Bowling is a very challenging game even though the game looks pretty easy since to play it, you just need to knock down the pins. But things like gutter balls (which are ball that go into the gutter, the giant 2 straight pathed holes in the floor seperating the aisles) make the game difficult no matter where you throw the ball. Throwing the ball too much to the left or right would guarantee a gutter ball, though if you use bumpers that automatically causes the ball to go to the opposite direction before it goes back into the machine and it at least takes down 1 pin. Though some things like strikes, that are bad in games such as baseball are good in this game. Strikes are when you throw the ball and take down all the pins and you can take down all the pins again to get a perfect score in that round and maybe the game if you position the ball right.
