I bought the Sudoku "The Board Game" for my son for Christmas and I am confused about the rules. It is a multiplayer game for 1 to 4 players. The main rule is the same as regular Sudoku, but there is another rule called "Challenging" which says, "On your turn you may challenge a number that has been previously placed. Simply erase the number and take your turn by placing another number in that location or anywhere else on the board. DO NOT look at the solution to the puzzle until the end of the game."
Well, my 8 year old figured out it was a good idea to challenge every single move! So at the beginning of his turn, he erases one of my numbers and writes down one of his. You can see how it turns into an endless loop if we challenge every single turn! I just don't get it. Help!
The rule for winning is "Players get a point for every correct number/location made in their color marker. The player with the most points wins."
