The stake/prize level of a skill machine is also a grey area, as there is no legal limit on either, although most manufacturers abide by a gentleman's agreement with BACTA (a trade organisation) to limit both amounts to levels that are unlikely to attract the attention of legislators. Skill machines can legally be sited anywhere and played by anyone of any age, although there seems to be a lot of confusion about this, with some people assuming age limits and site restrictions must exist because of the similarity between these machines and AWP ("amusement with prize") machines, such as one-armed bandits.
