Cat Sudoku - 4p Teaching, Play-through, & Roundtable Discussion by Heavy Cardboard

About Cat Sudoku, from BoardGameGeek:

Cat Sudoku is a roll-and-write sudoku game for 1 to 6 players. In the game, players take turns to roll four dice and all players simultaneously write the numbers on their sudoku puzzle papers. Similar to traditional Sudoku, players should avoid putting the same number into the same row or column in their puzzle, or they will get minus points! The game ends when players fill in all the spaces in the puzzle. The player with the highest points wins the game. Cat Sudoku comes with four different sudoku puzzles (themed with four seasons of Kyoto) at three different difficulty levels, so that you can enjoy this game with a variety of gaming groups.
