If the Bulls lose the game or win by fewer than seven points, they fail to cover the spread (meaning Clippers bettors cash their wager). What if Chicago wins by exactly seven points? It's called a push, and all bets are refunded (no winner, no loser).
If the shooter rolls any seven before repeating the point number (a "seven-out"), the Pass line loses, the Don't Pass line wins, and the dice pass clockwise to the next new shooter for the next round.
