Tapa (Transparent) by Prasanna Seshadri
or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)
Theme: 13
Author/Opus: This is the 33rd puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Variation of Tapa Rules. Here, the clue cells can also be blackened. This means every clue is valid for all surrounding cells (up to 9) including itself. Each clue must indicate the size of all contiguous shaded groups around it. This example image should help:
Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 4:30, Master = 8:15, Expert = 16:30

After watching Spain-Netherlands football match, I’m seeing so many ones and fives. If you prepared this one with 1-5, it would fit perfectly 🙂 You missed the score 🙂
Actually, considering that the opening game of the World Cup was on the 13th going by Indian time, I got it spot on 😉
After the first three days, the most common score-line is actually 1-3 (three matches, including the opening game), so I think 1/3 is a great World Cup theme.
Very interesting way to expand the possibilities of tapa logic. I wouldn’t have minded a less difficult one to warm up with though!
