I prefer full  contact ping pong. You need a ping pong table, paddles, balls, and some sort of barrier to put under the table. The object is to hit your opponent. To start one player serves and the other dodges (hopefully). Both players must be within feet of the end of the table for service. The ball does not have to bounce on the table. The ball can strike any surface, on either side of the table and playing field, any number of times.

So long as the ball stays in motion players can move anywhere on their side of the table. If a ball stops, the ball is given to the other player and he serves. Note: When a ball comes to a rest you have up to 3 seconds to pick it up and put it back in motion. Bouncing the ball on your paddle counts as being in motion. You may not deliberately and directly hit the ball under the table (thus the barricade). First player to the agreed upon score (13 and 21 are most common scores) wins. You do not need to win by two or more strokes.

Playing field note: Ideally his is  played in a somewhat confined space with walls on three sides to allow for the ricochet of ball. In such playing conditions you can deliberately bounce the ball off another surface to try and get it to go under the table. If a Player is hidden under a table and loses three consecutive points while thus hidden he forfeits the game.
