Because the rules of snooker stipulate that when there is only one black ball left on the table, the bag falling or foul caused by hitting the black ball will directly lead to the end of the game. Please refer to the following referenced rules:
Four, the game is over, the venue or the game is over.
1. When only the black ball is left, when the batter scores or fouls first, the game is over, unless:
(1) At this time, the scores are equal, and:
② The integral is different. (This situation is aimed at the system of comparing points. )
2. When two situations described in 1 occur,
(1) The black ball should be put back in its original position.
② Players of both sides must draw lots to decide the batting order.
The next player must start with the ball in his hand when hitting the ball.
(4) When scoring or fouling again, the game is over.
In other words, even if the opponent fouls the black ball, you add 7 points and the game is over. The two sides directly compare the scores, and the winner is the one with the highest score.
