This is known as the cancellation system. Pick a series of numbers, say 1,2,3,4,5. Your first bet is the total of the two numbers on the end, or 6 units in this case. If you lose it, you cancel out the 1 and the 5, add the six to the end of the series and bet the 6 and the 2, for a total of eight units bet. Lose that one and you add the eight to the series, cancel the 2 and the six and bet a total of 11 (3+8) and so on. If you win, you proceed to the inside numbers until they are all cancelled out. Again, a loser, but an insidious one.

Some gamblers believe that you can recover your losses by doubling your bet every time you lose. This is known as the Martingale system. The idea is that when you win, the win will be big enough to cover your previous losses. There are two problems with this system: You may run out of money before you win. You can only double your bet so many times because of table limits, and so occasionally you will hit the table limit before winning – and this will be very expensive.

the first roll of the dice in a betting round is called the "come out" roll. Pass bets win when the come out roll is 7 or 11, while pass bets lose when the come out roll is 2, 3, or 12. Don't bets lose when the come out roll is 7 or 11, and don't bets win when the come out roll is 2 or 3. Don't bets tie when the come out roll is 12 (2 in some casinos; the "bar" roll on the layout indicates which roll is treated as a tie)

Button Descriptions Roll: Clicking on the Roll button after placing a bet starts a new round. Repeat: Clicking on the Repeat button will repeat all the bets made on the previous round that can be validly placed now. Clear: Clicking on the Clear button removes all the bets on the table that can be removed. Most bets can be removed, added to, or deducted from at any time. Exceptions would be the pass and come bets, and you cannot exceed the maximum bet on the odds. Table Min/Max: Look here to find the minimum and maximum total of the bets allowed. Bet Regions: When moving the cursor over the bet regions a yellow “tag” will appear that gives the name of the bet, the current amount placed for that bet, and the minimum and maximum amounts that can be placed on that bet. If a green highlight appears in a region, that indicates this bet can be added to (changed) If a red highlight appears, this bet cannot be increased (but sometimes can be removed)
