Hexle

Hexle is a number-guessing puzzle game based on Sudoku. You fill grids while following rules that restrict where each number can go.

Puzzle rules

Each number can appear only once in each line and each 4x4 square. Binary restrictions within each square also limit which numbers can be placed on each tile. The game’s introduction teaches you the rules before you tackle generated puzzles at various difficulty levels.

Daily and weekly puzzles

You can return for daily challenges or solve weekly 16x16 megaboards. Completing puzzle grids unlocks color palettes that change the game’s appearance; light and dark palettes are available from the start.

Save your puzzles

You can stop playing at any time and continue later. Each difficulty has one save slot, which you can continue or reset at any time.
