I'm trying to remember when our fascination with games that have jewels in them came about, but I really don't know. People seem to go bananas for Bejweled, and while this isn't that, it's in the same vein of games with jewels (and fun).
Star Diamonds Capture has a simple enough premise: Flip the spots two jewels are in, and while doing so, try to get three-of-a-kind in a vertical or horizontal line. When you do that, the jewels disappear, their background turns blue (your color), and your green score bar fills up.
The kicker? You're playing against a live opponent. Every time. So while you may think you're the master of scoring captures, you've got to contend with someone else's ingenuity trying to muddle your success (and always have an internet connection).
Also, you can steal squares captured by your opponent (as they can do to you), and as a result, the green score bar goes down. It's the easiest way to slow down your challenger's victory, and can seriously turn the tide of a match in a few moves.
You can also put together impressive combos, as falling jewels just happen to land in the perfect spot, but I'm not sure how predictable this is or if it's sheer luck. Regardless, it's the quickest way to win, and whenever you make your move, you'll anxiously wait to see if any more combos are coming your way.
When you're not in-game, you can check out your stats by hitting the Star Arcade logo in the top-right corner of the screen, like recent games, rank, and wins and losses. There's also a buddies list, a basic settings menu, and an in-app store that hasn't been implemented yet. I can only assume the points you earn from winning games will be spent in the shop, but I wouldn't be surprised to see in-app purchases, either, since those are all the rage these days.
Diamonds Capture is a pretty fun (albeit unoriginal) take on the three-of-a-kind jewel games, but the fact you're always facing off against a human opponent adds a great dynamic to the game. Diamonds Capture is 99 cents in the Android Market.
