Hexologic

In Hexologic, you solve logic puzzles on hexagonal grids by placing dots in each cell. The numbers shown beside the grid give the required totals for lines of cells.

Lines overlap in three directions, so each placement affects multiple sums. Later puzzles introduce variations such as linked cells and comparison clues, adding constraints to work through.

The campaign spans six worlds and more than 90 levels, with new rules introduced as you progress. Difficulty modes vary the assistance available, and reviews describe bonus and endless puzzles for some mechanics.

Players often describe Hexologic as a relaxing, approachable logic game, praising its mellow music and gradual introduction of puzzle mechanics. Some enjoy the increasing challenge, while others find much of the game easy or feel that certain puzzles encourage trial and error. A recurring criticism is that the campaign is short, and some players dislike the reduced feedback or limited note-taking in harder modes.
