Simple system. No brain needed. Ive had some success (luck!) playing this for fun. The basis of this system I call "single scoop (one number), double dip (betting it twice)" is all about chasing the last number hit. Often I will see a number hit twice in a row. Id love to know the odds of that. Its just something Im doing for fun right now, not fully developed but Im sure it could be made better. So here it is...

$1 bet (1u) on the last number that hit. If you dont win then immediately bet the next number hit. Until you hit twice in a row and win.

A simple progression...

1u bets on the first 10 numbers

2u bets on the next 10

3u bets on next 10

4u bets on next 10

progression levels would look like this if written another way...

1111111111

2222222222

3333333333

4444444444

5555555555

6666666666

7777777777

8888888888

9999999999

...and so on. SIMPLE.

The longest Ive recorded so far is 104 bets before hitting the same number twice in a row. I started with 10,000 bankroll but maybe less is needed. Again, not really developed yet

I originally started this with a martingale progression but you could never really go 100x or more. I could do a more conservative progression such as 111111111111111111111111111122222222222222222333333344444555666,etc but I was looking for something simple enough I could easily remember so 10x for each unit and then move down to the next level.

Heres an example of play...

12 = 1u

18 = 1u

36 = 1u

11 = 1u

4 = 1u

21 = 1u

28 = 1u

4 = 1u

17 = 1u

1 = 1u

32 = 2u

0 = 2u

18 = 2u

11 = 2u

16 = 2u

16 =2u WIN!

Again... needs lots of work. Progression? Bankroll? Maybe its already a bad system if theres data of two numbers hitting twice in a row can go 500 spins. Unfortunately I dont know that info. But I see all too often numbers hitting twice in a row so why not trying playing it somehow
