What is an outside bet?
"Outside" bets are the wagers on the outside of the layout. These are the bets on red-black, odd-even, and high-low. If you place your chips in the even box and the ball drops into the number 24 pocket, you win. If it drops into 23, you lose. These bets pay even money. You can also bet on 12 numbers each in the "column" boxes at the far end of the layout. The first 12, second 12, and third 12 pay 2-1. If you put a $5 chip in the second column and the ball drops into number 17, you win $10.
