In English, this means that a player must have made a deposit at a partnering casino before they can participate in Captain Cooks free spins promotion.
So if the only casino rewards casino they have played in is the Casino Classic free spins, and they made a deposit, they are able to play Captain Cooks free spins. If they didn’t make a deposit in the Casino Classic, but have made a deposit in another of the casino rewards casinos, they are able to play Captain Cooks Free Spins.
The promo is valid for new players (to Captain Cooks) only.
I hope this clears some confusion. Basically, as long as the player has made a deposit at a casino other than captain cooks, and has never played or held an account at captain cooks previously, they are able to play the captain cooks free spins.
Please let me know if this is still unclear.
