Kakuro: Combo Helper Offline

Kakuro, also known as cross sums, is a number crossword. Fill every white cell with a digit from 1 to 9 so that each run adds up to its clue, and never use the same digit twice in one run. The clues sit in the dark cells: the number above the diagonal belongs to the run on its right, the number below it to the run underneath. This Kakuro comes with a combination helper, big cells and 10,000 puzzles, each with exactly one solution that logic alone will find. Play offline, with no account to create. THE COMBINATION HELPER Tap a cell and the combination helper shows both of its runs, across and down, each with its sum, its number of cells and the digit combinations that can make it. For example, 23 in 3 cells can only be 6, 8 and 9. As you write digits, only the combinations that contain them stay, and the digits you have used are dimmed. Prefer to work it out on your own? Switch the helper off in Settings. ONE SOLUTION, NO GUESSING A solver has checked all 10,000 puzzles: each one has exactly one solution and can be finished by logic, without a single guess. Difficulty is graded by the solving techniques a puzzle needs, so a higher level asks for deeper reasoning, not more guesswork. HINTS THAT TELL YOU WHY Stuck? A hint fills in one cell that can be worked out right now and tells you why, naming the run and the reason. A hint can read: "Across: 4 in 2 → 1·3. Down: 3 in 2 → 1·2. So this cell is 1." Follow the reasoning once and you can use it yourself in the next puzzle. 10,000 PUZZLES, YOUR CHOICE OF SIZE • Five grid sizes: 6×6, 8×8, 10×10, 12×12 and 15×15 • Four difficulties: Easy, Medium, Hard and Expert, chosen separately from the size • 500 puzzles for every size and difficulty • Random puzzle: a brand-new puzzle made on your phone in a moment THE DAILY PUZZLE AND ITS CALENDAR Each day brings a new 10×10 daily puzzle: easy on Monday, a little harder every day, Expert on Sunday.
