Extend path a little more than half way to the top left hole. The ball should cross over the two top holes, bounce off the rail and enter the top right hole.

Aim down center about half way and click.

Put the first dot on the 9th column at the 4th row. Count columns from the right and rows from the bottom. Center the dot carefully exactly on top the the triangle.

Extend the path so that the first ball is about a ball width away from the inside corner of the rail.

Extend path so that the first ball is about 5 ball widths below the bottom end of the right vertical rail that forms the entry to the top section. Center it on the center line of the rail.

Drop the ball at the bottom left corner of the Tee.

Extend the path so the lead ball is about 30% of the way between the tip of the bottom inside rail and the left vertical rail. The biggest gap should be at the tip of the bottom inside rail. Align its vertical position just slightly above a line projected from the bottom edge of the bottom inside rail. You just have to eye-ball those locations until you get it right. (The bottom inside rail is the one that goes across the top of the Tee.)

The ball should bounce of the left vertical wall, then off the right vertical wall, then hit the end of the top horizontal rail, and then on to the hole.

Extend the path is vertical and the first "ball" is about half way in the loop.

Aim the path to hit end of the top right inside rail. Draw an imaginary line between the bottom right and bottom left inside rails. Place the second dot on that line.

You will note that there is an isolate vertical rail. Place the second dot above the end of that rail along the vertical center line. The vertical position of the dot should be such that it and the two corners of the end of the vertical rail form an equilateral triangle above the top end of the vertical rail.

Line up with the left edge of the left tunnel so that the distance from the first dot to the tunnel is the same as the distance between dots.

Counting from the bottom.. put the first first dot on the fourth row, the 7th triangle from the left.

Place the 2nd dot on the inside of the top right rail lined up vertically with the top of the top left short rail.

Place the cursor at the center of the bottom rail on the inside edge and click twice.

Place the 3rd dot on the inside edge of the bottom rail aligned with the center of the isolated rail. The ball should curve around the isolated rail right into the cup.
