Only the best players can beat these unwelcome visitors in a tennis match, so grab your racket, flex your muscles, and put on your sweatband. The fate of Earth is in your hands, so you better start scoring those points!

Crazy Tennis offers different gameplay from the other tennis games you’ve played. Normally, you would compete against another tennis player, but in this game, you have to join an exciting match against various aliens. Luckily, your opponents have agreed to play on your terms and the general rules of tennis apply in these matches. As the player, your objective is to win each match with your character. Be prepared to run around and swing your racket constantly because these matches are extreme! The game has simple controls. To move around the tennis court, use the arrow keys. To swing your racket, you have to use the space key. You also have to use the space key for service shots. Press and hold the space key to adjust the power of your service shot and use the arrow keys to aim. You can choose two different characters to play and 3 different aliens as opponents. Each of these characters has different stats: strength, speed, and precision. Try them all and choose the one you like best. If you think you need some practice before you start playing the actual game, you can join the tutorial to test and improve your skills. Once you’re ready, you can start a simple match. The game has 3 different difficulty settings and each of these settings changes the stats of the characters. How well will you perform?
