or solve online (using our beta test of Penpa-Edit tools)
Theme: One, Two
Author/Opus: This is the 245th puzzle from our contributing puzzlemaster Grant Fikes.
Rules: Standard Yajilin rules, except that instead of blackening single cells, blacken in dominoes (1×2 rectangles). Clues indicate the total number of dominoes (not the total number of cells) that are shaded in the given direction.
Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 1:00, Master = 1:30, Expert = 3:00
