Blackjack or Twenty One is a common casino card game whose goal is to get your hand’s value as close as possible to 21 without exceeding it. This implementation of the game allows you to surrender you hand and lose half your original bet provided that the dealer doesn’t have a natural blackjack. Doubling your original bet is also allowed. The option to buy insurance if the dealer’s up card is an ace is also available. When insurance is used you must bet half of your original bet. You may also split a pair into two hands however re-splitting is not allowed. Insurance, splitting or doubling is not allowed if you don’t have enough cash to cover the new bet. You may add more cash to your total before a round starts by selecting the “add more cash” button from the menu. This game is for entertainment purposes only and does not use any form of real money. This game can be played with 1 or 6 decks. When you play with 1 deck, blackjack pays 1.2 times your original bet. If you play with 6 decks blackjack pays 1.5 times your original bet. Blackjack pays less when you are playing with 1 deck in order to counter the advantage a player may achieve by keeping track of the card that have already been played. This type of adjustment is common in real blackjack games. This game is designed to simulate a real deck or shoe of card and the odds should be similar to using actual cards even though it may not seem like it.
