Divine Puzzles and Games brings you 400 new puzzles for hours of playing fun. Elemental Sudoku includes four sections with increasing difficulty levels to fit your individual skill. No math is required. Numerals are used simply as one of nine unique, easy to remember puzzle elements. Fill the grid by using each element only once per every row and column. The solution is further achieved by considering that the nine smaller 3x3 grids may contain only one each of the unique elements.
