These include mechanical puzzles such as Rubik’s cubes, number games such as sodoku and even card games such as solitaire.

The French expression refers to this mental challenge.
In this sense, a casse-tête is a problem that is difficult (or even impossible) to solve, or a problem that is so annoying it becomes a headache.
