Logic Masters Deutschland e.V.

Small Disclaimer: I put this puzzle in as 2 star difficulty but it is probably somewhere inbetween 2 and 3. If you know "the secrets of Yin Yang" (as they are called on CTC) it should be doable.

Rules:
- standard sudoku rules: digits 1-9 in each row, column, box
- standard yin yang rules: shade some cells in the grid such that all shaded and all unshaded cells are orthogonally connected and no 2x2 area is fully shaded or unshaded
- candles illuminate the grid and have to be unshaded. Additionally, a digit on a candle is equal to the number of consecutive unshaded cells (including itself) the candle sees in its row and column
