Free tennis games are online tennis games that include table tennis, doubles tennis and even futuristic twists of the tennis game. If you play tennis you may find the skills of the mouse and keyboard are similar to the real game. The most important factor of the game is balance, not the motion of the stroke itself. What's the use of a great stroke if you can't get to the ball and position yourself properly? That's why players are sometimes baffled when players that play ugly actually win against good players. Most free online tennis games involve balancing power and time on the serve, while managing movement on the forehand and backhand.
