The Don't Pass is the opposite of the Pass Line. Where one wins, the other loses.
Don't Pass Lay Odds
Lay Odds are an extra bet you can add to your Don't Pass that gets paid True Odds.
Don't Come
Don't Comes are just like mini Don't Pass bets. It's always betting against the next Point number to roll.
Don't Come Lay Odds
Just like the Don't Pass, you can add Lay Odds to your Don't Come bet which gets paid True Odds.
