Unibet's little sister, Maria Casino, grew out of Maria Bingo with bingo and some casino games.

The team created a brand new casino with a wide range of games from Net Entertainment called Maria out of a desire to introduce the brand to a wider audience and be of interest to more online casino visitors.

Today, however, the selection of games at Maria Casino is already much wider, and Maria Casino is now a fairly well-known casino for Estonian players.

Since 2010, the former bingo website has been operating as a casino, keeping the features that made working with Maria Bingo convenient and enjoyable.

On the Maria Casino page you can see your gaming history, keep track of your wins and losses, plan the best strategies to play smart and choose the right way to win for you.

It's also easy to find your favorite games - whether it's video slots, live roulette or interactive bingo, table games or video poker, the choice is yours.

Next, we'll get to know Maria's and its offerings in more detail.

Maria's Casino is a brand owned and operated by Unibet (Trannel International Ltd). A company duly registered under the laws of Malta.

Tournaments at Mariacasino Casino

Tournaments are constantly updated. When one tournament ends, it is replaced by another. So real gamblers will always find ways to have a decent entertainment.
