Welcome to BattleTaire! This is a command-line version of the classic Battleship game, implemented in Ruby. The objective is to sink all the ships placed on a 10x10 grid by making guesses.

To run the game, you need to have Ruby installed on your system. You can check if Ruby is installed by running the following command in your terminal:

ruby -v

If Ruby is not installed, you can download and install it from ruby-lang.org.

Clone the repository or download the game code to your local machine.

Open your terminal and navigate to the directory where you have saved the game code.

cd path/to/your/directory

To start the game, run the following command:

ruby battleship_game.rb

When the game starts, you will be prompted to enter the maximum number of tries. The number of tries must be between 17 and 100. This is because you need at least 17 tries to potentially hit all the ship squares, and the grid size is 10x10, making 100 the upper limit.

Enter the maximum number of attempts (must be between 17 and 99):

Enter a valid number and press Enter.

Once you have entered the maximum number of tries, the game will display the 10x10 grid. You will be prompted to enter the row and column number for each guess. The grid uses numbers for both rows and columns.

For example:

Enter row and column (e.g., 3 4):

Enter your guess in the format row column and press Enter.

• If you hit a ship, the game will display "Hit!" and mark the grid with an X.
• If you miss, the game will display "Miss!" and mark the grid with an O.
• The game will show the number of attempts made and the number of hits after each guess.

• You win the game if you hit all the ship squares within the maximum number of tries.
• You lose the game if you run out of tries before sinking all the ships.

At the end of the game, a message will be displayed indicating whether you won or lost.

Congratulations! You've sunk all the ships in X attempts.

or

Game over! You've used all X attempts.
