It is illegal to organize games of chance in Belgium if you don’t have a license from the Gaming Commission. If there is no stake to participate, the game, competition or raffle does not count as a game of chance and you do not need a license from the GC.
For your game/competition/raffle to meet the legal definition of a game of chance you need to meet the following criterias:
– A monetary stake (a sum of money) to participate
– The possibility to lose or win
