"Sonar Search is a classic game of Naval Battle Strategy in which two opposing and a certain amount of luck are required in order to be the first commander to sink all five of the opposing ships.

Sonar Search is provided in two versions: A one-player version in which the player attempts to locate a hidden fleet before running out of ammunition; and a two-player version in which each player tries to sink his opponent's fleet before his own fleet is destroyed.

When you fire a shot and miss you will hear a number of Sonar "Pings." These "Pings" are a result of an ever widening invisible square which radiates from your firing coordinates pinging at each step as it expands outward. The pinging changes tone and stops when this expanding square
contacts an enemy ship.

By counting these pings you can judge the distance an enemy ship is from the last location fired and by "remembering" your previous search you can determine his approximate direction. By learning to plot your sonar you can add a new depth both in interest and skill to this already
fascinating game."
