Normal 9x9 Sudoku: Place the digits 1-9 exactly once in every row, column, and 3x3 box.
Anti-King: Cells that are touching (share a border or corner) cannot contain the same digit as each other. It is called "King" because that is how a King moves in chess.
German Whispers Lines: Green lines in the grid are German Whispers lines. Adjacent digits along the line must have a difference of at least 5.
Find the following words in the puzzle: Puzzle, Killer, Thermo, Kropki, Renban, Arrow, Clone, Grid, Cell, Even, Row, Box, Odd. The remaining cells may contain only digits from the Fibonacci set (1, 2, 3, 5, 8).
