The difference between an instant play casino and a no-account casino touches on the payment procedures. In most instant play casinos, players are often required to complete the signup process, which could mean sharing some personal details and sending documents before accessing the games.
On the other hand, a no-account casino allows the players to access the games without subjecting them to a lengthy registration process. As their name suggests, players are not required to have an account to play. All a player needs to do is to share their banking details.
