Adjacent Columns bets are not necessarily of more concern than other types of roulette bets. The chance of winning an adjacent Columns bet is the same as any other bet that covers a similar number of options on the table. However, it is important to keep in mind that adjacent Columns bets (such as betting on two columns at the same time) can be riskier because they cover fewer overall numbers on the table, which means that the odds of winning are lower.
