Upgrading your equipment is essential in Ping Pong Fury, as this will improve the attributes for the given item. Each different type of equipment (Blades, Rubbers, Balls and Shoes) has different attributes, each improving the gameplay.
Speed is one of the most important attributes in the game, as this affects how much power you can apply to each return. The higher the speed, the faster the return.
As you play harder opponents, you want to have more control over your shots. The Control attribute determines how accurate your returns are.
This is another really important attribute as you progress through Ping Pong Fury. The Spin attribute controls the spin you can apply to the ball on a return shot.
Having a strong service can even win games, so upgrading Serve Power will be important to your game. The higher the Serve Power, the faster you can serve that ball.
Improving your Serve Spin is very much needed if you're looking for aces. The higher the Serve Spin, the more spin that you can apply to the ball on a serve.
Improving your Agility is a necessity as you play Ping Pong Fury, as this affects the speed at which your player will move around the table. The higher the Agility, the faster the camera movement to get across to return or step back to lob.
