or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between a composite mode for line/edge drawing and a shading mode.)
Theme: Four Y Intersections
Author/Opus: This is the 24th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Divide the grid into some regions formed of edge-adjacent squares. Each cell is part of one region, and each region should contain exactly two given numbers. Each region must have an area that is strictly between those numbers (This means, for two number clues A and B with A < B, the area C fulfills A < C < B).
Answer String: Enter the number of cells in each connected group (between bold lines) in the marked rows. For the example above, this is “34,121111,4111”.
Time Standards (highlight to view): Grandmaster = 3:15, Master = 5:00, Expert = 10:00
Solution: PDF; a solution video is available here.

Nice puzzle. I think this wins the award for “most regions of a size other than the minimum or maximum suggested by the numbers”.
