Last month I already wrote about Giant Sudoku’s and suggested them to make the Sudoku’s not only printable format but available online.

Well at Giant Sudoku’s they have been very active and created some interactive versions of their Sudoku’s (4×4 to 36×36 and 9×9 Wordoku’s). You can not solve the puzzles online but the only application you’ll need is Microsoft Excel.

All other formats of Giant Sudoku’s are still online (like 16×16, 25×25, 36×36, 49×49, 64×64, 81×81 and 100×100, so Sudoku’s with grids from 256 to 10000 cells). Happy Puzzling!

If normal Sudoku’s are boring for you than you must visit this French website with Giant Sudoku’s. The site is in French but that shouldn’t be a problem as the numbers in French are the same as in English.

You will find Giant Sudoku’s in several sizes : 16×16, 25×25, 36×36, 49×49, 64×64, 81×81 and 100×100, so Sudoku’s with grids from 256 to 10000 cells. A new set of grids is proposed every week.

As far as I could see it was not possible to play online or easy to print the Sudoku’s, hopefully that will change soon.

LCM Sudoku is another Sudoku variant, and this one is based upon the arithmetic and number theory, the least common multiple (LCM).

Rules of LCM Sudoku are like the standard Sudoku, this Sudoku has three basic rules: 1. Each column, each row and each box (3×3 sub grid) must have the numbers 1 through 9. 2. No column, row or box can have two squares with the same number. 3. The puzzle can be solved by finding the values of the 9 given variables in the squares of the 9×9 grid.

Stars & Stripes Sudoku, is another Sudoku variant by USA Sudoku.

Each 12 x 12 grid has the familiar 1 – 9′s, but also has three stars in each row, box and column. Instead of using letters A, B,and C, the puzzle uses three stars in the form of an asterisk (*). The difference is the 3 stars (*) are the “same”. Each row, column, and 4×3 box will contain three stars in a finished puzzle.

The 100 puzzles in this book range from easy warm-ups to ruthlessly difficult challenges and are sure to [Read More...]
