Lazyman Sudoku is a free and fun logic game that can generate and solve Sudoku puzzles.
Lazyman Sudoku can be played two ways. You can take an existing unsolved puzzle, enter it into the playing field (use "Clear" to clear any existing locations), press "Lock" and play the game.
If you don`t have an unsolved puzzle or just don`t have the energy to find one, you can press either "Create Puzzle", or if you are more adverturesome (realy?) "Hard Puzzle".
At this point you can play manually by clicking on a square and typing in the value. Only values that don`t cause conflicts will be accepted. Press "Validate" to determine if the current board position has a solution. If you can`t find a location you can fill in, press "Hints" to display locations with single (green) or two (yellow) choices.
If you are in a hurry, press "Play Forced" to mark all the easily deduced locations, or just press "Solve" to solve the puzzle. Lazyman Sudoku is written in the Java programming language.
