### 5/5 — Sudoku 6 still great after two years

*2024-04-22*

Challenging, fun game, with every game winnable if you back up when stuck. Six different formats and choice of difficulty keep it interesting. Still playing and in 7th place overall. Q It must be four years by now. I think abt 12100 games won in a row now! Q 9/16/18 Amazing that it is still fun and relaxing after so long. Q By this time, I need my daily fix of It! But … now it seems to have changed and gives the player all the potential correct responses rather than making the player work to complete it! I can’t figure out how to get the old game back and will quit playing unless I can! 39,000 plus games and it’s been made so simple a kid can do it - no challenge at all!!! Q 2024 still playing, now almost 18 years and still enjoy playing every day!
It’s been about 18 years now and still a daily quiet time!
