A new puzzle every day, the same for everyone. Stuck? Kareli shows where to look, names the technique and only then gives the answer. No ads. Kareli is a calm sudoku that teaches you how to solve, not just what to write. HINTS THAT TEACH When you get stuck, a hint comes in three steps. First Kareli shows where to look. Then it names the technique and explains it. Only then, if you want, it shows the answer. Advanced steps are drawn on the board: the cells that matter are highlighted and the candidates you can remove are crossed out. A NEW PUZZLE EVERY DAY Everyone gets the same daily puzzle. The week starts easy on Monday and reaches expert level on Sunday. Keep your streak going and share your result with a spoiler-free card that never gives away the solution. COPY A PUZZLE FROM YOUR BOOK Solving a sudoku book? Take a photo of the puzzle and Kareli reads the digits on your phone, or type it in. Kareli checks that the puzzle has exactly one solution, tells you how hard it is, and helps you with hints when you get stuck. PUZZLES THAT NEED NO GUESSING Every puzzle is generated on your device and can be solved by logic alone. Difficulty comes from the hardest technique you need: Easy, Medium, Hard and Expert, from hidden singles to X-Wing and Y-Wing. YOUR TECHNIQUE NOTEBOOK Each technique you meet in a hint is collected in your notebook with a short explanation, so you can see how far you have come. MADE TO BE COMFORTABLE • Large digits mode for easier reading • Light and dark themes • Pencil notes, auto-fill candidates and unlimited undo • Instant mistake checking, or turn it off and solve like on paper • English and Turkish NO ADS, NO ACCOUNT Kareli is free, has no ads and needs no account. Your progress stays on your device and it works offline. Photos of puzzles are read on your device and never uploaded.
