Probability of ruin video poker
5/12/ · Video poker’s risk of ruin formula. Posted on May 12, Filed under: Video poker Online | For games with widely ranging payoffs and probabilities, such as video poker, it has been very difficult to determine bankroll requirements. This phenomenon goes by the evocative name of gambler's ruin. In video poker, gambler's ruin is especially relevant because about 2% of your total payout (it varies from game to game) is due to the royal flush jackpot, which occurs on average once every 40, hands or so. This video poker strategy page and the accompanying section have a single goal—to help you get the best odds when gambling at a casino. Video poker, unlike many casino games, offers you at least some degree of control over the odds.

Once you know R 1 , you can get the risk associated with any bankroll by using . Legend to Table 2: The values in the table give the RoR for various levels of cash back and for various bankrolls. The mean of the distribution added to the previous value every time is positive, but not nearly as large as the standard deviation, so there is a risk of it falling to negative values before taking off indefinitely toward positive infinity. Featured on Meta. And what about the 0. For additional trades, the accumulated risk of ruin slowly increases.
Risk of Ruin for Video Poker and Other High-Variance Games
Risk of ruin is a concept in gambling, insurance, and finance relating to the likelihood of losing all one's investment capital  or extinguishing one's bankroll below the minimum for further play. In a multiple-bet scenario, risk of ruin accumulates with the number of bets: each repeated play increases the risk, and persistent play ultimately yields the stochastic certainty of gambler's ruin.
Two leading strategies for minimising the risk of ruin are diversification and hedging. An investor who pursues diversification will try to own a broad range of assets — they might own a mix of shares , bonds , real estate and liquid assets like cash and gold. The portfolios of bonds and shares might themselves be split over different markets — for example a highly diverse investor might like to own shares on the LSE , the NYSE and various other bourses.
So even if there is a major crash affecting the shares on any one exchange, only a part of the investors holdings should suffer losses. Protecting from risk of ruin by diversification became more challenging after the financial crisis of — — at various periods during the crises, until it was stabilised in mid, there were periods when asset classes correlated in all global regions.
For example, there were times when stocks and bonds  fell at once — normally when stocks fall in value, bonds will rise, and vice versa. Other strategies for minimising risk of ruin include carefully controlling the use of leverage and exposure to assets that have unlimited loss when things go wrong e. For example, with a starting value of 10, at each iteration, a Gaussian random variable having mean 0.
It only takes a minute to sign up. My understanding is that infinitely many scenarios might occur is that correct? However I don't understand the construction of the equations 1. Could anybody explain in simple terms the logic used? Do the equations reflect the infinite scenarios? I am assuming you see how I did this, although if you don't, you can ask me in the comments.

We need a recursion to get the result. If he ties, then the probability to win the match has not changed. Since the events cannot occur simulaneously, the probability that the player wins, is the sum of these probabilities. Similar for the other player. Active Oldest Votes. I am pretty sure your original equations are wrong.
It should be like this: 1. Now, let's look at equation 1. P opponent wins opponent ties for dollar is the scenario where the opponent is in the same place they just were because nothing changed. P opponent wins opponent ties for dollar puts the opponent in the same place they just were because nothing changed. P opponent wins opponent loses dollar is the scenario where the opponent loses because they have zero dollars left.
