Kropki 3D Sudoku is a mobile puzzle game that combines traditional Sudoku rules with Kropki dot clues on a three-dimensional cube, challenging players to fill each face with digits 1–9.
What is Kropki 3D Sudoku?
Kropki 3D Sudoku is a mobile puzzle game for iOS where players solve Sudoku puzzles on a 3D cube. Each of the six faces must contain digits 1–9 exactly once, with Kropki clues linking adjacent cells across edges.
