For small splits throw it in the middle. For the big splits throw it to the lift or right side and it will kick over the pins. For the strike for frist ball move arrow over just on side of the 1 pin.
There's a cool house rule in bowling: if someone leaves a 5-pin, anybody can raise their hand resembling the number pin they left. If the bowler misses the 5-pin, they have to buy a drink for everyone who raised their hand. You guys can do a variation of that for a fun challenge.
