Apart from the obvious negative aspect of getting addicted to them to such an extent
that you start neglecting the rest of your life, puzzles keep your brain active and sharp.
For this site, I have written some programs that generate a number of puzzles so that there are
fresh, never-been-published-before puzzles every
day that you can download and solve for free. You don't need to have an account or log-in and
you don't need to pay anything. You will need to print the puzzle out or copy it down (good luck with the
Kakuro puzzles there) but apart from that, there is no cost. You can buy books from Amazon of Uber- Ultra- and
Hyper-Gogen puzzles and Quadrata puzzles for yourself or a gift for somebody who is seriously into puzzles -
just go to the Gogen Books page or the Quadrata
Books page for detais.
Briefly, you will find Sudoku puzzles and if
you want to make it a bit harder, there are some that use a writing system for the numbers that most people are not
familiar with so looking at a 3x3 square or a row or column, a missing number will not automatically jump out at you.
p>In additon, there are two Kakuro puzzles published each day, one from the easier end of the spectrum and one from the
harder end. During the course of the week, the kakuro puzzles get larger and more involved, starting on a Monday until,
on a Sunday, you have the biggest, like so...
