Pokerbo, a game with a negative house edge bet

So has anyone heard of Pokerbo, it's advertised as a mixture of sic bo and poker. In it they deal out a 5 card poker hand and you can bet on the results, i.e. pair, straight or better, etc. The bet of interest is the 'no pair's bet, which pays even money. I believe it has a negative house edge (albiet very small). This table is currently in Crown Melbourne in Australia as far as I know, with a $2000 max bet.

Here is the rack card for the game. Does anyone know if the straight and flush bets win on a straight flush?

The John Huxley site has an information sheet that says the straight flush and royal flush do not pay on the straight and flush bets. The straight flush bet does not win on a royal flush. Six decks are used. On hands that win more than one way, for example a suited four of a kind, only the higher/highest hand pays. The information sheets indicates the odds of each bet. This should be an easy analysis. Stay tuned.

All right, I hope you're happy, here is my new page on Poker Bo. Bottom line -- I'm not finding this bet with a player advantage.

Thank you so much for your time (and for your sites in general, a fantastic resource). My confusion came in that I assumed the game was played with 1 deck, I have double checked Crown Melbourne and it is as you say, 6 decks. Thanks again.
