Floody Hekc

It's Starq Jr.! and I collaborated on this puzzle, so be sure to blame him if you don't like it! Huge thanks to him, it's been a blast working on my first collaboration.

Floods are sadly becoming more frequent and more severe, as a result of the changes in our climate. This sudoku calls attention to the utter devastation that flooding can cause and so, if you enjoy the puzzle, perhaps consider donating to a flood relief project in response. Thank you.


Normal sudoku rules apply.
Digits on a white dot are consecutive.
Connect the two river cells with a non-branching, one cell wide river, that doesn't touch itself orthogonally or pass through mountain cells.
Digits in river cells must equal the number of other cells seen orthogonally from that cell, up to but not including mountain and river cells.
The river floods, and the flooded river contains all river cells and all non-mountain cells orthogonally adjacent to a river cell.
Any white dot touching this flooded river is broken by the floodwaters, and so digits on that white dot must not be consecutive.

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 ;)


Thank you for your kind comments, I'm glad you persevered and were able to enjoy the experience!

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!


Thank you! I really appreciate your recommendation :)

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 :)


Thank you for solving, I'm glad you kept at it, and delighted that you enjoyed it. :)

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