Can a prize promotion be run where there is an element of chance in the selection of the winner?
Not without a permit. Namely, if a prize promotion includes an element of chance in the selection of the winner, it may be considered to be a lottery or a promotion lottery, which requires obtaining an official permit under the Gambling Act.
Under Polish law, a game will be deemed to be a lottery where the outcome is significantly dependent on chance (the main condition), the prize is either cash or a physical prize (there is no legal definition of a physical prize under the Polish law, however a prize is considered to be physical if it is neither cash nor its equivalent (e.g. gift certificates, vouchers etc.); thus, for instance physical prizes are cars, books, trips etc.), and participants purchase goods, services or another game ticket to enter the lottery.
