Roulette Tips Video Source & Information:

This is a roulette strategy where I will place eleven split bets, plus one straight up bet on one single number. As split bet pays seventeen to one, and as my total bets are twelve, for a winning spin on a split, I will win 5 bet units, and if the straight up number got hit,
I will win twenty four bet units. Now the main problem is, which numbers are going to be shown as winning ones.
And if I get a serie of lost spins, I will lose twelve bet units each time.
