The Password Game is a web browser game that has you create an increasingly complex password that must meet all the rules that are displayed. The rules start out pretty standard but get increasingly complicated. Rule 16 displays a chessboard with pieces and asks you to include the best move in algebraic notation in your password. This can be hard to solve, especially if you don't know much about chess or how to write algebraic notation. Luckily, this can be solved pretty easily. This wikiHow article teaches you how to solve Rule 16 in The Password Game.

Beat Rule 16

The chess pieces in Rule 16 are generated at random. You will need to determine the most optimal move and include the algebraic notation in your password. If you're not good at Chess, you can use a website like nextchessmove.com to figure out the next move in algebraic notation.

1. Include the next optimal move in algebraic notation in your password. Since the chessboard is randomly generated for each game, there is not one correct answer.

   • To solve this puzzle, you will need to know how to play chess and how to read and write algebraic notation.
   • If you are not skilled at chess, there are ways you can cheat to find the answer.

Algebraic Notation Explained

Download Article

1. 1
   Chess piece letters. In algebraic notation, each chess piece (except for pawns) is indicated with a capital letter. The first letter in algebraic notation indicates which piece is being moved. If no capital letter is in front of the move, this indicates the piece being moved is a pawn. The letters for the chess pieces are as follows:

   • "K" = King
   • "Q" = Queen
   • "N" = Knight
   • "B" = Bishop
   • "R" = Rook
   • No letter = Pawn
2. 2
   Board positions. This indicates where the piece moves to. In chess, the vertical columns of the board are indicated by the letters A - H with the furthest column on the left being the A column, and the furthest column on the right being the H column. The horizontal rows of the chessboard are numbered 1 - 8 with the row that is closest to the player being the 1 row, and the row that is furthest from the player being the 8 row. If a piece moves to e4, this indicates it is moving to the space that is in the 4th row in the "e" column.
3. 3
   Special moves. In addition to the pieces and where they can move to, there are also notations for what a piece does in that space. They are as follows:

   • "x" = piece captured: If a piece captures another piece during a move, this is indicated by placing an "x" after the piece letter and before the square that it moves to.
   • "+" = check: If the move puts the other player in check (meaning their king can be captured), this will be indicated by placing a plus (+) sign after the notation.
   • "++" = checkmate: A checkmate is the winning move in chess. It indicates the other player's King is in a position to be captured, and they have no moves to escape. If a move puts the other player in checkmate, it is indicated with a double-plus (++) at the end of the notation.
   • "0-0" = kingside casting: Castling is a special move in which the King and the Rook move simultaneously and switch sides. It can only be done if the king and rook have not moved yet, the king is not in check and doesn't pass through a check, and there are no pieces in between the king and rook. If can king castles with the rook on the kingside (right side), this is indicated with a "0-0".
   • "0-0-0" - queenside casting: If a king castles with the rook on the queenside (left side), it is indicated with a "0-0-0".
4. 4
   Examples of algebraic notation. The following are some examples of algebraic chess notation with explanations:

   • "e4"—This is a pawn moving to the "e4" square. Since there is no capital letter in front of the space, we can assume it is a pawn that is moving.
   • "Nc3"—This is the knight moving to the c3 square. The capital "N" indicates it is a knight moving.
   • "Bxf4"—This indicates the bishop moves to the f4 square and captured a piece on that square. The "x" placed between the piece and square notations indicates it is capturing a piece.
   • "Qxa4+"—This indicates the queen is moving to the a4 square, capturing a piece and putting the other player in check. The plus at the end indicates the other player is now in check. The "x" indicates the queen is capturing a piece on the "a4" square.
