No I think the biggest is 800k.. because the play I got is only normal cards, I haven't putted III and XI cards that makes it quadruple the earnings if I won on the same conditions I stated on the first post:D
I got the 200k a few times, 150k and 100k several times, and 20 and 15k more times than I care to count.
Then I got out my turbo controller and racked up a few million while I read. Tried using the III and XI cards for a while, but my net gain was slower. Total winnings was over 3.5 million with an initial purchase of 200 medals, betting 10 at a time, then 20, 50, 150, until I could steadily bet 1000 at a time. The odds over time are totally in the player's favor, unlike any other game's casino.
