An enjoyable medium. I marveled at your self-inflicted pains in going through the central horizontal chute, in the course of which you so artfully avoided seeing the 36 pair straddling the 8 in the lower row of block 5, which immediately gives you the 4s. Doing it this way, I got a 9 so quickly in block 9 that I actually did not realise there was no given 9 in the grid. In the end, I needed a little bit over 10 minutes to go through the puzzle.
