Explanation and Game Rules:

• The idea behind this game is to turn Sudoku into a contest between multiple players.
• The winner is, of course, the one who reveals the most numbers on the board.
• Each correct guess of a hidden square earns 10 points.
• To support a multiplayer version, a dedicated server would be required. At the moment, such a server is not available.
• To demonstrate the game concept, I developed this version where you play against the computer.
• This implementation uses JavaScript running in your browser, removing the need for a server.
• Sudoku rules: the board consists of nine 3x3 squares, each containing the numbers 1 to 9 without repeats. Additionally, each row and column of the entire board must also contain the numbers 1 to 9 without repeats.
• You can choose to start with 18 revealed squares to make the game quicker and reduce the guessing phase.
• Each turn, you roll a dice, and an arrow appears (up or down).
• The dice number and arrow define which numbers you are allowed to guess with.
• Currently we do not set a time to guess. This allow the user to hold the game, do other things, and think about the probable guess to win the game.
• Click a hidden cell, then select a guess from the allowed numbers.
• A clicked cell cannnot be changed.
• If correct, you earn points and continue playing.
• If incorrect, the turn passes to the computer.
• If the dice and arrow combination points to numbers that cannot be used, the turn is skipped and moves to the next player.
• There are four computer difficulty levels:
  • Level 1: The computer chooses a random cell and a random number from the available options.
  • Level 2: The computer keeps track of its failed guesses and avoids repeating them when selecting a square and number.
  • Level 3: The computer applies Sudoku rules to avoid mistakes but does not remember past guesses.
  • Level 4: The computer uses both Sudoku logic and memory of previous guesses to improve its choices.
• Revealed cells cannot be selected again.
• The game ends when all cells are revealed. The player with the highest score wins!
