Normal sudoku rules apply.
Chess pieces have the following rules:
Pawn: The Pawn has a lower digit than any of its surrounding cells.
Bishop: Digits can't repeat on a diagonal that passes through a cell with a Bishop.
Knight: There are exactly two cells a Knight's move away from this cell that have the same digit as the Knight.
Rook: The Rook is positioned between the 1 and 9 in its row and column. Digits between the 1 and 9 in its row have the same sum as the digits between the 1 and 9 in its column.
King: With the surrounding cells of the King, four dominoes (these are two orthogonally connected cells) can be created. For each domino, the sum of its digits must be equal to the digit of the King.
Queen: From the Queen's cell, straight arrows of varying length can be drawn in all eight directions. The digits on each of these arrows sum to the digit of the Queen.
