Mix Sudoku Light
Here is a game where you mix many forms of Sudoku. The puzzle contains the regular 9X9 grid but the game follow different forms. The first is the classic Sudoku in which you get to fill 3X3 grid with the numbers 1 to 9 without repeating any often and making sure that they are not repeated in the 9X9 column and row grid. Then there is the diagonal game in which you fill the smaller grids and columns and rows with the number 1 to 9 without repeating them, but a new dimension is added; the numbers must not repeat in the diagonal axes of the bigger grid. The irregular Sudoku must also be filled as the classic, but the irregular shapes drawn using thick lines must also have the numbers 1 to 9 without them being repeated. The odd and even Sudoku has the clues that are found in the classic game, but it has dark areas, which have a single number, and they have to be filled with even or odd numbers; if the dark area has a number 4, then the only numbers that can fall in it are 2, 6 or 8. Then there is the Chain Sudoku in which the columns and rows should not repeat, and the linked chains too. The grids in these games can be as small as 5X5 instead of 9X9. The Multi Sudoku is a mean form of Sudoku which has two classic Sudoku grids overlapping one another. Given all these games, you will spend a lot of time playing this particular variant. Once you have completed one, move on to the next so that you have a change of pace and challenge. This is a game that will truly test how adaptable you are when it comes to dealing with different forms of the same puzzle at almost the same time.
