Multiplayer Roulette
When players aren’t betting simply even/odd or red/black wagers, then it can become a little more complicated to bet against someone. If a player is betting on a single number, then you can bet on the opposite color and opponent even/odd so that your wins are always their losses. The idea is that you want to line things up so that you’re going to be winning as much as possible when your opponent loses. However, you want to avoid making bets that are too complicated to be practical. An example of over-complicating your bets against a player who is betting on a single number would be to bet on every single other number than the one your opponent has bet on.
The same ideas that we have presented here for betting against players in multiplayer roulette can be used to bet along with another player. You don’t always have to make the exact same bets to play along with a player, but you should share some of the same winning numbers.
