So simple It must have been done before

[Jeromin]

A very simple bet: on the last number. That's it. One unit per spin.. After 34 losses, increase to  2 units. Then to 4 units, then to 8 units. On win, start over.  BR: 510u. I did a preliminary test over a few hundred spins, with some Hamburg actuals, and it didn't seem to take more than about 40 spins,usually a lot less, for a number to repeat in the next spin. Naturally, it's a long progression, so the appearance of success is to be esxpected.
Still, I'm be curious to see how often it fails, and what's the longest a number of spins without a number appearing twice in a row.

Hmm, sounds adequate on the surface, but might be a tad boring in reality.

Besides, you could just increase the bets by 1 unit to avoid a loss (instead of doubling up) and you could run this out 130 spins for $750 and have a profit on any hit!!

Running it as a 1,2,4,8,16 progression (for profit) gets you out to 108 spins for $576.

If you think you can hit it in 100 spins, that's the one to go for and run the 1,2,4,8,16 progression.  At spin 100, it'll be $448 if you don't hit.

I know I've sat there and watched green come up a whole lot more than once every 100 spins!!

If you've got the time, they've got the money!

Single numbers can sleep for 500 or more spins.

Single numbers can sleep for a long time, but what this bet  is on is an immediate repeat of the last number. E.g., 3 19 4 0 27 27. So we bet on 3, then on 19, then on 4, then on 0 then on 27. 27 wins. If any of them sleeps for 500 spins it's irrelevant, as long as one of then repeats in the next spin every 135 spins or less.
I want to know if it works, not if it's fun. At worst, that's what bots are for.
Let's say the progression  gets to the 103rd spin. We increase by one unit instead of doubling up. So it's 3 units. It wins: The bet pays 35 to one, 35 units x 3 =105 units. I recoup 105 - [34+(34x2)]= 3 units. A win in the next spin yields no profit, and in the next 32 spins the losses increase with every spin. If I double up, I make a positive but decreasing profit in everyone of the 34 spins.

Yes Yes yes

This is good. If its not Why not then say that its so good don't play the last number. The last number can and will repeat. Just like the last dozen, column, colour,...

Four groups of numbers 1-9 / 10-19 / 20-29 / 30 - 36 The latter are only 7 numbers add the Zero to it. Then its chasing the last number with the group on the table.

This is not boring. The hits are quicker than you think. Play from side / streets and play and extra method inside, something  you like. 1-9 = 3 streets 10-19 = 4 streets add 20, 21 / 20- 29 = 4 streets add 19, 30 / 30 -36 = 3 street add first 4 for Zero.

If its not good then you know what to do - Don't play it play the rest. You will win.
