% of every bet and 6/5 returns 95.00% (exact counts from Wizard of Odds). The deck is fair; the casino sets what each hand pays, and it sets the pays low enough to keep a share over time. See how to read a pay table in ten seconds.

The rest of the edge comes from mistakes. Every hold that is not the best one lowers your return. Some cost a lot: see the 10 most expensive Jacks or Better mistakes.

Why a fair game feels rigged

Because fair is lumpy. With perfect 9/6 play:

• A royal flush comes about once every 40,391 hands: roughly one every 67 hours at 600 hands an hour. Many players go months without one.
• More than half of all hands end with nothing: 54.5%.
• We simulated 200,000 one-hour sessions (600 hands at $1.25) with perfect play on 9/6. The average loss was $3.30, close to the exact $3.42. But the typical session lost $20, because a few big wins (four of a kind, the odd royal) lift the average. Only 36.6% of sessions ended ahead. Over four hours, 30.5% did.

So a losing night on a fair machine is the normal result, not proof of cheating. The machine that "never pays" may simply be the one you remember.

How Perfect Hold deals

Perfect Hold shuffles a full 52-card deck with a cryptographic random number generator before every hand. Your first five cards are the top five; your replacements are the next cards, in order, from the same deck. The tutor sees the same deck when it plays its version of your hand, so you can compare results. It uses play credits only: no money in, no money out.
