Simply put, wall ball is practicing your soccer skills using a wall to stop the ball and to return the ball to you.As a coach, I believe that wall ball (also known as “wall soccer”) is one of the best ways for players to train. It is especially effective for practicing passing, kicking, and receiving skills, and is particularly useful because wall ball can be played alone – as the name implies, all that is required is one player, a ball, and a wall.
Almost any solid wall will suffice. I use the term “solid” wall because it is generally not a good idea to use a wall with windows or such – even the best players sometimes make errant kicks. Also, most chain link and iron fences can damage balls and will produce unnatural return bounces. Still, you can usually use racquetball or handball courts, wood fences (providing they do not splinter), cinder block and brick walls, and even many dirt mounds or embankments, etc.
You can also use any ground surface, though the ideal surface is grass or a surface similar to the type you normally play games on.
