Let me say in advance that, even it is a general audience movie it does the best with a bit of maths on the background, but still a very good movie indeed.
The strongest point are the top performances of Lluis Homar and Federico Luppi, finest actors very skilled in theaters and movies, supported by unexpectedly good beginners, Santi, Elena & Alejo, more trained in plain roles of teen comedies and late shows than in cinema, they do quite well and finally you understand why were they chosen for this film.
The plot is atracting from the very beginning, the most of time it goes on real-time action, with a countdown that will kill many of them if several mind games are not achieved. A new shape for a known theme, yes, but it works 100%.
And now the maths class: Every character is playing a role of a great mathematic and both players and characters were selected to fit into that role: Hilbert is an old mathematic devoted to the riddles, Pascal an engineer thinking only on the commercial application of any idea, Fermat an enigmatic person showing no more that what you want to see and Galois a young genoius but not used to think on advance. The life of those people plays a little on the movie. So now you can see what a good selection of players for this roles.
The mathematical riddles are explained easily and with no so much relationship with the main plot so they are not required to be understood to follow the film, but of course is a good point if you do it.
And finally, the Fermat's Last Theorem: It is already demonstrated so don't expect any surprise on this movie. But if you want, you can take a look to the Goldbach's Conjecture, maybe it helps.
