Parlay 31 Roulette System

A Parlay system is the simplest of all Roulette Systems which has you on a winning wager, leaving some or all of your winnings on the table for the next spin. This is also referred to as 'Letting it Ride'.

Parlay 31 builds on this idea but layouts progression for your wagering units. The Parlay 31 progression looks like this: 1, 1, 1, 2, 2, 4, 4, 8, 8 which when added up equals 31 (hence the name parley 31). The size of the unit matters for this progression, since it is important to be able to parlay 8 units your units cannot exceed 1/16^th of the table's maximum or you will not be able to complete the progression. Setting you unit to the table minimum is perfectly fine.

To start we will wager 1 unit on a wager of our choice lets say the 1^st dozen. If we win we collect our winnings and our wager stays at the same level. Unfortunately we lost our first spin and the 2 spins that followed. With each loss we step to the next number in our progression, so the first three steps are one unit each. Our forth wager will be two units which we win. Unlike other systems we do not reset back to the start of our progression but continue to wager the same amount in this case two units. We continue up through the progression until we have completed it with a win on an eight unit wager. This will end our session and we can start over at 1 unit.

Since this System has you increasing your wagers on loss it is known as a negative progression system. Using a Negative Progression Roulette System carries different risks from other Roulette Systems and it is important to know when to stop the session before you deplete your bankroll before you need to.

Kent (21/11/08 12:53 pm)This is a good article, but here is possibly a better bet:
Betting on "the first dozen" covers less than one third of the board, so the chances of winning this bet once is less than one third, and the chances of winning two times in a row is less than one in nine; only about 10%.
So a better bet might be to cover the red or black, or odd or even, plus put one chip across both zeroes green numbers, so you have more than a 50% chance of winning each time. Simpler than this, and with a lower house edge of 1.4% instead of 5.26%, is to place your bets at the craps table (dice) on the Don't Pass line (or on the Don't Come, if you don't like betting directly opposite of all of the Pass line bettors at the table).
You continue up the progression until you have 2 wins in a row, at which point you have a profit, and then you can start over with one unit again.
Here's the profit at each level, with 2 wins in a row:
Step 1) Bet 1: win, win = 4 units, with a 3 unit profit
(if lose, or win, lose, then go to the next step)
Step 2) Bet 1: win, win= 4 units, with a 2 unit profit.
Step 3) Bet 1: win, win= 4 units, with a 1 unit profit.
Step 4) Bet 2: win, win= 8 units, with a 3 unit profit
(a 6 unit gain, minus the previous 3 losses)
Step 5) Bet 2: win, win= 8 units, with a 1 unit profit.
Step 6) Bet 4: win, win= 16 units, with a 5 unit profit.
Step 7) Bet 4: win, win= 16 units, with a 1 unit profit.
Step 8) Bet 8: win, win= 32 units, with a 9 unit profit.
Step 9) Bet 8: win, win= 32 units, with a 1 unit profit.
(24 units of profits from this step, minus 23 units of previous losses from progression steps 1 through 8).
The chances of a win, win NOT happening at each step, against a 1.4% house edge is 75.651%, and the chances of losing every step, 9 steps in a row, is 8.159%, or about 1 in 12. So, every 12 times you try this, on average, you will lose your 31 units, and the other 11 times you will win 1 to 9 units, depending on which step win-wins.
All betting against a house edge loses in the long run, but this will give you the best chance of winning, or at least playing a longer time and having fun, in the short run. If you don't mind losing 43 units, you can add a step and do a progression of: 1,1,1,2,2,4,4,8,8,12, with a profit of 5 units if the last step win-wins.
