This is a Friday puzzle. On the left, there is an irregular sudoku with numbers 1 through 8. On the right, there is a fillomino puzzle. Note that the two solid bars in the fillomino represent borders of some polyomino, in other words, they may not have the same number on both sides. The numbers in the middle represent how many places in that row would contain the same number if the two puzzles were overlayed. For example, if the sudoku contained “12345678”, and the fillomino contained “12288771” the number in the middle would be a 3, 1 for the ‘1’ in column 1, one for the ‘2’ in column 2 and one for the ‘7’ in column 7.

Now for the solution last meta of last week’s theme. One person noticed that “Metaphor” has the sound of the number 4 at the end, “Tutorial” has the sound of the number 2, and “Don juan” has the sound of the number 1. They were looking to find a 3 in the word “Atypical” and got stuck there.

The trick is that the numbers in question were not 1,2,3,4 but instead 1,2,4,8 which checks out as the sound of 8 appears at the start of “Atypical” which gives us the ordering. Also, each word has exactly 8 characters, so it is natural to index these numbers into the words, giving:

**D**on Juan- t
**U**torial - met
**A**phor - atypica
**L**

**DUAL** which is thematic for the powers of two.
