So, as you might know, the Christmas season is coming up. (17 days until Dec. 1 at the time of writing)

I’m thinking of posting some Christmas-themed puzzles during that season, and just want some feedback for a test puzzle that I created around a week ago before I make the actual puzzle.

I did have a few friends of mine try the test puzzle, but they all were unable to complete it for some reason.

Here’s the puzzle (note that it should have a 100% unique solution, even with 24 of the numbers missing):

Now, as you might be able to tell right away, this is a Nonogram/Picross combined with a Hidato. You might be able to tell that this is also based off of my most recent puzzle, which used a cell color gimmick that made it so I could have only 6 digits on the board to start off with and it still would have a unique solution. Here is what the colors here represent:

• If a cell is $\color{red}{\text{red}}$, that means that the number in the cell is a prime number.
• If a cell is $\color{green}{\text{green}}$, that means that the number in the cell is a square number ($\sqrt x$ must produce a number $\alpha$ where $\alpha\in\mathbb N,\alpha\ne x$)
• If a cell is $\color{yellow}{\text{yellow}}$, that means that the number in the cell is a cube ($\sqrt[3]x$ must produce a number $\alpha$ where $\alpha\in\mathbb N,\alpha\ne x$)
• Otherwise, the cell is $\color{white}{\text{white}}$ because it does not satisfy any of the above conditions.
• Note that the cells are uncolored to begin with.

Rules of Hidato

Fill the grid with a series of consecutive numbers adjacent to each other orthogonally or diagonally. All tiles are required to be filled in.

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.

Hint if you are having trouble solving:

Solve the Nonogram first to avoid possible confusion.
