Learned the rules on YouTube

I downloaded the game because of the tie quests. I almost gave up because it was all in English, but the rule explanation in the Koyabu video on YouTube was easy to understand. I still don't know anything other than Texas Hold'em and Blackjack though. I reached 1 billion in the hidden quests and then the tie quest disappeared. I'm wondering what to do since the next hidden quest is quite far away.
