A popular system strategy at playing Roulette is the Neighbour Bet / Neighbor Bet as outside bet strategy. Depending on the latest result you punt your jetons on the same section, the actual latest result and its neighbour pockets. The idea behind this strategy is that a dealer does monotone spins and the probability exists that the ball lands once again in the same pocket (Double Spin) or the fields around it – you may decide about the range.
Have a look at the visual example below with the Neighbour Bet by using 5 pockets in total.
