About Number Fill
Number fill (fill-in) puzzles give you a list of numbers to place into a crossword-style grid. Every number fits exactly once — logical elimination finds where.
Tips
- Place the longest numbers first; they have the fewest possible slots.
- Digit crossings constrain both numbers at once — check them constantly.
- Group the list by length to speed up scanning.
FAQ
- Is there guessing involved?
- No — every puzzle is solvable by pure elimination and cross-referencing.
