Engaging yet challenging opening, and then after placing a few rivers cells things really start to flow like…water. Loved it!

Updated rules to clarify wording. Changed links to point to versions with this new wording.

Really enjoyed this one. Loved figuring out the river and the look of the grid.
Start is a little tricky so it took me some time to get the river going but after that it just kept flowing ;)

Cool puzzle with a nice take on the river rules. Worked very nicely and smoothly, would recommend this one for solving, although a bit of focus is required!

What a wonderful puzzle with plenty of engaging (yet challenging) moments, really had to wrap my mind fully around the rule set to finally understand what's going on in the mid solve. I particularly enjoyed the bits in c456 and final disambiguation of the river path :)

Clarification to the rules: added 'non-branching' to the river building instructions both on this page and on the puzzles themselves.
