The New Sudoku Players' Forum

[ffd]

Hey,

i'm working on some (very simple) sudoku solver benchmarking software for a class and need a collection of 16x16 and 25x25 sudokus. i need txt-files or sth similar which contain as many unsolved puzzles as possible in plain text in order to download or copy and paste them in a few steps. Does anyone know where i can get something like that?

Any help appreciated! Thank you!
