Here are some tips for solving the puzzles:
1) Prioritize rows/columns where the sum of numbers and gaps equals the grid size (e.g., 6 3 or 3 2 3 in a 10x10 board).
2) Complete numbers adjacent to crosses or boundaries; blocks touching an edge can only extend in one direction.
3) Highlight the center blocks for single-number rows/columns. In a 10x10 grid, a "9" clue guarantees the center eight blocks, and an "8" clue guarantees the center six blocks.
4) Connect scattered blocks, using automatically filled crosses as separators to link inseparable blocks.
