Sudoku Voyage: Classic Sudoku

Sudoku Voyage is classic sudoku — the 9×9 number logic puzzle — turned into a journey around the world.

Solve a puzzle, clear a stage, and move to the next city on your route. Lisbon, Marrakesh, Istanbul, Kyoto, Busan and Sydney wait along the way: 120 stages in all, with landmark stages that leave a postcard in your album.
