GAME_INSTRUCTIONS

The objective of this task is to build a battleship game for two players in Ruby in a terminal. Please read all the instructions before you start.

⚠️ You should not require any gems aside from ones to help you write any tests (rspec, minitest...). ⚠️

• Each player will look away from the screen when the other player is placing their ships. You don't need to consider privacy.
• One grid per player.

• We prefer a working game with some rough edges to an unfinished masterpiece.
• Your code should be tested by automated tests as much as possible.
• Quality matters. Focus on separation of responsibilities, readability, and modularity.
• Explain how to run your game (and the tests) in a README.md file in the root of your project.
• Software is never really finished. Think about how you'd evolve the codebase if you had unlimited time.

The game is played on 5x5 grids. Your first task is to set the game up:

• Players have 2 ships each to place on their grid. A small ship (3x1 size) and large one (4x1 size)
• Players are asked in turn to place their ships on their board (ie: interactively)
• A ship can't be placed out of bounds nor on the same space as another ship.

Once all the ships are placed the game begins! Now you have to set the gameplay mechanisms up:

• Players take turns to shoot at the opponent grid one after the other by selecting coordinates.
• Each shot receives a Hit, Miss or Sink response.
• The winner is the player who sinks all of their opponent's ships first

At this point the game works and we'd like some improvements of some of its mechanisms:

• Starting player is determined at random.
• If a shot attempt is made out of bounds the game offers a retry.
• When the game is finished it gives the option to play again.

This part is here to spice things up! 💥 We'd like to have these features added to the game:

• Ships can now be placed diagonally.
• If a player misses a shot 3 times in a row the game gives a hint of a valid shot.
• The game now works in a "Best of 3" match mode:

If player 1 wins the first game, the match is not over yet because player 2 can still win the 2 other games and win the match.

If player 1 wins first 2 consecutive games, then the other player can possibly win 1 game maximum, which is not sufficient to beat the 2 games won by player 1.

If each player won 1 of the first 2 games then the third game is played. Whoever wins the third game is declared winner of the match.
