I got an email from Leonid Mochalov, a Russian puzzle inventor. He was drawing my attention to his web site which features many original puzzles, some of which are very unique.
The puzzle types on his page include Squarewords, a sudoku like puzzle involving words, and Express-Labyrinth, a maze-like puzzle that requires you to visit every square in a grid. The site also shows us a number of Mochalov’s block puzzles including a “Chess Cube” that you can print out and try to construct for yourself.
