Kakuro Haven: Daily Cross Sums

Kakuro is the number crossword puzzle game and Kakuro Haven is the calm, complete way to play it. Fill every run of squares so it adds up to the clue beside it, using the digits 1 to 9 with no digit repeated inside a run. It is a clever mix of math and logic: no guessing, just one satisfying deduction after another. 2,000+ PUZZLES, ALL FREE Six board sizes climb from a gentle 3x3 Mini to the enormous 30x30 Colossal, with Midi, Classic, Grand, and Giant in between. Every one of the 2,000+ puzzles is free. Nothing is locked, there are no packs to buy, and there is no limit on how many you can solve in a day. Each size ships in a variety of grid shapes, so a tier never feels like the same board repeated. A NEW PUZZLE EVERY MORNING The daily puzzle is the same for everyone on the same date, with no account and no connection required. The dailies are their own dedicated set and appear in no other tier, so finishing the entire library still leaves a fresh one waiting tomorrow. Keep a streak going, or just enjoy one with your coffee. EXACTLY ONE SOLUTION, REACHABLE BY LOGIC ALONE Every grid is verified before it ships: one solution, reachable by deduction alone, with no dead ends and no point where the only way forward is to try something and hope. Grids run from 3x3 up to 30x30, so a puzzle for the bus ride and a puzzle for the whole evening are both here. NEW TO KAKURO? LEARN AS YOU PLAY A tiny teaching puzzle walks you through your first solve one step at a time, and the Mini tier climbs so gently that the step up to full boards feels like a slope, not a wall. Early puzzles come with a few digits already placed to demonstrate the opening move every kakuro guide describes. When you are stuck, a hint names the next deduction and explains it, then leaves the move to you. A finished puzzle is always yours. WRITE YOUR ANSWERS, ON TABLETS On a tablet, write digits straight onto the board with a stylus or a fingertip. The app learns your handwriting on your device, so it reads you more accurately the more you play, and recognition needs no connection at all: nothing you write is ever uploaded. Prefer buttons? The keypad is always one tap away. 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 still be made, the same arithmetic a newspaper solver scribbles in the margin - Hints that explain the deduction instead of filling in the square - Virtually unlimited undo and redo MADE TO BE COMFORTABLE - Works fully offline. No account, no sign-up, no connection needed - Pinch to zoom, double-tap to zoom in and back, one tap to snap the board back to fit - Auto-advance to the next empty cell in the run, if you want it - Light and dark modes, plus a newspaper board style set in newsprint and ink - Larger numbers, adjustable error checking, and a choice of tap order - Built for phones and tablets, 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) TRACK WHAT MATTERS Your best time for every puzzle, your daily streak, your quickest solve, and your progress through every size, all kept on your device. A slower replay is reported plainly; only a genuine record gets the celebration. QUIET BY DESIGN While a puzzle is open, the screen belongs to the puzzle: no banner, no interstitial, no "watch this to continue." Ads appear only between puzzles and on the menu screens, and they are what keep every puzzle free. If you would rather never see one, a single optional purchase removes ads permanently. No subscription, no recurring anything. Kakuro is also known as cross sums, kakkuro, or the Japanese number crossword. If you enjoy sudoku, killer sudoku, nonograms, KenKen, or the puzzle page of a newspaper, this is the game you have been missing. Free on iOS and Android.
