How long can you go without being bored of blackjack?

[Faizett]

Blackjack (cards) is one older games and one of the best ways to earn tickets. Which can be used to buy items at Prize and Joy and be sold for millions on the marketplace. (Depending on how much you collect and which item you buy.) However, people ignore the earning tickets strategy because it takes too long. So my question is:

How long can you go without being bored of blackjack? If you don't know play the game.

I generally play in one hour stretches. 3nodding I could probably go longer, but life gets in the way.

Ten minutes on a really good day D;

If I'm playing cards, I like to have a human to play with -- or, ideally, a more interesting card game.
