Very fun and suitable for someone familiar with common Sudoku Variants but new to Akari. I found the Akari very approachable and learned some techniques for it, but also had some excellent challenging Sudoku logic.

The Bulb logic was really nice and flowed well. The Sudoku part was the right amount of challenging! Great Puzzle!
