Karen is playing Connect 4 with Sam. As they play, 4 of a color are lined up in multiple places without the game ending. During the cut where Pete is answering the phone, all the placed pieces appear in only two columns. Another cut attempts to recreate the first board state. When Pete leaves, a close-up of the game shows a tied game.
The connect four board also shows that 'red' won the game long before they stopped. There's no way the board could fill as it had and that not have happened when you see the diagonal line of six.
The Connect 4 game board has an unequal amount of red and yellow markers in play. 23 red and 19 yellow. For computer based play, the number of markers should be equal on both sides.
