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: The most popular puzzle of TVC XI
Author/Opus: This is the 153rd puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Variation of Tapa. Each clue cell contains two sets of numbers. Black numbers are regular Tapa clues for immediately neighboring cells. Gray numbers supply clues for secondary neighbors that are separated by one cell from the clue cell. (It may help to refer to the figure below that shows the two rings of cells affected by black numbers and gray numbers.)
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 = 5:00, Master = 8:30, Expert = 17:00
Solution: Solution: PDF; a solution video is available here.

For the gray clues, does order matter? In other words, for the 1123 clue, can it be shaded 1213? I’m pretty sure that “order” doesn’t come into play in regular TAPA because clues (except for 1111) max out at three clues, and therefore wraparound makes order moot. Thank you!
Order doesn’t matter and both shadings you mention would be allowed.
