Puzzle Pirates is deceptively complex. The number of statistics and rankings that can be affected by playing the games is utterly voluminous, and it isn't immediately clear, aside from enabling you to play more complicated or challenging versions of the same game, what benefits this provides. One key element, though, is that the basic experience is fully available to everyone, doubloons or not, no matter how fully invested they wish-- or don't wish-- to get. With most of the job-games available from the mission board, Puzzle Pirates could be just a particularly elaborate content delivery network for fans of casual games.

And it wouldn't make such a bad one -- the games are quite good. Most of them are elaborations or twists on familiar puzzle-game formats like Snood, Bejeweled or Tetris, but they're all consistent with the oceanic, swashbuckling theme. The bilge game has attractive turquoise-patterned tiles, and the sailing game, which involves rotating and fitting together sets of interconnected pieces, looks like seashells and jewels. This is all bolstered by pleasing ambient sound effects -- the sound of the wind filling the sails when you score, or the rush of the ocean or burbling of water as your puzzle progress helps the team sail the ship.

It's a refreshing change from the clumsy over-simplicity of other puzzle games in worlds for young people; with a difficulty level that advances with your experience and a polished interface, they're all games that adults and kids could find equally engaging, rather than just being a slapdash conveyance to earn points or gold. Since the puzzles, logically enough, are the centerpiece of the Puzzle Pirates world, this makes good sense.

The rest of the interface is not so clean. Navigation in the world is a little jerky with the mouse clicking -- it'd be nice to have an alternate control set using the keyboard. You need to be standing within a certain radius of another character to converse with him or her, and if too many other characters are in that "circle" you won't be able to join in. There's no way to pan around an area while standing still, so you often can't see what's ahead in very expansive areas until you walk that way.

The play screen is a bit busy, too. Though everything's consolidated on one main screen, with the menus in one compartment with chat and notifications below them, the map above, and play in the main window, means you have to learn to juggle looking in more than one place at once. Sometimes chat bubbles take place beside the appropriate avatar in the play screen, and other times it appears in the chat window. You may have to respond to a notification in the chat window by clicking a button in the play window for one purpose, and then for another it'll be a button in the menu or a pop-up on the map screen. If, focused on the play window, you miss a notification, you might be stuck until you figure what it was you were asked to press and where (and what for).

The basics are very intuitive -- the games can be learned fairly easily by playing them, and most everything is point-and-click. While there is some tutorial given, it could be a little better integrated -- NPCs will give you loose explanations, but the details are not always clear. The first hour in the Puzzle Pirates world might feel a bit like shooting in the dark, although the learning curve can be quickly climbed merely through experimentation.

The only major peeve about the games themselves is the pop up "Duty Report" that appears every few rounds (or, leagues you sail) to let you know how you and the others on your team are performing with the ship's tasks. It can be challenging to be maneuvering a difficult piece into a tricky spot when all of a sudden you're interrupted by this game-obscuring screen on a fairly frequent basis, and you can't close it yourself. It's easy to have forgotten where in a move you were paused by the time the Duty Report closes, and since the games are so immersive and addictive, sometimes the Duty Report feels like an infuriating interference with your "fix."

All of the technical clumsiness seems insignificant, though, in light of how fully-realized the Puzzle Pirates world is. The pirate thematics are outright adorable in their detail, and site literature encourages users to talk "pirate-y" by inserting "Arr," into sentences and calling one another "matey."

The social hierarchy is a rather fascinating concept, as is the idea of forming teams to own a ship and send it to war. Complicated opportunities for long-term players are vast, and it seems to be very rewarding to invested users. YPPedia, Puzzle Pirates' official Wiki, is rich with content and provides a charming insight to what the game means to its players; a huge directory of fan-contributed character art shows how strongly users connect to their experiences in the world, and it's not surprising -- through the natural progression of entirely user-generated play, some pretty exciting and dramatic character stories can take place, since all the right ingredients are there: rags to riches stories, adventure and danger on the high seas, and climbing the ranks of proficiency in a variety of crafts.

Since you're not penalized for selective involvement, users can tailor their Puzzle Pirates experience -- they can simply play games with others in a charming environment, or they can invest personally in the games' outcome, form friendships and pursue advancement. It's a tenderly-drawn and adventuresome environment that's solid where it counts.
