Phil’Em Up Poker

Posted in collusion by stephenhow on April 19, 2013

When I playing Mississippi Stud in Vegas last week, I overheard someone mention a game called Phil’Em Up Poker. I looked at the game, to see if collusion would yield an edge. The rules are pretty simple. The game is played with a 52-card deck plus a Joker which may be used for Aces, straights, and flushes. Each player bets an Ante, and receives two hole cards. Two community cards are dealt face up. Each player may either make an additional 1x bet (i.e., “double-up” his action), or check, before the 3rd community card is exposed. If a player makes a pair of Tens or better, he wins according to a paytable. There is no dealer hand. The house edge is a reasonable 3.3%.

Collusion doesn’t help. That’s because only 3.8% of hands are bet on a draw only. Collusion will change few decisions, and result in little gain. With 7-player collusion, perfect play will only reduce the house edge to 3.2%.

    Your post says the joker can be used for Aces, Straights, and Flushes, but the rules you linked to say the joker can be used as an Ace or to complete a Straight Flush. Which is correct? Can the joker be used to complete a regular straight or flush?

      I called the Golden Eagle Casino in Saskatchewan, and they told me the Joker can be used for Aces, straights, and flushes. I didn’t call any South Dakota casinos about the game.
