dropsum07A few months ago iPhone developers must have gotten a memo that the next big trend in iPhone gaming are math-based games, and they must have been working hard since that time.

DropSum is one of the better ones to arrive in the App Store and is based on a Flash game of the same name. The game also bears a resemblance to Drop7, but the goal here is to simply create adjacent numbers that add up to 9. Each numbered disc changes color as it's involved in more matches. After three times, the disc explodes and the remaining numbers fall into place potentially causing a chain reaction.

The game was well designed and includes a local high score and achievement system. The developers have promised a global high score in a future update. Check out the developer video below or check out the Flash version. Note the iPhone version only appears to have the "Basic" playmode.

    Actually while almost identical to the Flash Basic Mode, the iphone version has a Blast powerup (not sure exactly what it does other than maybe deleting the tile underneath it).

    Ob. grammar fact: "bares" is incorrect. A thing bears a resemblance to another thing, it does not 'bare' a resemblance. The resemblance is not revealed or uncovered, it is carried, conveyed, or featured. Thus the resemblance is born, not bared; the game bears a resemblance to drop7, it does not bare it.

    Some info on the power tile - you can get the power tile by destroying 10 or more tiles in one move. Once you get the power tile you can swipe it down onto a column, doing so will result in it destroying the tile it lands on and then dropping into its place. Alternatively you can drop the power tile normally and save it for your next turn. Handy to use for numbers that are in the way.

    You can get more points by destroying octagon tiles. These tiles come up in the queue every so often. Destroy one and a star will float up to the top left and last there for about 15 seconds. Destroy another octagon and and the timer is reset and another star floats to the top. When the time runs out or you end the round these stars will be collected. The more stars you have the greater the bonus points.

    Update for the global high scores will be submitted within the next few days.

    Hows the sound?

    Listening to the demo it seems like the sound effects and music may get irritating after awhile?

    Horrible game. Very long load time. I kept running into a bug that would keep me from being able to drop a number. Feels like a bad port.
