Xeres puzzle hints: solitaire ball jumping

This page contains hints that may spoil the puzzle.

Hint 1: It is a lot like checkers, but played alone. You can only jump over one ball at a time, and the ball you jump over disappears. The goal is to finish with only one ball left.

Hint 2: Try to clear the balls in the upper corners first, or you may not be able to remove them later.

Hint 3: Group the balls as you jump. Do not leave too much space between them, or you will not be able to remove them later and will have to start over.
