Here's a little mini golf game where you must practice putter on the greens more difficult.
With the mouse, place the ball at the starting point, choose the direction and force of the blow by moving the putter over the ball (a white line used to display these two parameters) and click the right button to putter.

A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
