Klotski (or Klocki ) is the Polish word for block. The original game was a small wooden board that could be arranged into several puzzles, where the blocks were manipulated until a master block was freed. Polish children played this game to develop basic strategy skills. The author of this program remembers playing this game as a small child. Now an accomplished programmer and artist, has recreated these puzzles as a Windows-compatible program for you to enjoy on your computer.
