Apps

We think that, once you have solved hand-crafted sudoku puzzles, you will not be satisfied with machine-generated puzzles ever again! All our apps are full of handmade sudoku puzzles by ourselves and many of the best constructors in the world, tested and hinted by Simon and Mark! NB Apps after the CTC App require the free CTC App, if using AppStore or Googleplay. Click on Steam, iOS or Android under the App you would like to purchase.
