Very interesting new game on SKY VEGAS

Here are the rules;

When the game begins, a card will be revealed.
Select Hi or Lo to predict if the next card will be higher or lower.
If you are correct, the first card becomes part of your hand.
Once you have predicted correctly five times, you will have a five card poker hand.
If that hand is good enough, it will qualify for a prize.
You can play on to improve your hand, replacing cards from your hand as you go.
Continue playing until you either collect, guess wrong or best of all, reach a Royal Flush.

If you are playing for £1 or more, you qualify for the Progressive jackpot.
To win it, make a Royal Flush in each suit at least once in separate games.
Royal Flushes achieved are remembered between sessions.

When the Ace Of Spades is revealed on the top of the pack, you will receive a bonus of either x1 or x2 of your stake.
You can continue your game as normal. The Ace Of Spades Bonus is only paid for stakes of £1 or above.

If a Hi / Lo prediction reveals a card of the same rank as the card guessed on, that is deemed correct.
Aces are both Hi and Lo so revealing an ace after a prediction will always be judged correct.
This also means Hi / Lo predictions on aces cannot lose.

If you make 52 correct predictions, the discarded cards will be reshuffled and used again.

Payouts are;

Royal Flush --- 300 for 1
Str Flush --- 100
4oK --- 40
FH --- 10
Flush --- 7
Straight --- 5
3oK --- 3
TwoP --- 2
JoB --- 1

Obviously playing through a single deck looks good, is this in anyway countable?
Should you always shoot for the Royal?
The ace of spades can make any hand a free roll.

I will add a video at some point for the guys in the US
