Difficulty levels of the practise sudokus
We received some feedback on the difficulty levels of the practise sudokus; players found some of them to be very tough nuts to crack.
We can reassure you that indeed some of them are actually harder than the contest puzzles, so don’t be scared off by the difficulty of the practise sudokus! In our opinion it is better to practise with a harder puzzle than with an easier one. The easier ones are in the Instruction Booklet.
