1) In knowing that (Each Corner Of Every Twelve) Surrounds the Double 00, including 8 and 29, you have just memorized 1/3 rd of the wheel.
2) "Favorite FOURS" 5-17-20-32 (1/4 turn from the O) with 2-14-23-35 (Next to the 0) all located in the middle row are your next set of "Hot Spot Numbers"
3) Second Dozen numbers are all located every other number 1/4 turn from each of the 0-00's.
This is good to know when you decide to play roulette during busy nights when everyone floods each number with chips and covering the location.
