Also, there are two windows in the upper left (blue) and lower right (red) of the grid. If a cell is used by the loop in one window, then the cell in the same position in the other window is not used by the loop.

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. Separate each row’s entry with a comma. For the example, this would be “11,12”.

Time Standards (highlight to view): Grandmaster = 1:45, Master = 2:30, Expert = 5:00

    I always like windows variations.
    However, this time the explanation is confusing. The text only states that the loop cannot go through the same tile in both windows. That permits tiles being unused in both windows. But the image suggest a tighter restriction: exactly one tile has to be used in either image. Which is also closer to how windows work in other variations.
    Either the text or the image is wrong.
