Kakuro Haven: Daily Cross Sums

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.
