Ordinary raffles are held using physical numbered tickets. The winners are determined by manually selecting numbers from a container or by using a mechanical device for this purpose. Online raffles use special software solutions that automate many processes: selling tickets, randomly selecting winners and distributing the prizes to the winners. Since most of the tasks are performed by the software, it has to be certified which confirms that the random number generation algorithms work correctly. Only certified raffle platforms ensure a fair and transparent gaming process.
