What you get on Free Kakuro
Candidate mode
Toggle a 3×3 digit matrix in every empty cell. Mark and unmark candidates as you reason through each run — no eraser needed.
Real-time error checking
Invalid placements are highlighted immediately. Catch mistakes the moment they happen rather than discovering them at the end.
Step-by-step hints
Stuck? The hint button highlights the next provable cell and explains the logic — useful for learning without giving away the full solution.
Auto Play
Steps through all currently basic-deducible moves automatically. See the solving chain in motion before advanced technique is required.
Combination reference
Open the full combination table in another tab to look up every valid digit set for any run length and sum.
Four difficulty tiers
Easy, Medium, Hard, and Ultra Hard — each generated fresh on demand so you never replay the same puzzle twice.
Print vs. play — which is right for you?
Choose printable (KrazyDad) if you prefer the tactile experience of pencil and paper, solve away from screens, or want to work through a booklet during travel or offline. KrazyDad's PDF format is clean, well-laid-out, and prints reliably on standard paper.
Choose interactive (Free Kakuro) if you want immediate feedback as you solve, use candidate notation without managing pencil marks, or want access to hints when you get stuck. The browser app generates a fresh puzzle each time, so there is no repetition.
Many players use both: KrazyDad for paper solving sessions, Free Kakuro for quick practice and learning new techniques via the hint system.
New to Kakuro? Start here
Kakuro is a logic puzzle played on a crossword-style grid. White cells must be filled with digits 1–9 so that each horizontal and vertical run of cells sums to the clue shown in the black header cell. No digit may repeat within a single run.
If you are new to Kakuro, the beginner guide walks you through the rules and your first few moves. The combination reference lists every valid digit set for all run lengths and sums — an essential lookup tool that both print and interactive solvers use.
