I have invented a puzzle about the start of the year that I believe is new. But is it really? I call it Begriddled.
It uses a grid of characters that you join according to a sequence (either given or to be partially or fully deduced by the solver) to reveal a hidden design (generally text or a picture).
Here's an example I've used in showing how it works:
The rules are:
Rule 0: Dots are dots. You do nothing with them except pencil them in. They are the only character that does NOT obey Rule 1.
Rule 1: Join all pairs of horizontally and vertically adjacent characters that are the same.
Rule 2: Join all pairs of horizontally, vertically, and diagonally adjacent characters that appear next to each other in the circular sequence.
The "logic" version is exactly the same except you must deduce part or the whole of the sequence from additional rules.
Here's an example of the logic version which while clearly not so simple is intentionally not so hard either.
Is anyone aware of anything like this already out there (except, of course, for my own examples which are easy to find by search for the name)?
The result looks best if you use thick bold lines right across the grid of characters, for example drawing a single thick line right across the stack of three 5's in the above.
