Afternoon.
This is an EC system (GLC this ones for you!)
first of all we let two spins go by
R B
Those are our trigger couplet. Our betting opportunity comes when another red shows. Then we bet that it will be followed by a black, just like our couplet. If it does then it's a win of course. If not then we have lost one bet and need to wait for a black to appear and then rebet once a red appears thereafter.
Take this short sample:
B
R. This is our couplet. Next black shows we bet red just like the couplet
B. ok so here we bet red for the couplet to repeat
B. loss here. Now instead of keep betting red which could easily go missing for ages we wait for one to come and break the chain
B
B
B
R. Here is a red so now we wait for a black to find our couplet again
R
R
R
B. there's a black. Bet for red to hit
R. That's a win and our search for a couplet is no more (until the next bet)
B
B. and here's our new couplet - B B
And repeat over. I hope it's a solid bet selection. My progression would be 1 2 4 8 then
End session. Hopefully you can pick up lots of wins within these parameters
Cheers
