The final day of the year is typically a time of reflection. Naturally, that calls for a puzzle about reflecting things! This is Kin-Kon-Kan, a puzzle about placing mirrors. Draw a diagonal line in only one cell within each region.

As you might have noticed by now, I love the various cell-shading puzzles. Today, we’re taking a look at another Nikoli creation – Stostone. In English, it’s generally known as Stone on Stone. Like Heyawake, you must shade cells according to the numbers in the regions, but there are a few unique requirements.

One common Christmas decoration, especially in the southern United States, is the poinsettia flower. In honor of that, today’s puzzle is Flower Sudoku. This is five overlapping Sudoku grids, in which the central grid is completely covered by the four outer grids.

On this beautiful winter’s day, let’s celebrate with a dance in the snow! Today, this arrangement of snowmen will represent your dancing partners.

Draw a single loop which passes through every cell of the grid, turning every time you pass a snowman, and once between each pair.

Kakuro is another popular Japanese puzzle. Another popular name is “Cross Sums,” because it functions similarly to a crossword puzzle. Fill in the grid with the digits 1-9.
