About Sections

Sections is a free daily logic puzzle. The grid is divided into groups of cells called sections, and your goal is to fill every cell so that each section contains the numbers 1 through its length, with no repeats. It rewards the same kind of deductive thinking as Sudoku, but the variable section lengths give every puzzle its own character.

What Makes Sections Different

Unlike Sudoku’s fixed rows, columns, and boxes, Sections is built from sections of varying lengths defined by bars that change from puzzle to puzzle. Every cell belongs to one horizontal and one vertical section at once, and the shortest section a cell belongs to sets the largest number you can place there. That single idea creates a surprising amount of depth.

A New Puzzle Every Day

A fresh Sections challenge is available every day, with grid sizes ranging from 3×3 to 9×9. Every generated puzzle is verified to have a unique solution that can be reached through logic alone, without guessing. Play a few in a row and build a daily streak.

Who’s Behind It

Sections is an independently built project made by a small team of puzzle enthusiasts who wanted a clean, fast, ad-light daily logic game. It is free to play, works on phones and desktops, and does not require an account, though creating one lets you sync progress across devices.
