Kumi: Number Logic Puzzle

About

Kumi is a calm number puzzle: split the grid into groups of neighboring cells whose digits add up to the total. Simple to learn, deeply satisfying to master. It is a logic puzzle, not a math test: small sums, no timer, and exactly one solution that you find by reasoning, never by guessing. HOW IT WORKS • A clue like ▢▢ = 10 says it all: groups of 2 cells that add up to 10 • The cells of a group touch by a side, never just a corner • Every number puzzle has exactly one solution A DAILY PUZZLE AND A CALENDAR • A new daily puzzle each morning, the same for everyone • A calendar to replay the days you missed • Solve every puzzle of a month to win its trophy • An optional daily reminder, at the time you choose A PATH TO FOLLOW • Four worlds: Duo, Trio, Quartet and Expert • 17 levels, each one a stage of 10 puzzles, then endless puzzles to keep playing • Each solved puzzle adds a piece to the picture of its world • A star for every puzzle solved without a hint AT YOUR OWN PACE • No timer, no lives, no pressure • Classic mode: no help, the grid is checked at the end • Guided mode: a group lights up as soon as its sum is right • Hints that explain the reasoning before showing the answer • Undo as often as you like DESIGNED TO BE EASY TO READ A number puzzle made for comfortable reading: • Big numbers and high-contrast colors • Larger text option, light or dark theme • Draw a group by sliding your finger, or tap the cells one by one RESPECTFUL • Never an ad during a puzzle • No account needed • Your progress stays on your device • Every puzzle works offline WHAT IS INCLUDED Every level, the daily puzzle and the pictures are included, with no time limit.
