Card counting sounds very sophisticated to the general public; however there are some simple ways that can be practiced by normal individuals like you and me. The goal of card counting is to predict whether the players or the dealer have the advantage in the next round of cards. Based on statistical evidence high cards (10s, Js, Qs Ks and aces) put the players at an advantage, while the low cards benefit the dealer more than the players. When high cards are dealt, there will be less high cards remaining in the shoe, making the players less favorable in future rounds. Thus, in these counting systems, negative points are assigned to the high cards. For the same reason positive points are assigned to low cards. This app teaches you 4 popular blackjack card counting techniques - Hi-Lo, Hi-Opt1, Hi-Opt2, and Wong Halves. The purpose of this app is to help you become familiar with these systems so that you can use them when you are at the blackjack table. After playing with the app, you should be able to count cards accurately and quickly with these 4 card counting strategies. Good luck!
