Yes, that queen slime (introduced in DQ10 as a normal monster) randomly helps you out. I always spend a long time in this casino even before the MMA.
I also figured it out at 18:25. You don't have the passwords for new games in the English version so somewhere in the game you can find the items we can only get with those passwords in the original (like that tombola ticket). I've seen this about the Princess Pledge before and wondered why it's only in the oversea version.
With the tombola ticket, you can win some few gold coins, not too many but you can use it as much as you want.
