Battleship-CLI Instructions

Type help and hit return at any time during gameplay to show these instructions.

Other helpful commands:

• Type show score at any time to check the status of the game.
• Type quit or q at any time to quit the game.

Settings:

• NOTE: If your terminal does not support Emojis, please disable Emojis in the settings menu.
• For a more challenging game, you can choose a larger board size.
• You can also adjust the computer's skill level.

How to win:

• Each player has a battlefield represented by a 10x10 grid on which they place 5 ships, hidden to their opponent.
• The goal of the game is sink all of your opponents ships! A ship is sunk when it is hit once for each space it occupies.
• In other words, a submarine, which occupies 3 spaces, is sunk after being hit 3 times.
• The 5 ships occupy 17 total spaces, so the first player to register 17 hits wins!

Gameplay:

• To play, follow the prompts to configure your five ships in any pattern you'd like (diagonal placements are not allowed).
• Valid configuration instructions include a ship name, a starting coordinate (A1-J10 for default 10x10 board), and a direction (right, left, up or down).
• For example: submarine e3 up or carrier j7 left. Ships cannot overlap, and you must stay within the bounds of the board.
• Once both players have configured their ships, the race is on to sink your opponent's ships before they sink yours!
• Fire torpedoes at your opponent's ships by guessing coordinates on the 10x10 board.
• Rows are represented by the letters A-J, and columns with the numbers 1-10 (10x10 board).
• Valid guesses include a row followed by a column, e.g. A1, B7, J10, etc.
• You will be informed if you've hit, missed, or sunk a ship.
• Sink all 5 of the computer's ships to win!

Hint:

• When placing ships, you can also use abbreviations to make your life easier!
• Use the ship's abbreviations (see legend), and single letters for directions.
• e.g. btl a9 r or cru i6 u

Legend:

• Battleship (BTL), 4 spaces
• Carrier (CAR), 5 spaces
• Cruiser (CRU), 3 spaces
• Destroyer (DST), 2 spaces
• Submarine (SUB), 3 spaces
• A hit looks like 💥 or X (depending on Emoji support)
• A miss looks like ❌ or 0 (depending on Emoji support)
