Start a session by recording the first 16 spins on a card. Use a casino card or a pre written card with the numbers 0 – 36 written on it and tick off the numbers as they hit.
You will most likely find that there are only 2 or 3 streets which have not come out. You may even find some double streets that have not hit.
For example if the numbers 7, 8, and 9 had not hit within the first 16 spins, that street would be one that you would bet on. If the numbers 10, 11, and 12 had also not hit within the first 16 spins, then you could bet on the double street 7 – 12.
Start betting on the streets or double streets that have not hit. Past experience with real spins (not using casino software) is that a win is very likely to be recorded within the next 5 spins. Therefore a progression with 5 steps must be used. It must be within the player’s bankroll capacity incase all is lost. It must also be tailored to be within the casino table limits, it must produce a profit which suits the player and be a reasonable profit based on the outlay of the progression, ie the risk to return ratio must be reasonable.
