I used to play Sudoku Universe a lot. But the game is dead and has no new content 4 or more years. I had solved all (225) of the numbered levels 4 years or more ago, plus over 800 of the random levels.

But now I play genina.com on my Kindle. When I play on their Extreme level, my best time is just under 20 minutes, my 10th best time is 28 minutes. Most of my games take 30 to 40++ minutes on their toughest level.

For Sudoku Universe, I can do some Random Hard games in 7 to 8 minutes, and most Random Hard games in 10 to 15 minutes.

You got some amazing skills there mate D: Any tips? I only had a few logical rules to solve em and I believe there should be more. When I ran out of luck using all of my known rules, I simply try my luck picking a noted number and try finishing it. If it gets stuck, undo all the way back and try the other noted number XD
