I'd love to see some hints on how to solve the dotted snakes. I managed to guess possible solutions to the left two puzzles by now, but I find snakes hard enough to solve without the added interactions between the grids. General snake solving advice would also be appreciated -- I often struggle on those croco snakes that some people throw out in a couple of minutes…

Also, thanks a lot for the test. I loved the concept of the test, and the puzzles that I solved. The puzzles were a bit on the hard side for me, so that guessing instead of staring in places would probably have been a good idea. In the end, I was surprised by how well I placed, since it didn't seem like a good performance. I sunk a lot of time into the Easy as ABC that turned out to be broken in the very end, and never felt fast.

The intended order of solving was starting from bottom right and going clockwise: in that case every single puzzle could be solved uniquely.

Thanks, I got through now. It turns out the two solved grids were ok. I realized some new things about dotted snakes in the process (particularly how they're close to "star battle" in some ways), though I didn't actually manage to prove uniqueness.
