Sudoku Snow World
Now here is a free online Sudoku game that has a twist. It has the Classic Sudoku and another variant that is less hard. Firstly there are two levels that you have to contend with. There is the Easy and Hard level. In each of these you will find two puzzles. The first is the Classic; the classic has a 9X9 grid that is divided into nine 3X3 grids. Each of these grids must have the numbers 1 to 9 without any repetitions. Similarly, the larger grid must have the numbers 1 to9 in the rows and columns without any number being repeated. The second is a smaller puzzle 3X3 puzzle in which you have to put the numbers 1 to 3 without any repetitions in the rows and columns. For anybody who is starting to understand the smaller grid in the Classic Sudoku, then this is a god training ground. The levels start with 2 numbers, then 1 number etc. it is just supposed to show you how you should fill the 3X3 grid although it does not use the numbers 1 to 9 but uses 1 to 3.; it helps you understand the non-repetition of numbers in the columns and rows of the larger 9X9 grid in the Classic Sudoku. After a few levels it goes into being a 4X4 grid and so on. When you go into the Classic part of the game, you will follow the normal Sudoku rules; the number 1 to 9 must not be repeated in any of the 3X3 grids and in any of the columns and rows of the larger 9X9 grid. This is a great game for mental exercise. Rather than do the crossword puzzle, you had better solve the Sudoku puzzle; it will be an experience that will have you asking for more.
