As a comic strip artist and designer I love drawings! In the grey thermometers, you can see one person sitting and watching another one doing a challenging Yoga exercise. Moreover, this puzzle is based on two stylized question marks, the first of which is upside down. Such an upside-down question mark at the beginning of a question is a famous Spanish phenomenon, as in ¿Qué?

I ask for your understanding of the severe pixelation of these question marks. I limited them to consisting only nine cells, which contain all the digits 1-9.

The two green squares may look natural, but in fact they are Magic. They share a corner cell. The centre cell of the biggest one is green, but you can’t see that, because it’s covered by an importunate Question Mark.

Of course, normal Sudoku rules apply. The digits in the thermometer shapes must be strictly increasing in each cell from the round bulb to the flat end.

This puzzle is dedicated to Thùy Dương, a great math mind.
