Sonar Patrol

The idea behind this interpretation of Black Box is that you are a sonar operator tasked to locate and destroy a group of five enemy subs that have entered your patrol sector (which is imagined as a 8x8 grid).

You will have the ability to launch depth charges to sink the enemy subs, but first you have to locate them.
To do so, you fire sonar pings into the grid from the perimeter.
Depending on where the pings enter and then exit the grid, you have to determine where the subs are located, but remember to use your pings carefully, because you will have only ten available.
