The content of games with a PEGI 3 rating is considered suitable for all age groups. The game should not contain any sounds or pictures that are likely to frighten young children. A very mild form of violence (in a comical context or a childlike setting) is acceptable. No bad language should be heard.
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).
Game content with scenes or sounds that can possibly be frightening to younger children should fall in this category. Very mild forms of violence (implied, non-detailed, or non-realistic violence) are acceptable for a game with a PEGI 7 rating.
This rating is applied once the depiction of violence (or sexual activity) reaches a stage that looks the same as would be expected in real life. The use of bad language in games with a PEGI 16 rating can be more extreme, while games of chance, and the use of tobacco, alcohol or illegal drugs can also be present.
The adult classification is applied when the level of violence reaches a stage where it becomes a depiction of gross violence, apparently motiveless killing, or violence towards defenceless characters. The glamorisation of the use of illegal drugs and explicit sexual activity should also fall into this age category.
A U film should be suitable for audiences aged four years and over, although it is impossible to predict what might upset any particular child. U films should be set within a positive framework and should offer reassuring counterbalances to any violence, threat or horror. If a work is particularly suitable for pre-school children, this will be indicated in the BBFCinsight.
General viewing, but some scenes may be unsuitable for young children. A PG film should not unsettle a child aged around eight or older. Unaccompanied children of any age may watch, but parents are advised to consider whether the content may upset younger, or more sensitive, children.
Films classified 12A and video works classified 12 contain material that is not generally suitable for children aged under 12. No one younger than 12 may see a 12A film in a cinema unless accompanied by an adult. Adults planning to take a child under 12 to view a 12A film should consider whether the film is suitable for that child. To help them decide, we recommend that they check the BBFCinsight for that film in advance. No one younger than 12 may rent or buy a 12 rated video work.
No one younger than 15 may rent or buy a 15 rated video work.
No one younger than 18 may rent or buy an 18 rated video work. Adults should be free to choose their own entertainment.

In the year 1905, Albert Einstein published the theory of special relativity, suggesting that nothing could move faster than the speed of light. What if any mortal could break that constant? Stretch it beyond its limits? Would human beings finally be able to find a way to cheat death and win over immorality? Or is it Chaos that follows the manipulation of time and gravity?

 Constant C is a 2D puzzle platformer with two core gameplay mechanics - Gravity Shifting and the Time Field. Using these two mechanics in the game, the player controls the momentum of various objects to complete each level.

Dive into the world of Constant C, where rules of fundamental physics no longer apply. In a space station far away from Earth, mysterious events have triggered the distortion of time. Journey through the game as a lone robot, who uncovers the truth behind the incident step by step, and finds the purpose of his own creation.
