How Kakuro works
Part crossword. Part number puzzle. All logic.
Fill every white square with a digit from 1 to 9. Each run must add up to its clue, and no digit can repeat within that run.
Cross the sums
Every square belongs to two runs. Use the crossing clues to narrow down the only digit that fits.
Follow the logic
Every puzzle has one solution and can be finished without guessing. The deductions grow with you.
Made for solving
Helpful when you want it. Peaceful when you do not.
Every tool is designed to keep the satisfying part in your hands. Nothing fills an answer for you.
Your puzzle stays interruption-free
No banners, pop-ups, or ad containers appear while a puzzle is open. That is a promise, not a setting.
Limited ads elsewhere. Remove them forever with a one-time purchase.
2,000+ puzzles, all included
Start with a gentle teaching ramp, then climb through six board sizes, from the 3x3 Mini to the 30x30 Colossal. Every puzzle is free.
A nudge, never a spoiler
When a move is forced, the hint explains it in plain language. When nothing is, it points at the tightest spot to look. It never writes to your board.
Smart combination help
Possible combinations and the remaining sum stay close at hand for every clue.
Pencilmarks in your colors
Sort possibilities your way with color-coded notes, automatic candidates, and strikeouts that stay struck out.
Virtually unlimited undo and redo
Try a path, step back, and move forward again. Experiment freely without losing your place.
Write answers in your own hand
On tablets, write digits straight into the cells with a stylus or a finger. It learns your handwriting, entirely on your device.
Newsprint and ink, if you prefer
A newspaper board style sets the whole puzzle in monochrome, with a charcoal evening edition for dark mode.
A fresh puzzle every day
Come back to the same daily puzzle as everyone else. A fresh logic challenge is ready every morning.
Play anywhere, even offline

Good to know
A few quick answers.
Kakuro Haven keeps the setup simple so you can spend your time on the puzzle.
Do I need to know Kakuro already?
No. A short interactive guide teaches the rules, and 25 Mini levels grow from a tiny grid into full puzzles at a comfortable pace. If you already know Kakuro, say so on first launch and start on a full board instead.
Can I play without an internet connection?
Yes. Every library puzzle, daily puzzle, setting, and saved board is stored on your device and works offline.
Are all the puzzles really free?
Yes. Every board size and every puzzle is available to free players. There are no packs, energy systems, or paid hints.
Where do ads appear?
Ads may appear on the home screen, puzzle list, completion screen, or occasionally after a completed puzzle. They never appear while a puzzle is open.
Can I remove ads?
Yes. A single one-time purchase removes every ad permanently. There is no subscription.
Is Kakuro Haven available on tablets?
Yes. Kakuro Haven supports iPhone, iPad, Android phones, and Android tablets, with a layout made for each. On tablets you can also write answers directly into the cells with a stylus or a finger.
