A special system strategy at playing Roulette is the (Red) Snake bet as outside bet. There is a debate about the point if this is a proper strategy, because it’s a bet on a group (segment) of specific wheel pockets in the end.
The player places the chips (American Roulette and European Roulette as well) on the red coloured pockets: 1 – 5 – 9 – 12 – 14 – 16 – 19 – 23 – 27 – 30 – 32 – 34
The shape of this order of the chips on the fields gives the Red Snake its name. Have a look at the visual example below.
