Sudoku Topology

Sudoku Topology is a collection of sudoku puzzles on 3D boards, with an editor for making your own. You solve puzzles by deduction, using classic sudoku clues alongside rules that interact with the boards’ different topologies.

3D boards and clues

Boards include spheres, cubes, cylinders, toruses, tetrahedra, dodecahedra, Möbius strips, Klein bottles and other topologies. The puzzles combine these layouts with arrow clues, thermometers, killer cages, white and black dots, odd and even clues, German whisper lines and Renban lines.

Handcrafted puzzles

The game includes more than 60 handcrafted puzzles designed to showcase logic arising from the different topologies. Every puzzle can be solved through logical deductions, without guessing or brute-forcing. An extensive series of hints is available for every puzzle, including the most difficult ones.

Create and share puzzles

A sudoku editor with a solver lets you create 3D puzzles and share them through Steam Workshop. You can also play puzzles from the Workshop that other players have rated highly.

Music and accessibility

Slow music and vibrant, minimalist visuals provide a relaxed setting for focusing on the puzzles. The game is designed to be friendly to colorblind and hearing-impaired players, can be played with a mouse alone or with a mouse and keyboard, and requires no time-sensitive or simultaneous inputs.
