I'm looking to do some challenging puzzles. I'm looking for an app or website or somewhere where I can do challenging puzzles for free. I would use chess.com, but you have to pay to do a lot of puzzles. I would use chesstempo but I'm at a point where even when I turn the setting to hard I can solve the puzzle in 20-45 seconds. And I would use lichess, but most of the time when I do puzzles it's on my phone and for whatever reason lichess puzzles are very easy whenever you do them on mobile. I don't want to pay for anything and there's probably a website that has hard puzzles that I'm looking for but I am yet to find it. Can anyone help me out here?
