Any reason why? Ah, really good point! I immediately realized that this is because of my cagecreation method: it starts at a point, then makes a random step, etc., untilthe required size is reached.I'll modify the algorithm soon so it creates more varied cages. I can't believe I didn'tsee this myself at some point, thanks much Patrick

Like: a2b1b2b3c2I can't think of any others off the top of my head that are more branched that would bring anything extra to a puzzle.Now that I've thought about it a little, a cross-shaped cage would lend itself to a nicely symmetric pattern puzzle. I think this is the type of code you use:a1a2b1b2b3c2c1d1d2e1e2e3f2f1a3a4c3d3 (or: c3c4, d3d4) (or: c3c4d3d4) (or something like: c3c4d3, d4)c4d4 (different ones may be useful to modulate difficulty)f3f4a5b4b5b6c5d5e4e5e6f5a6c6d6f6

Any reason why?Ok, I've fixed up the cage generation algorithm.Starting May there should be more variety in the cages (I'm sure that certain puzzles willno longer "feel familiar" )Here are two samples:

 Author: jotempe  [ Fri Apr 27, 2012 11:15 am ] Post subject: Re: cage shape The last one was relatively easy, solved it by pure logic (no guessing) in a few minutes - subjecively I'd put it a 5x5 medium category.
