That reminds me of Marilyn's Numbrix puzzles in the Sunday Parade newspaper supplement. For the past two years or so, all of hers have clues in, and only in, the odd-numbered squares around the perimeter.

The concept is not that difficult, the Numbrix & Slitherlink are exact cover problems which can be programmed then by choosing the approriate solution grids, generating these grids will be very easy .....
