Rally Masters is a simple and fast paced tennis game where the goal is to keep the ball in play for as long as possible. The player controls a racket and moves it up and down to return the ball. Each successful hit increases the rally score, which measures how long the player can keep the rally going.

As the rally gets longer, the ball moves faster, making the game more challenging and requiring quicker reactions. The direction of the ball depends on where it hits the racket, allowing players to aim their shots and control the game.

The game includes a single player mode against an AI opponent and a two player mode for playing with a friend. The AI returns the ball with slight variation, making each rally feel different and less predictable.

Corner zones on the court act as a separate scoring system. If the ball lands in these areas, the player earns a corner point, but it does not increase the rally score. This encourages more precise and strategic play, as players must balance keeping the rally alive with aiming for accurate shots.

The aim is to maintain the rally for as long as possible while also collecting corner points to demonstrate both consistency and accuracy.
