Theme: More Big Birds

Author/Opus: This is the 36th puzzle from Bill Murphy, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). A number in a gray cell must be larger than any number in an adjacent white cell that shares an edge. (To assist solvers, this is shown like a greater than/less than shape in how the gray cells are drawn.)

Thomas Hits the GAS (highlight to view): 2:09, with SudokuPad replay file shared as a download for now (requires loading via settings menu with improvements expected before people should use this regularly).

Solution: PDF; solving video with explanation to be added later from GAS team.
