It is one of the most funning sport games I have ever played. Compared with other games, it's quiet difficult, but I am crazy about challenge! The game uses "ball" to play career games and shop and You can buy shoes and racket to improve your speed and power. AI seems a little ob if you don't shop, but as I said, I love challenge. By the way, you can also play with other players to earn balls, but there are only 5000 other people who are playing this game, it might take some time to search for an opponent.(o>▽<)

UPDATE: This game is a total joke. I've gotten good enough to win two points per match against the top guys. It's tough to beat perfection. Deleted the stupid game. This game has very good game action. It's fun to try to improve and beat guys you previously weren't able to. That said, as other reviewers have pointed out, the game quickly becomes impossible. No matter how perfectly you strike and direct the ball, your opponent will hit it back harder and put it right on a corner, out of your reach -- like trying to outplay a highly skilled brick wall. You quickly max out and realize you can't beat any more opponents -- and you know it within two or three points of a given match. I've rejoiced at successfully scoring one point in an entire match! One-on-one online mode is too glitchy to be fun. The ball speeds up and slows down every point. Great idea, fun game but recalibration is needed.

I enjoy playing this game when it works right. Unfortunately the game freezes when the opponent doesn’t hit the ball over the net. It should default to awarding me the point. On a serve it should either allow the opponent a second serve attempt or award me the point. But in each of these cases the ball just rolls on the ground and nothing resets. I end up having to quit the game which costs me points!!!! This is terrible. Can’t believe the developer didn’t find these bugs. It only started doing this after the last update. I’m on an iPhone X. Shouldn’t matter regardless, but I couldn’t even play this game for six months after I got my iPhone X because the developer neglected to update to update the app. Hope the bug gets fixed soon.

The gameplay and ball striking here are solid, but the difficulty levels attached to this game are extraordinarily frustrating. At the lowest levels (training), the opponent will consistently approach the net, hit the ball past you, hit aces on serves; all the while you can do none of those things. The only way to even win a point is to pound the ball from side to side and hope you can push it past the opponent. Past the tier 1 opponent, you won't be able to, and at least half your shots will go wide anyway. The computer, of course, will never miss wide. Winning games, sets, matches is completely out of the question. Don't take my word for it, please give it a shot. If you don't find this deeply unfair and unwinnable, I'll eat my words. And the menu graphics and layout are dated by easily 20 years.
