Number puzzles are puzzles where digits, totals, counts, orders or numbered clues do the heavy lifting. Some ask you to place digits, some ask you to add or multiply, and others use numbers as clues for shading, drawing, connecting or counting.
This roundup is intentionally broad and brief. It is not a rules manual for every puzzle type; it is a fast catalogue you can scan when you want to discover a new number puzzle, compare puzzle families or jump straight to a playable version on Logic Puzzles Online.

No game yetHow to choose a number puzzle
If you want pure digit placement, start with Sudoku, Futoshiki, Suguru, Binary or Latin Squares. If you enjoy arithmetic, try Kakuro, KenKen, Killer Sudoku, Calcudoku or Suko. If you prefer numbers as clues rather than entries, Nonogram, Slitherlink, Hashi, Akari, Battleship and Tents and Trees are strong choices.
Difficulty depends more on puzzle design than on the name of the puzzle. A gentle Kakuro can be easier than a hard Sudoku, and a small Slitherlink can teach number-clue logic before a larger grid becomes demanding.
