This spanish movie start really good. The characters are clearly defined, and the mystery hooks you in really quickly. Despite its low budget, the single room trick works really well, as it quickly turns from a nice and cozy place to a death trap, and basically that's all you need.
Sadly, the resolution of the movie doesn't make much sense, and to be honest the whole plot is overly complicated, I'm not going to get into details in order to avoid spoilers. My main gripe is that the movie doesn't exploit the mathematicians enough, you barely know what the extent of their skills are and the riddles aren't all really... mathematics. Still, they get you on your toes, which it's what they're for, so they do the job.
It's a rather short movie so it's good for a quick and fun ride, check it out.
