Official description:

Video games that show violence of a slightly more graphic nature towards fantasy characters or non-realistic violence towards human-like characters would fall in this age category. Sexual innuendo or sexual posturing can be present, while any bad language in this category must be mild. Gambling as it is normally carried out in real life in casinos or gambling halls can also be present (e.g. card games that in real life would be played for money).

12 is part of the PEGI Rating category. The Pan European Games Information (PEGI) age rating system is a pan-European age rating system for interactive games that came to use in 2003, replacing most individual European rating systems (with the notable exception of the German USK). Designed to ensure that minors are not exposed to games that are unsuitable for their particular age group.
