Author/Opus: This is the 2nd puzzle from guest contributor Joseph Howard.
Rules: Standard Cross the Streams rules. Also, some sets of row/column clues have comparisons made to the left-most or upper-most ? clue. The value used for a ? clue must also be used for the remaining comparisons in that row/column (e.g., if ?, ?+2 the values could be 1, 3 or 2, 4 or 3, 5). ?= means a later clue has the same value as the first ?.
Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.
Time Standards (highlight to view): Grandmaster = 7:30, Master = 12:00, Expert = 24:00.
