This is a scrabble AI (Artificial Intelligence) I decided to write as a quick 1 day project (though I went back later and reoptimized a bit more) in C that takes any board configuration and tile set and finds the best possible word worth the most points during that turn.

It utilizes a brute force AI, and a Digital Search Tree for the Dictionary. The dictionary can be any plain text file with words separated by spaces named dict.txt. Press F2 for my example board.

• At any time
  • Arrow keys: Move around the board, the tile rack can be reached by moving past the bottom row.
  • Enter: Run the AI to find the best word
  • F1: Saves the current board and rack to ScrabbleBoard.sve
  • F2: Loads the current board and rack from ScrabbleBoard.sve
  • Space: Add a blank tile to the rack. Using a blank makes the AI take exponentially longer. 2 spaces can take up to around 30 seconds (on my current computer) as there are an exponential number of more possibilities to search through.
• When on the board
  • A-Z: Place a lettered tile
  • Delete or BackSpace: Remove a tile
• When on tile rack
  • A-Z: Add a tile to the rack. A maximum of 7 tiles are allowed.
  • Delete or BackSpace: Remove the last tile

• Scrabble.exe: Loads the normal dict.txt plain text dictionary
• ScrabbleDBT.exe: Loads the dict.dbt dictionary file, which is in a custom digital binary tree format. This has a smaller dictionary file and is much quicker to load.
