Besides the fun puzzles, Puzzle Pirates has a large social aspect involved with Crews and Flags.

You know how your parents (or teacher, or someone) told you that gambling was bad because even if you win, you lose a lot more often. For 80% of the population that is definately true. I couldn't count the number of people I know who've gone broke from poker.

That somehow doesn't manage to make it less fun, or enticing.

And on the other side of that, the richest pirates in viridian tend to be poker players. (And thats about it)

Poker on Puzzle Pirates is your basic Texas Hold 'em rules.

If you've been playing online games for awhile, you'll notice that there are groups of players in almost everything. Whether they go by the name of "clans" or "guilds" in the end its just a group who play games together.

On Puzzle Pirates, there is a deeply engrained system for this known as the Crew system. Basically, its just a group of players in a hierarchy of ranks that give them different abilities.
Cabin People are your basic swab-the-deck entry level types.
Pirates have access to the Gunning Puzzle
Officers can lead pillages in ships
Fleet Officers have access to the holds of all the ships.
Senior Officers can edit the crew info and in oligarchic crews vote on all alliances, promotions, etc.
Captains have the ability to rename ships and create Flags.

Which brings us to the next subject!
Flags are groups of crew which have joined together. They have the ability to declare war on other flags, which means if the crews within those flags start fighting eachother, ships can sink!
Also, if they build up enough fame and money, Flags have the ability to blockade islands in an attempt to take them over.

Puzzle Pirates has two kinds of oceans. (for those of you who play other online games, oceans are like shards, servers... etc.)
The two types are Subscription and Doubloon. The subscription oceans are pretty straight forward: You buy a subscription. Monthly fee. Much like other online games.

The doubloon oceans, on the other hand, are free to play on. Many purchasing actions, however, require use of doubloons, which must be purchased using real money. By someone at least.
You can do everything someone who buys dubs can if you don't. You just need to buy doubloons off of other people.
