I have been trying for a long time but can't figure out how to play this game. Is there anyone who can give me some ideas?

The rules of the game are simple: jump over a piece to remove the jumped piece. Try to remove all pieces except one. Drag a piece to an empty space to move it. The target position must be exactly two holes away from the starting piece, the directions must be orthogonal, and there must be a piece in the middle hole. But I always end up with a few pieces that are far apart and can't be solved. What's the idea of playing this kind of game?
