Hi, this are systems based on inside bets (24 and 16 numbers).
For European Roulette Wheel , but can be done also for American R W .
Please test before play for real money, this are not HGs or so ,
but in my opinion/experience are better then outside bets.
I do use this ones in real play, also other inside methods
but bet only 4 numbers or 6 numbers or 9 numbers(will post some next year).
good luck
Here are some 12 inside numbers (nuke or triangle)groups I use sometimes( see excel file).
I bet for the last to repeat after some triggers, or I bet one active (hot or middle hot) group
using a few progression steps.
cheers
