Papelia Number Sum Puzzle

A number notebook made for slowing down. In Papelia, every number starts visible. Cross out or restore numbers until every row and column matches the target sum at its edge. One simple rule, thoughtful decisions, and all the time you need. If you enjoy the calm logic of Sudoku, this is a different kind of puzzle: there are no 3x3 boxes and digits do not have to be unique. Everything follows from sums and deduction. PLAY AT YOUR OWN PACE - Choose Easy, Medium or Hard whenever you like. - Explore a practically inexhaustible journey of levels. - Resume each game exactly where you left it. - No timers, lives or forced difficulty climb. A PUZZLE FOR EVERY DAY There is one daily puzzle in each difficulty. The first game you solve each day keeps your streak going and adds one hint to your shared balance. You can also return to unfinished daily puzzles. CAREFULLY BUILT PUZZLES Every new board is checked for one solution and a logical path suited to its difficulty. You begin with five hints shared across every board, alongside undo. Earn more through streaks and notebook stamps, or choose to watch an optional rewarded ad. YOUR NOTEBOOK, YOUR WAY No account is required. Your current game and preferences stay on your device. If you choose to sign in, Papelia can protect and sync your completed levels and daily puzzles, streak, hints and stamps. Puzzles and local saves work offline. Sync and optional ad rewards require an internet connection. A KAWAII CORNER FOR THINKING Papelia lives in a digitally painted gouache scene, with gentle music, paper sounds and subtle ambient motion. Adjust music, sound, vibration and motion separately, and choose from 13 languages. Cross out a number. Check the sum. Breathe. The next page is waiting.
