## What is Kakuro Haven?

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, every one of them free, plus a fresh one every morning.

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

2,000+ PUZZLES, ALL FREE
Five difficulties, from a gentle teaching ramp that starts at a single 2x2 block to Expert grids up to 14x14. Nothing is locked, there are no packs to buy, and there is no limit on how many you can solve in a day.

EXACTLY ONE SOLUTION, REACHABLE BY LOGIC ALONE
Every grid is checked before it ships: one solution, no guessing, no dead ends, and no point where the only way forward is to try something and see. Grids run from 2x2 up to 14x14, so a puzzle for the bus and a puzzle for the evening are both here.

NO ADS WHILE YOU SOLVE. EVER.
While a puzzle is open the screen belongs to the puzzle. Not a banner, not an interstitial, not a "watch this to continue". Ads keep the puzzles free and appear only between puzzles and on the menus.

TOOLS THAT TEACH, NOT TOOLS THAT SOLVE
  Pencilmarks in five colors, for following 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
  Unlimited undo and redo

MADE TO BE COMFORTABLE
  Works fully offline, free. No account, no sign-up, no connection needed
  Pinch to zoom, and one tap to snap the board back
  Auto-advance to the next empty cell in the run, if you want it
  Dark mode
  Larger numbers, adjustable error checking, and a choice of tap order
  Built for iPhone and iPad, with a layout made for each
  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, no recurring anything.

Kakuro is also known as cross sums, kakkuro, or the Japanese number crossword. If you like sudoku, killer sudoku, nonograms, or the puzzle page of a newspaper, this is the one you have been missing.
