Your goal is to sink all of the single-tiled ships in the least amount of turns that Alexa has set out for you in a set grid . As a user, you can ask Alexa "what are my past moves" for a detailed description of tiles you have already fired at. You can, of course, attack tiles in hopes of finding one of Alexa's ships. To attack, simply say "attack B4" for example. The grid is comprised of 16 total tiles in a 4x4 orientation with columns labeled A through D and rows labeled 1-4. For example, some tiles have the following labels "A2", "D4", "C3", and "B1".
