The easiest way to solve for x in such cases, in my opinion, is experimenting with different values, using the higher and lower techniques like the Clock Game on the "Price is Right" , until the f' x gets very close to zero.
For " Full Pay Deuces Wild ," with a return of I have heard a rule of thumb that to make it in video poker you should have a bankroll of 3 to 5 times the royal amount you play for.
If playing Full Pay Deuces wild, the exact amount is 3. Here is how many bets were required on average to double the bankroll at various bet sizes.
If a winning wager would put the bettor over double the bankroll, he would only bet what was needed to exactly double the bankroll.
In my Sep. My reasons are explained there. German translation of this page. Read my review. Casino Gambling for the Winner. The Kelly criterion is otherwise called Kelly bet, Kelly formula, and the Kelly strategy.
When this strategy is used in betting, it is calculated as;. The tendency of the trade or bet to give a positive return is represented by W.
This gives:. For a rigorous and general proof, see Kelly's original paper  or some of the other references listed below. Some corrections have been published.
The resulting wealth will be:. After the same series of wins and losses as the Kelly bettor, they will have:.
This illustrates that Kelly has both a deterministic and a stochastic component. If one knows K and N and wishes to pick a constant fraction of wealth to bet each time otherwise one could cheat and, for example, bet zero after the K th win knowing that the rest of the bets will lose , one will end up with the most money if one bets:.
The heuristic proof for the general case proceeds as follows. Edward O. Thorp provided a more detailed discussion of this formula for the general case.
In practice, this is a matter of playing the same game over and over, where the probability of winning and the payoff odds are always the same.
In a article, Daniel Bernoulli suggested that, when one has a choice of bets or investments, one should choose that with the highest geometric mean of outcomes.
This is mathematically equivalent to the Kelly criterion, although the motivation is entirely different Bernoulli wanted to resolve the St.

Key Takeaways Although used for investing and other applications, the Kelly Criterion formula was originally presented as a system for gambling on horse races.
The formula is used to determine the optimal amount of money to put into a single trade or bet. Some argue that an individual investor's constraints can affect the formula's usefulness.
These two factors are then put into Kelly's equation which is:. Gamblers can use the Kelly criterion to help optimize the size of their bets.
Investors can use it to determine how much of their portfolio should be allocated to each investment. Investors can put Kelly's system to use by following these simple steps:.
The percentage a number less than one that the equation produces represents the size of the positions you should be taking.
For example, if the Kelly percentage is 0. This system, in essence, lets you know how much you should diversify. The system does require some common sense, however.
Allocating any more than this carries far more investment risk than most people should be taking. This system is based on pure mathematics.
