None of these systems work. This is one of the most widely used systems of betting. The betting strategy, multiplicative in nature, requires the gambler to double his bet after each loss until he wins, then he starts over. For example, suppose the gamble is at roulette. The gambler bets one dollar and loses, bets two and loses, bets four and loses, bets eight and wins.
Casinos have betting limits at the various games.
A simple linear system named after the eighteenth century theorist Jean le Rond d'Alembert. He believed that if a fair coin landed on heads for a long run, that tails was more probable. In the system bearing his name, you raise your bet by a fixed amount if you lose and lower it by a fixed amount if you win. A sequence of numbers, say 1,2,3,4, is chosen. The first bet is the total of the two numbers on the end, or 5 units in this example.
