Frame Sudoku - 200 Normal Puzzles 9x9 (Volume 3)
Sendes innen 5-16 virkedager
Sudoku (also known as "Number Place") is a placement puzzle.
The puzzle is most frequently a 9 x 9 grid made up of 3 x 3 subgrids (called "regions").
Some cells already contain numbers, known as "givens".
The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 9 exactly once.
Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.

Frame Sudoku (also known "Outside Sum Sudoku") consists of an empty grid. Numbers in the outside frame equal the sum of the first three numbers in the corresponding row or column in the given direction.
