This is doing good after testing 200 spins; and quite stable (it makes about 25 units per 100 spins).
Bet
1u on a Doz & 1u on a Col
Bet selection: SAME as LAST Doz & Col
If both sides (Doz & Col) lose 2x in a row all at the same time, bet on the NEXT Doz/Col that comes after the last hit Doz & Col.
Example of what I mean by NEXT Doz/Col:
Last hit Doz was Doz2 (13-24), the next Doz will be Doz3 (25-36)
Last hit Col was Col1 (1-34), the next Col will be Col2 (2-35)
Last hit Doz was Doz3 (25-36), the next Doz will be Doz1 (1-12) (we go around)
Last hit Col was Col3 (3-36), the next Col will be Col1 (1-34)
Must be -4 or more to start progression (no separate progression)
Progression: 2 - 3 - 4 - 6 - 8 - 10
Go back down in the progression as you win.
If a win brings your total balance in the plus (+) and your next bet is more than 1u, bet half that amount.
Ex: your next bet is 4, then instead bet 2.
* If a Doz or Col repeats 3x in a row, go same as last on both sides.
This is in essence the same system that Jordan proposed the other day. The only difference is that you are combining the bets as a single system allowing a win in either field to count as a reset for both bets.
Again it's the progression that kills you right form the start. Wins do not make up for cumulative losses.
For a progression to work in this case you would need to bet in each field
1-3-9-27-81
The win would always be 1u.
Hardly worth the downside risks (-121u)
Monte Carlo
I'll test 1000 spins MC. If it makes it, i'll take it to the casino. If not, then it was just another idea. ;)
