Splitting Blocks

Level: Intermediate

Assign the clue blocks among the segments divided by X marks.

If cells already blocked off with X have split a line into several segments, each clue block can only be assigned to a segment its own length can fit into. A large block cannot go into a segment that is too short.

For example, if there is a segment of length 2 and a segment of length 5 and the clue is "4", the 4 can only go into the length-5 segment, so the short segment becomes all X.

By matching segments to block lengths, a particular block's place may be pinned down to just one spot, letting you apply overlap again within that segment.
