All the above mentioned slot's name seems to be from single provider "Play n Go". I think it is a global promotion by the provider and any player can participate no matter where they play the game as long as they play the qualified game with the minimum bet requirement. Surprisingly I cant even find Play n Go in the providers list at Livecasino and I cant even find the games by using the search bar, am I missing something here? One more thing, this is also not a simple multiplier contest because it is being said that it is "Sum of highest wins in relation to bet". Means that it is not based on a single highest multiplier like other normal multiplier, but it is like combination/total multiplier for many bets.
