This is another old system. It has it's own name "The Labouchere or cancellation system".
It is certainly better than the Martingale, but it is still a loser. No system can overcome the house advantage.

The problem with the Martingale system is how the amount of the bet increases exponentially. The problem with this system (even if there are no table limits) is that it is difficult for most of us to bet even $128 on red or black. And this is only after 7 losses.

The modified method consists of starting with a sequence of $1, $2, $3, $4. The bet consists of betting the sum of the first and last numbers. In this case the bet would be $5. If you win, you cross the first & last #s off, and you bet the sum of the "new" first and last #s (2&3). If you win, you have won $10, and start with 1,2,3,4 all over again.

Lets say you lose. You add your last bet onto the sequence and again bet the sum of the first & last bets:

1,2,3,4,5 if you lost the first bet. Now bet 1+5=6. Lose again. 123456. Now bet $7. Let's say you win. Cross off 1st and last #s.
New sequence is 2345. Now bet sum of first and last ($7). Now consider consecutive losses from here: New sequence is 23457, then 234579 (adding the $9 loss), then 234579,11 then 234579,11,13, then 234579,11,13, 15 then 234579,11,13, 15,17 then 234579,11,13, 15,17,19. After these 7 consecutive losses, your next bet is $21 (the sum of your 1st & last #s). In the Martingale system your bet after 7 consecutive losses would be $128.

I made a slight error when i stated to cross off the 1st and last # after the win (above); new sequence should have been 2,3,4,5,6. However you get the idea.

Now let's say you have normally lousy luck from here on, and win only 2 of every 5. You will eventually wipe out the whole sequence since for every loss you add one number, but for every win you cross off 2 numbers. Every time you wipe out the whole sequnce, you win an additional $10. Whereas every time you win in the Martingale system, you pocket $1.

If you believe that roulette is a fair game, and that each spin is independent, none of these betting systems will increase your expected return as a function of total money bet.

If I use a betting pattern of 1,4,9,3,2,10,40,40,27, that is no better or worse than a martingale or cancellation system from an expected value standpoint. The difference is in the variance.

Independent trials means just that. There are no streaks or patterns or hot tables. There are merely successions of independent trials.

If you want to test a roulette system to see if it is a postive expectation, you should be able to use in on every possible wager. If my system is bet 1 unit on a number to start, if it doesn't hit for 10 spins, bet 2 units. If it doesn't hit for another 10 spins, bet 3 units. If it doesn't hit for another 10 spins, bet 4 units until it hits. Whenever you hit, go back to 1 unit. My guess is if you bet every number, you will very quickly get to the expected value of the wager, -5.26%.
