Two players, one hole at a time - 150 holes, each harder than the last. Beat a hole to unlock the next.
How to shoot: press and hold the mouse, drag away from the ball, then let go. The arrow shows the direction the ball will fly - the opposite way from your drag. Drag farther for more power.
Players alternate shots. If your shot doesn't sink the ball, it's the other player's turn - from wherever their ball is sitting. First to sink it wins the hole.
