Just to let you know that I have added new content to Rules of Suguru. In fact I added new strategies for solving the most difficult Suguru , by the same occasion I have changed the form of this article. This is just the begining, I will add more technics soon. I will eventually offer you these kind of Suguru in Innoludic. I intend to write a book on how to solve the extreme Suguru, if I find the time and the courage to undertake this task.
I am proud to present you my latest creation : the Round Trips Puzzle (also known as Grand Tour). This puzzle is very simple, in a grid where some lines are drawny your taxk is to draw a path visiting each dot once such that at the end a closed loop linking each dot is done (see Rules of Round Trip). Each puzzle is solvable by logic, so no guess is required. This puzzle comes in a wide array of variety of difficulty and size. If you try it you woll love it, because this puzzle has the quality of a good puzzle: Simple rule and challenging to solve. The only prerequisite needed is to love to train your brain.
In order to introduce you to this puzzle I provide you 4 Round Trip puzzles with different size, but each one with an easy level of difficulty, so dont be afraid.
The last publication about the Super Sudoku of size 25X25 was popular, so in order to please you I offer you another puzzle. This is for those who likes to take their times. For the other, don't be afraid, it is the same as a regular Sudoku for the strategies used, except that it is a little bit bigger (use number from 1 to 25).
Why not solving Sudoku 3D ? This puzzle force you to think outside the box (or around the box), this is a real recreation from the standard Sudoku. I provide you two puzzles with different size and (above all) the two have irregular regions (Rules of Sudoku 3D). So the first one, a 4x4x4 cube, so use number 1 to 8.
