Macdoku for Free


Via Digg.com I found Macdoku which is a free and open source Sudoku puzzle generator, solver, and assistant.

With Macdoku, you can easily manage the possibilities available to each square. The three main possibility constraints are updated live as you type, and other possibilities can be managed in elimination mode. Highlighting of squares with one remaining possibility can be toggled on and off.

Pressing TAB will now automatically fill in all such solved squares. It uses qqwing to generate new puzzles with various levels of difficulty, and Sudoku-solver-in-c as its solving engine. Happy Puzzling!

Trigon Puzzles


Last week I received an e-mail about a Sudoku look-a-like, called Trigon Puzzles.

Trigon is a set of triangular domino’s is put together in various shapes and sizes. There is a number on each side of the triangle and a central number which is the sum of the side numbers. Where two sides meet, the number is the same.

To save writing the number twice a gap is left in the sides. The problem is that you are only presented with the central number and you have to use logic to determine the side numbers. Happy Puzzling!
