Logic Puzzles

In the recent years people's interest in puzzles has been steadily growing. One of the main reasons for this phenomenon is the increasing popularity of Sudoku and Kakuro - crossword type problems, involving numbers and requiring complex analytical thinking. Even though many of you have heard about them, few are aware of the fact that there are entire tournaments for people solving such puzzles. The main ones are the World Puzzle Championship (WPC) and the World Sudoku Championship (WSC), even though there are many other smaller competitions around the World.

Below you will find a large collection of printable materials, archives of previous puzzle championships and some interactive puzzles to solve directly in your browser.
