(*) Warning, some older JVMs may not display the 'generating' pop-up correctly. Note also, auto-generate runs for up to 5 seconds to try and generate a new puzzle. For the larger grids, on a slow PC, this may not be long enough to find a decent puzzle, resulting in a trivial challenge. If this troubles you, please find a faster PC!
