cage shape
This isn't an idea for a pattern, but it could turn into one.

I don't believe I've ever seen a T-shaped 4-cell cage; like the Tetris piece. Any reason why?

Ah, really good point! I immediately realized that this is because of my cage
creation method: it starts at a point, then makes a random step, etc., until
the required size is reached.

I'll modify the algorithm soon so it creates more varied cages. I can't believe I didn't
see this myself at some point, thanks much

You're welcome! A cross-shaped cage would be interesting too. Like: a2b1b2b3c2

I 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:

a1
a2b1b2b3c2
c1d1
d2e1e2e3f2
f1
a3a4
c3d3 (or: c3c4, d3d4) (or: c3c4d3d4) (or something like: c3c4d3, d4)
c4d4 (different ones may be useful to modulate difficulty)
f3f4
a5b4b5b6c5
d5e4e5e6f5
a6
c6d6
f6

Re: cage shape
There is a cross shaped cage in one of the book puzzles......rating is: very difficult.....have tried to solve it once but had no success.....it's in the "black coloured book"..........Ken

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 will
no longer "feel familiar" )

Here are two samples:

Re: cage shape
Have you ever thought about using a mandelbrot equation to generate cage shapes?

Here's another one, not easy (!)

Not really. How would that work?

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.
