Pick a Side
Depending on your handedness, you want to be on the right or left side as a beginner because most people will naturally curve the ball slightly when making the throwing motion. If you're right-handed, move a couple of pins to the right -- and vice versa -- so when the ball curves, it goes through the middle and takes out many, if not all, of the pins.
Straight Corner Shots
If you've practiced bowling and have perfected the straight on shot, there is a sweet spot where you can get a strike every time. Go to either of the far corners and line up the dotted line halfway between the very front pin and the outermost pin on the second row. If you bowl it perfectly straight, you'll get a strike.
Beat Splits
Splits are difficult, but not impossible, to overcome. If you get a split, your best bet is to try to curve the ball so it hits the side of the pin away from the other pin to create a ricochet effect. For example, you would want to hit the left side of the left pin so it bounces over and hits the right side of the pin on a split.
Slow Roll on Consecutive Pins
If you have pins that are lined up in a row on your second attempt, bowl more slowly than normal to take out both pins. Otherwise, if you bowl quickly, the ball will bounce off to the side of the pin that you hit, and you will not be able to knock down both pins.
