Ready.
Quick setup
All generated equations form one continuous connected network, like the reference cross-puzzle worksheets. Difficulty changes clue density and reasoning depth, not just arithmetic size. The same seed reproduces the same puzzle.

Advanced generation controls
Hard and Challenge emphasize shared-number intersections, longer forced deduction chains, fewer immediate starting moves, and verified propagation to a forced solution path. Print fitting uses the actual trimmed grid and paper dimensions to prevent clipping.
