In heads or Tails, you play as Sazh who is stuck in Serendipity. To escape (and gain Sazh as a party member), you need to collect a certain amount of Fortune Medals. Unfortunately, I skipped from four medals to 56 medals before checking with the owner of Serendipity so I'm not sure how many you need but I would guess anywhere between 30-50.
You have your choice of three different methods of collecting the Medals, Poker (hold'em), Chronobind and Chocolina who is now in the sage's building (as well as slot playing if you want to try to use that to drum up coins).
I can't say I'm sure how to get the most out of Chronobind but it's a fun game nonetheless. If you really want to get some medals though, you should hit the poker table. The AI for poker (at least at the 1,000 coin buy-in) is incredibly simple. To beat them, you simply have to keep betting heavily and they'll fold almost every time. When they don't, you can be sure they have a hand. So far, I don't think I've made it to the River without my opponent having a pocket pair. In fact, I've frequently seen them fold after the flop with no betting (in other words, they could have checked but they chose to fold). Usually that means I do a 4x raise and then if it goes to the flop, I check or fold unless I have good cards.
There are two strategies here. You can raise x4 every hand and slowly bleed them away or you can go all in for the same effect. The difference is that every All In will get you a Fortune Medallion HOWEVER, the rules that govern all in are different for you than they are for the AI. If you go All-in and win but have fewer coins, you will only get the amount that you could actually bet. However, if you have more than they do and lose, you will lose everything. I lost over 3,000 coins to someone who only had 55. Use this information wisely.
When you get to heads-up (1 on 1), you can usually raise x2 and then check after the flop. This will generally lead to the AI folding. Very rarely will it check and I don't think I've ever seen it raise over my check.
I had 56 Medallions after this. I got 34 from my struggles, 8 from all-in bets and 7 from winning streaks and the rest were minor amounts or from separate games.
Chocolina will ask you to find her Chocobo chicks for her. You'll have to talk to her until she gives you a tip on where the first one is. The first is by the Chocobo Racing room (it looks lost), the second is on the balcony where there is normally a time gate (Come with me), and the third (that's all that have appeared so far) runs around the middle area until you catch it. Catch it and it heads to the gaming room. Catch it there and it heads outside again. Keep catching it until it joins you.
I've only found three so far. The game tells me to keep playing games and come back later. My guess is that there are more since the chicks names have so far been lining up with the Deadly Sins. If anybody has information on them, please contact me with how to unlock them (more coins?)
When you finally collect 30 medals, you'll be free of Serendipity and have Sazh in your party. He's a fantastic Synergist. He has a lot of different skills to use but of huge importance or the En-elemental abilities because neither Serah nor Noel has access to them meaning he's the perfect complement for the few occasions when you need the third party member to be a Synergist.
