You start with one bet. If you win, you start again with one bet. If you lose, you double your bet. Each time you lose, you double your last lost bet. Eventually you are bound to win. When you win you would recover all your lost bets plus one unit (or chip) profit against your initial wager.

The first problem is that most casinos have table limits which means that if you hit a losing streak you might not be able to continue doubling your bets. This means that once you hit the table maximum you will run into trouble.

Problem number two is that you are always betting to win just one additional unit so the return is low and the final problem with this system is that you can easily end up betting way more than you are comfortable with.

In its simplest form, you write down a series or a set of numbers; say, 1 2 3 4 5 6. Each number represents the amount in units or chips to bet. You bet the first and last of these numbers. In this example 1 and 6, which totals 7 units.

If you win, you cross out the two numbers and bet the next two 'ends' (the outside numbers). In this instance 2 and 5. If you win again you bet on the next two remaining numbers 3 and 4, and if you win that too, you would have made a 'coup' or completed one game. Then you start all over again.

If you lose, then you add that one number to the end of the series. Say you lost your first bet of 7 units (1 + 6). Then you add number 7 to the end of the series to look like this: 1 2 3 4 5 6 7 and your next bet would be 8 units (1 + 7).

The problem with this system is that you can again easily end up betting large sums of money even if your initial bet is small and once again the return is low.
