Inside Kigumi

Rectangle puzzles that never need a guess

Divide the grid into rectangles: every number is the area of the piece that contains it, and every cell belongs to exactly one piece. Boards are generated on your device, endless, and always solvable by reasoning.

A five by four board in the Bloom theme on iPhone in dark mode, part way through: mauve empty cells with their numbers still waiting, and pieces laid over them — two tall lime pieces, a teal one, and a blue two-cell piece along the bottom row. Glass undo, redo and settings buttons sit above the board, and Skip and Hint capsules below it. — The board

The tutorial teaching the area rule: a three by three board with a single 6, the target rectangle outlined in white across two columns and two rows with an arrow pointing into it, and a callout reading “Try the 2 × 2 first — see what the game says.” — Learning by drawing

A late-game board in the Lagoon theme, part way through, with empty cells and colored pieces of different rectangular sizes. — Big boards

The Appearance settings in light mode show all eleven palette cards, with Bloom selected, eight premium themes locked, and Classic and Mono available, above the Kigumi Full action. — Eleven themes

The daily puzzle part way through in the Bloom theme: the same board for everyone on that date, with some pieces placed and the rest of the numbers waiting. — Daily puzzle

The picker shows Daily and Rush, one page of numbered levels, and a field to jump to another level range. — Level chooser
