As the name implies, Tennix is a simple but fun game of tennis. It has a style similar to the classic Pong, but adding the rules of tennis and the difficulty of having to hit the ball at the right time, thus avoiding going out.
Tennix is a simple free and open source game, which does not require complex configurations to enjoy it. The only adjustment you can make is to change the color of the pitch. Learn to play tennis in the single player mode and when you're ready compete against a friend, in the multiplayer version, and show who is the best.
To give a different touch and take a bit of seriousness to this type of games, Tennix, has a somewhat different referee, a nice frog who will be responsible for monitoring and controlling that players follow the rules.
