Instead of a massive bluff or a heartbreaking bad beat, a very rare WSOP dealer mistake just kicked off the 2026 WSOP (taking place from May 26 to July 15), with a truly bizarre and amusing incident. The hand in question occurred during the first of the 100 events on offer in this year’s series, and we are pretty confident this is something even the most seasoned poker players will be talking about for a long time.

Professional poker player Mike Holtz shared a viral Twitter post that quickly caught the attention of the entire gambling community. Right in the middle of a hand of the 1st event, an instruction card appeared on the flop!

Let us break down exactly how this happened.

The Story Behind the Viral WSOP Dealer Mistake

This bizarre incident happened at the first tournament of this summer’s WSOP. Players were seated for Event #1: the $550 Mini Mystery Millions, which always draws a massive crowd. Tension was high as the dealer dealt the flop, but everyone at the table suddenly froze.

Between the K♥ and J♣, the third community card was a printed instruction card. Mike Holtz was sitting right there and captured the entire room as they laughed in shock. When an unexpected anomaly like this happens, the game stops, and the tournament director (the floor) is called immediately.

Why the Rules Required a Foul Deck Misdeal

According to the strict rules of poker, the situation was very clear. Because a foreign 53rd card entered the game, the deck was officially considered a “foul deck”. Therefore, the floor immediately declared a misdeal.

In this situation, there is no room for debate or negotiation. Players instantly get their bets back, the hand is canceled, and the dealer must grab a fresh deck. Arriving at the table, the floor perfectly captured the humor of the moment.

“We got a pretty good flop, look. It is an instruction card teaching us how to play.”

How Did an Extra Card Survive the Shuffle?

You might wonder how a professional dealer could leave an extra card in the deck. Casinos have strict protocols for introducing a new deck of cards to a tournament table. Typically, the dealer must follow these three essential steps:

The Spread: The dealer spreads all 52 cards face up on the felt to ensure no cards are missing.
The Removal: They carefully remove the jokers and any promotional or instruction card included by the factory.
The Wash: The cards are turned face down and thoroughly scrambled before the first official shuffle.

In this case, a simple human error led to the WSOP dealer mistake. The extra card is likely stuck to the back of a standard playing card during the visual spread. With thousands of players swarming the room on opening day, fatigue can easily cause these tiny slip-ups.

Boxed Cards vs. Illegal Decks

The poker community had a field day with the hilarious Twitter post Holtz shared. One player joked that they were holding pocket “Hand Rankings” and were furious because they flopped a set but lost the pot! Others debated the specific rules governing this misdeal.

Many fans wondered what made this different from a standard “boxed card”. A boxed card is simply a normal playing card that accidentally ends up face-up in the deck. When a boxed card appears, it is treated as worthless paper, and the dealer simply deals the next card.

However, because this was a completely foreign 53rd card, a misdeal was absolutely mandatory. You simply cannot continue a hand of Texas Hold’em with an illegal deck.

The Impact on New Dealer Ratings

Although the World Series of Poker is the most professional poker event in the world with the longest history, such small blunders remind us that the cards are still dealt by flesh-and-blood people. Who, moreover, can be rated due to a new feature introduced this year. It is questionable what rating the dealer will receive after this, but it is certain that this hand will go down as one of the most memorable and funniest moments of the 2026 WSOP.
