im basing it on $1min to $500 max per column. 16 in one column can still be ok because this is based on colour for example 33 30 15 15 6 9 18 15 21 30 30 33 36 12 first bet on 30 bet on black columns 1+2 loss, 15 loss, 15 loss, 6 loss, 9 loss, 18 win, 15 win, 21 loss, 30 win, 30 win, 36 win, 12 win, and so on u would have to get 8 blacks in a row from column 3 for it to fail,can u workout the odds of this occurring and also if u can combined colour and column bets to test that would be great, if not u wont get a true reading or even just check out long series of numbers thanks for you're help spins
