In game «Videos Poker» exist the rigid and simplified rules concerning size bankroll (Bankroll) which sum would allow to play professionally. Under bankroll understand quantity of money on game to the account of the player which it can use for game conducting. Similar rules and principles exist not only for Poker Video, but also for other games, for example, for BlackJack in which the player can get on long intervals of game advantage before a gambling institution. Better to say, it is necessary to possess big enough bankroll to avoid risk of loss on rather short time interval. The rigid principle of size bankroll On the basis of calculations of mathematicians which have calculated the necessary sum for game in Video Poker professionally, has been deduced a principle «3 to 5». This principle is complicated, as in mathematical model variability and aversion of risk of loss is considered. Aversion of risk – unwillingness to incur risk in case of absence of any indemnification. That it is safe to play Video Poker, it is necessary to have bankroll in 3-5 times more than the prize sum at loss of combination Royal Flush (Flash Royal). For descriptive reasons, we will consider a concrete example: to play the game car in Video Poker with rates of 25 cents, it is necessary to have on game to the account from 3000$ to 5000$. If game goes by the car with the rate of 1$ bankroll should make already 60 000$ – 100 000$. Besides it is necessary to have more money for games with changeable in percent of payments and less money – for Video of Pokers from 101 % of payments.The simplified rules of size bankroll More democratic and accessible rules still name optimum. Them so named, because they mean game conducting more after careful consideration, with use of various strategy. For simplicity of perception, we will consider probability of loss of combination Royal Flush (Flash Royal) if the player has only 100$. Such analysis we will spend in two games of Video Poker – «Jacks and Ten Is more senior» and «and Is more senior». At first we will consider slot machines «Jacks and Is more senior» with the maximum rate 1,25$. We will divide available 100$ into the sum of the maximum rate 1,25$ and we will receive quantity of rates – 80 which it is possible to play. If to consider that “Royal Flesh” drops out about time in 10 000 played rates the probability of reception JackPot will make 1 to 500. However such Togel Singapore method does not consider the sum which you can win, in the course of game. The percent of payments on game «Jacks or Better» is on the average equal 88,8 %. That is from put 100$, the player will receive 88,8$ in the form of a prize. On this money it is possible to make 71 more rate. Certainly, after 71 rounds, the player receives back 78,75$ from 88,8$. On them it is possible to play 63 rounds. And so on. To learn how many the player will play games with the prize account, we will take advantage of the formula: 80 rates we will divide into a difference 1 and 0,8888. Thus we will receive 80 / (1-0,8888) = 715 games. But from the moment of loss to “Penalty” (Four of a Kind) – JackPot will drop out on the average each 424 games. We will add it to percent of payments and we will receive 94,75 %. If we will count how many games it is possible to play, we will receive 80 / (1-0,9475 =1520 rates. A conclusion: 1520 games give to the player probability of loss «Royal Flush» 1 to 26. The sum of money of 26 times больший than 100$ – 2600$ is necessary to have an opportunity to win JackPot. In game «Tens also Are more senior» (Tens or Better) the percent of payments is made by 97 % that is more than 94,75 % in game «Jacks or Better». Such advantage gives the chance to play more games at identical quantity of money on the account. We will calculate their quantity – 80 / (1-0,97 =2665. The quantity of rates in 1,25$ can be made much more. And probability of loss of a combination of “Royal Flash” has increased to 1 to 15. I.e. to the player for stable game before reception JackPot, it is necessary to have 1500$ on game to the account. Summing up, it is possible to tell what to win JackPot much easier in game «Tens and Is more senior» (Tens or Better), than in game «the Jack and Is more senior» (Jacks or Better). But it and is logical, because rules of games differ. Irrespective of a kind of a slot machine for game in Video Poker, the player will always receive a portion of adrenaline. To learn to play Video Poker it is possible on emulators game «Video Poker» in any the Internet of a casino online. Now, to count up the sum of money for confident game in Video Poker any can, irrespective of its version.
