Recently, I created my first Hokuro puzzle, which was received really well. However, this time, there is a twist! Not with the rules or anything, however, it is combined with a Nonogram! Luckily, the sums of the movements indicated by the symbols in the corresponding row/column are already given. (except for one that can be easily deduced using )

Rules of Nonogram/Picross:

The grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden pixel art-like picture.

The rules of Hokuro:

  • Each cell contains each of the following cells:

  • enter image description here

  • Each arrow indicates a step in that direction, while the dot indicates no movement.

  • The clues in the black cells show the sum of the movements indicated by the symbols in the corresponding row/column.

  • Symbols in consecutive white cells must be unique (a 'sum' cannot contain the same symbol more than once)

In some cases it might come in handy to sneak a peek at the Hokuro Cheat Sheet.

  • $\begingroup$ For anyone who solved the Nonogram, I imported the Hokuro into Google Sheets for whoever prefers to solve it this way: docs.google.com/spreadsheets/d/… It is the sheet titled "Twist Hokuro". One way to use this is to select File > Make a Copy in the menu bar. $\endgroup$

Solved nonogram (black denotes filled cells, grey denotes empty ones):

enter image description here

Hokuro with colourings included (grey denotes "black" cells this time, white denotes empty ones):

enter image description here

Filling in single cells (btw I missed one in the upper right, which is included in the next image instead):

enter image description here

Some more easy deductions, and one cell highlighted in red for the next deduction:

enter image description here

That red cell is part of "down-right in 2" and "up-right in 2", so it must be either a dot or a right. It's next to a dot, so it must be a right. We continue:

enter image description here

(Note that the bottom left corner now can't be filled uniquely: there are two different options, as far as I can see.) Sorry, I realised that this part can be solved uniquely, see the final image.

The green cell is part of "left in 2" and "up in 2", so it must be either a dot or an up-left. If it's an up-left, then the blue cell must be a right, the next one must be an up, the next one must be a down-right, contradiction. So the green cell is a dot, the blue cell is an up, the next one is a right, the next one is a dot, and we continue:

enter image description here

As far as I can tell, the top right cells don't have a unique solution. We have two different possibilities for the overall solution, shown in blue/red in the following final answer:
