Wasn't so bad. (see pic)
How I chose these numbers: Pick that number hit 2 times within 20 spins, until 21 numbers....
I have so much to say...maybe I'll just leave it at this
I think you were farther ahead by pursuing the single number method you were inquiring about on another thread.
Still trying to help
Nice graph Ignatus :thumbsup:
The challenge is you're in a walk-in casino and you're not allowed to use a notepad, just a system from wrote memory. How could you implement that 21 number strategy?
