In the beginning you can choose from three different tennis players (women and men). Each has its own attributes, so some of them might be better at defending while others are good playing close to the net, etc., but in any case you can improve these attributes independently.
The controls are simple and intuitive. Just have to slide your finger in the direction you want to hit the ball, keeping in mind that the longer you hold down your finger, the stronger the hit will be. You can also move by sliding your finger over the screen.
As you win games and tournaments, you can get lots of new items for your team: new players and also lots of different accessories.
Ultimate Tennis is a nice tennis game that's quite different from others in the genre. Part of why Ultimate Tennis is so good is its player customization, which is not very common in sports games.
