About this game

Kakuro is the number crossword. Fill every run of white squares so it adds up to its clue, and never repeat a digit inside a run. Pure logic: no guessing, basic
arithmetic, and no timer breathing down your neck.

★ 2,000+ PUZZLES, ALL FREE
Six board sizes, from a gentle 3x3 Mini to the 30x30 Colossal. Nothing is locked behind a paywall, there are no
puzzle packs to buy, and there is no daily limit on how many you can solve.

★ A NEW PUZZLE EVERY MORNING
The daily puzzle is the same for everyone on the same date, with no account and no connection needed. Build a streak. The dailies are their own puzzles and appear in no other tier, so finishing the entire library still leaves one
waiting for you tomorrow.

★ WRITE ANSWERS IN YOUR OWN HAND, ON TABLETS
Write digits straight into the cells with a stylus or a finger. It is the closest thing to pen and paper. The app learns your handwriting. Everything stays on your tablet: nothing is uploaded, nothing is downloaded, and recognition needs no connection at all.

★ EXACTLY ONE SOLUTION, REACHABLE BY LOGIC ALONE
Every grid is checked before it ships: one solution, no guessing, no dead ends,
and never a point where the only way on is to try something and see. Grids run
from 3x3 to 30x30, so there is a puzzle for the bus and a puzzle for the
evening.

★ NEVER AN AD WHILE YOU SOLVE
While a puzzle is open, the screen belongs to the puzzle. Not a banner, not an
interstitial, not a "watch this video to continue". Ads keep the puzzles free
and appear only between puzzles and on the menus.

★ TOOLS THAT TEACH, NOT TOOLS THAT SOLVE FOR YOU
- Pencilmarks in five colors, so you can follow more than one line of reasoning on the same grid at once
- A dedicated notes mode, so inking an answer never wipes out your pencilmarks
- Auto-fill candidates, which never puts back a digit you ruled out yourself
- A combination row showing every way the current clue can be made
- Hints that explain the deduction and then leave the move to you
- Virtually unlimited undo and redo

★ COMFORTABLE TO USE
- Fully offline, free. No account, no sign-up, no connection required
- Pinch to zoom, double-tap to zoom in and back, and one tap to snap the board back
- Auto-advance to the next empty cell in the run, if you want it
- Light and dark modes
- A newspaper board style, set in newsprint and ink
- Larger numbers, adjustable error checking, and a choice of tap order
- Phone and tablet, with a layout made for each
- In 16 languages: English (US and UK), Spanish (Spain and Mexico), French (France and Canada), German, Italian, Dutch, Portuguese, Turkish, Hindi, Japanese, Korean, and Chinese (Simplified and Traditional)
- Your best time for every puzzle, kept on your device

★ ONE PURCHASE, IF YOU CHOOSE. NEVER A SUBSCRIPTION.
The free app is the whole game. If you would rather see no ads at all, a single
optional purchase removes them permanently. No subscription, nothing recurring.
