Kumi: Number Logic Puzzle

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
