# Royal or Bust

## Introduction

The purpose of this page is to answer such questions as, "If I have a bankroll of \$2,000, what is my probability of hitting a royal flush before going broke?" The information in this page will not increase the player's odds, but it may be of use to the player in planning a budget if his goal is to hit a royal or go bust trying.

In addition to a "royal or bust" table, we will also look at the bankroll needed to hit four deuces or better in two deuces wild games. We also have a table for the probability of ruin by bankroll size if the goal is to hit a win of 25 or more, which is a four of a kind or better in non-wild card games and a wild royal or better in deuces wild games.

In all tables, the bankroll is measured in full bets. For example, a bankroll of 100 at a \$1 game would be \$500, because the player should be betting five coins, or in this case \$5, at a time.

Following is a list of games covered by this analysis.

## Royal or Bust

It seems to me that recreational gamblers often have a weekend goal of hitting a royal, at which time they immediately quit playing. The following table strives to answer the question of the probability of success for various bankroll sizes and common games.

For example, consider a player has a bankroll of \$2,000 and is playing a 9-6 Jacks or Better on a 25¢ game. A full bet, which video poker players should always make, is five quarters, or \$1.25. That comes to a bankroll of \$2,000/\$1.25 = 1,600 bets. The table shows the player will have a 78.03% chance of hitting a royal before going bust.

## Win of 25 or More or Bust

The following table shows the probability of a win of 25 or more for various bankroll sizes. I chose 25 because it the usual minimum pay for a four of a kind in games without wild cards. It is also a common win for a wild royal in deuces wild games.

For example, suppose a 9-6 Jacks or Better player puts a \$100 bill into a 25¢ machine. What is the probability he will see a win of 25 bet units or more before going bust? \$100 will buy 100/1.25 = 80 full bets on that machine. The table shows the probability of seeing a four of a kind win or more before the \$100 is gone is 83.86%.
