If you want a game like Sudoku specifically because it uses numbers, decide whether you enjoy number placement or calculation. That distinction separates Jigsaw Sudoku from Kakuro more than their shared grid appearance does.
What number games are similar to Sudoku?
Number games like Sudoku include Killer Sudoku, Kakuro, KenKen, Calcudoku, Futoshiki, Hidato, Numbrix, Hitori, Str8ts, Suguru, Cross Sums and arithmetic-cage variants. Choose Jigsaw or Futoshiki for placement without much arithmetic, Killer or KenKen for cage calculations, and Hidato or Numbrix for consecutive-number paths.
How do number games like Sudoku compare?
| Game | Number role | Main constraint |
|---|---|---|
| Killer Sudoku | Placement and sums | Units plus cages |
| Kakuro | Crossing sums | No repeats in runs |
| KenKen | Arithmetic operations | Latin square plus cages |
| Futoshiki | Ordered placement | Inequalities |
| Hidato | Sequence | Consecutive adjacency |
| Hitori | Duplicate removal | Shade cells while preserving connectivity |
Which number games avoid arithmetic?
Jigsaw Sudoku changes region shape while keeping digits as labels. Futoshiki adds greater-than and less-than signs but requires no sums. Str8ts places consecutive sets within white-cell compartments.
These games suit players who enjoy ordering and exclusion but do not want mental calculation to dominate the solve.
Which alternatives use arithmetic?
Killer Sudoku adds sum cages to classic units. Kakuro intersects across and down runs with target sums. KenKen and Calcudoku place operations and targets inside cages on a Latin-square grid.
Arithmetic reduces candidate combinations, but uniqueness and position still matter. Strong solvers list valid sets, then use crossing constraints to orient values.
Which number puzzles build paths or sequences?
Hidato and Numbrix ask you to connect consecutive numbers through neighboring cells. Numberlink connects matching endpoints without crossing paths. Their logic concerns continuity, bottlenecks and reserved routes rather than row uniqueness.
Choose these when you enjoy seeing a path emerge. Choose Kakuro or Killer when combinations are more satisfying than connectivity.
Which is closest to classic Sudoku?
Jigsaw Sudoku is mechanically closest. Killer Sudoku is closest among arithmetic variants because it retains every classic row, column and box rule.

Want each placement to reveal part of a mystery?
Detective Sudoku is not classic Sudoku. It replaces digits and boxes with suspects, rooms and truthful spatial clues while retaining one suspect per row and column. Its real hints identify the clue behind a deduction instead of giving you the answer or solution.

What is like Sudoku but uses sums?
Killer Sudoku adds cages to the classic grid, while Kakuro builds crossing sum runs.
What is like Sudoku without 3×3 boxes?
Futoshiki and KenKen use row-column uniqueness without standard boxes.
Which number puzzle creates a path?
Hidato and Numbrix connect consecutive numbers through adjacent cells.
Do all number logic games require math?
No. Several use digits only as ordered labels or symbols.
