I have had a request that I produce some 4 by 4 variation puzzles. These are good sudoku for absolute beginners and younger puzzle fans. These are the only sheets I have for now, but they should keep beginners busy for a while.
All of these puzzles are quite easy, but some are easier than others. I've put loads of puzzles on each sheet, so there are not many sheets. The goal is the same as any sudoku – arrange the numbers so that each appears just once in each row, in each column, and in each (2 by 2) box. When you've done all these, go try the 6 by 6 Sudoku. Also, enjoy them!
