Rules of 'Sum Frame Sudoku'
Place numbers in the grid such that each row, column and 3x3 box contain the numbers 1 to 9. Numbers in the outside frame equal the sum of the first three numbers in the corresponding row or column in the given direction.
This is one of the most interesting variations of sudoku.
ReplyDeleteI enjoy solving these as they really test our logic skills.
I like them too, but I saw a little error on the first puzzle while solving it : the sum "12" concerning the region 9, line 7, should be an "11".
