This is a stark comparison to roulette outside bets, as the outside bets are going to be bets on red or black, odd or even, high or low, and other large group bets. Individual numbers, small groups of numbers, and even fairly large groups of numbers, all fall into the roulette inside bets category. Inside bets are going to be your bets that focus on numbers. And while their location on the layout is how they are grouped together and how they got their names, inside and outside bets are actually quite a bit different despite looking very similar on the layout.
