As we can see, the probability of a house win fluctuates around 0.52 and 0.518 and averages at 0.5188. The picture hosted here in GitHub shows the variation in the house edge every 1 million hands. You can surrender after you get your hand if the dealer's card isn't an ace.Īfter simulating a total of 20 million hands the results were registered in an open document spreadsheet.21's obtained in splitted aces are considered 21, not blackjacks.Split aces only get one card each, you are not allowed to hit.You can only split once (two hands maximum).This casino also uses CSMs (Continuos Shuffle Machines) which makes card counting between each round useless, since all the cards are put back in the deck and are in theory shuffled, resetting the counts. These variations have a big influence in the odds of the player. Teste.java - Creates a Blackjack object and runs the simulation ('main' method).Įach casino has his own rules of the game.Their purpose is to add more randomness to the game and allow the 'Myself' object to have more cards to count. Each player draws until they reach a desired score or bust (much like a dealer). These player's game choices are fairly simple. Player.java - Represents another player at the table.It saves the number of bets made, the number of won bets and the number of lost bets. This class represents the player and includes all the important decision-making algorithms. Myself.java - One of the most important objects.Includes the Durstenfeld Shuffle algorithm (Fisher-Yattes optimized) to guarantee a realistic shuffle. It can be initialized with more than one deck (normal in nowadays' casinos). Deck.java - The 'shoe' used in the game.Dealer.java - Represents the Dealer of the game and his cards.It represents a Blackjack game following all the game's steps. Blackjack.java - This is the object that sticks all the other ones together.Almost all represent an important object. Here's a small description of each class in the source code. Thorps basic strategy, described in his book Beat the Dealer. The objetive of this simulation is evaluate whether it's possible to play Blackjack in Lisbon's Casino and win money consistently following Edward O.

The following code allows anyone to run a desired number of iterations on a virtual Blackjack game. This project was developed with statistical purposes.
