Reporting a bug?

It helps a lot if you can include:

  • Which puzzle you were playing (e.g. Mini Sudoku, Killer Sudoku) and the difficulty
  • Your browser and device (e.g. Chrome on iPhone, Safari on Mac)
  • What you expected to happen, and what happened instead
  • A screenshot, if you have one handy
