I've been doing the Guardian Saturday hard sudokus for a long time. I print off a load if I'm travelling as I like the standard of difficulty (occasionally easy but generally a good standard of difficulty for me)
Anyway in lockdown I've had a bit of time to do more and notice hard had been replaced by expert.
Now maybe I'm just getting much better at them, or expert us just no where near as hard as the old hard ones.
Anyone else noticed?
