This was really great!! I got stuck for an half an hour in box 8 before I realised how easy it was lol (I was tired hahah). The break-through was really nice!

Wow this was an extremely difficult puzzle. Took me well over 45 minutes, beautiful logic, but I feel like this is at least a 3 star puzzle. Anyway thanks for setting!

the only thing "wrong" with it is the inaccurate difficulty rating.

it seems to be a shock to many people here, but the fact is, the vast majority of sudoku solvers are NOT experts, although THIS site is definitely welcoming to experts.

so, unless the policy is to drive non-experts away from the hobby, the difficulty ratings need to take this into account.

as for THIS puzzle, there are already several steps in the early going that, while trivial to experts, are not obvious to others. and that's just to get a couple candidates onto the grid - it seems to get harder from there.

thus, the OBJECTIVE difficulty must be AT LEAST 2.
