To get the 7-10 split easily, first, you must create a new bowler. Set up the bowler's stats so that it has 20 strength, 19 accuracy, and 0 curve. Now, at any lanes, select the 20-pound ball "Bone Crusher." Now, line up so that you're completely at the right, both bowler's feet and ball alignement. Now, throw the ball at max power (let the meter go beyond the green), and then hit accuracy as close to the green as you can (as long as it is close, it will work). The ball should hover just next to the gutter and the ten pin should bounce off the back-board and into the 7 pin. This is the easiest way to unlock the secret bowler, "7-10."
