Sorry, just noticed this - I still play it, but not often.I think this looks alot like the code 4. Similar but an easier twist
I did make some modifications working the dozens and columns together into the charting
It's "so-so". lol
Instead of (before) recording dozens...1,2,2,2 and then betting against 1,2,2,2 happening again,
I moved towards including the columns also ('A' 1-34, 'B' 2-35, 'C' 3-36) which gives me something that looks like : 1A,2B,2C,2B (for example) - and now I can bet against that happening again (amazingly it almost never does).
Are you using a progression or flat betting?
