When playing blackjack, or any other game for that matter, try and keep records of your visits. Recording the casino, shift, number of players and number of decks used in blackjack. For slots record the number of the machine players, amount of time played and amount of coins you started with. The amount won or lost will help you plan future trips. You might be surprised to find your records might state you have won over the long haul when you thought you lost at that specific casino. The records will help analyze your game. It might tell you how you do in a single or shoe games. It might reinforce that some casino slots are losers then others. Review this data before each trip and see if it doesn't help.
