The Betrayer's Game: All In on Revenge

The night before her engagement party, Natara Sadler walks into a bar and finds her fiancé Jace Fuller registering a marriage with his best friend Winona Sloan. Neither of them hides it. Winona mocks her and Jace says nothing, and instead of leaving Natara sits down at their table and asks to join the dice game they are playing. She plays badly on purpose, losing small rounds and letting them believe she has never gambled. Winona keeps needling her to raise the stakes and Jace goes along with it, so the bets climb until the table is playing for everything the two of them own. On the last roll Jace turns up twelve, the highest score possible, and then Natara shows her own throw.
