500 Hex Puzzles

I just saw this and I'm ecstatic. Thank you!

If you do print it, let me know how it goes. I don't have a printer so I wasn't able to test how it looks (especially in black and white..)

Very nice ! This comment spoils 198 a bit.

I just done puzzle 198 and I'm curious about it. Usually, we know we are connected because there are two ways which not overlap each other. Here it seems to lack such pattern and it looks like the best way to know if we're connected is to test a lot of blockers. But it that really so ? Did someone find a good way to be 100% sure we're connected without testing ?

As you say, many problems can be solved by reduction to two or three non-overlapping connections, or by some "standard" ladder techniques (or both). In my notes the ones that can't be solved in this manner I referred to as "messy." There are quite a few such "messy" problems in the collection, although most are in the higher difficulty levels. These are some of the hardest problems because you have to read out possible lines mentally to confirm that they all work.

Cool
