Definitely not 1*

The rating is a low score ... I can only assume it's from people too good and too smug at Sudoku to not see this puzzle's place in a learner's experience. For something so small, it made me think. If I hadn't watched CTC for the past four years, I'd still be trying to solve it.

Surprisingly tricky (or maybe I’m just that bad). Fun puzzle thanks.
