A couple gimmick games I’ve played.
In 8-Ball, my opponent gets the break and only has to make the 8. So, if he makes a ball on the break, he can shoot directly at the 8 and any turn at the table there-after he shoots at the 8. Otherwise, I have make all the other balls, in no particular order, pocketing the 8 last.
Played 9-ball with a guy where the rails were his pockets. That was exciting.
Another 9-ball game I played where I spotted my opponent the 7, 8 & 9, but he could only shoot them in one of the corner pockets and I could not shoot any of them in his pocket. I ended up not liking this game.
He spotted you in that eight ball game
