There is no statutory definition of what constitutes a substantial degree of skill. We would advise anyone who plans to promote such a competition to seek legal advice. There are no restrictions on who can run a prize competition. There are no statutory rules on ticket requirements for prize competitions. The rules are solely the responsibility of the promoter.
Competitions are, of course, subject to the more general law on theft, deception etc.
It is not possible to say how the law would apply in particular cases. It is possible however that a court could decide that the chance element contained in the draw would qualify that part of the competition as an illegal lottery. There are no registration requirements for prize competitions. Those seeking to promote them are, however, advised to seek their own independent legal advice, before proceeding, to satisfy themselves that a scheme is not in breach of section 14 of the Lotteries and Amusements Act as amended.
