Instructions:
* Horizontal, vertical, and diagonal lines connect circles of the same color.
* A move is made by selecting a column. Any color match with at least one of its two circles in that column will have them shrunk.
* Roughly, circles in between will change to that color and gaps in between will create circles of that color.
* Roughly, when a stack of circles lands, it will be automatically selected with behavior as above.

Dont have a Iphone and my Thrive is used before my Ipad so I cant test for you, butthought I would give a comment anyways. I do like the color/gem/shape matching games and it appears you have mixed it up enough to make it a new twist.. but .. and I really say this with no malice. I checked your youtube page out and I still dont understand it. My guess its a game you grasp while playing and thats fine, but just watching its moving so fast I just dont get what you are doing .

it appears colors match with the lines, and if you tap it a large circle shrinks to a meduim, a meduim to a small and small disappears for points (this works on all circles connected by lines). Or can you match off colors as long as the circles are the same size?

if i had any real input I would say, at start of game some static pictures of waht matchs and and maybe what doesnt.. say a "do this" and show a pciture with some matchs, and "NO" with a pictuer of what doeasn match. then maybe a picture of a set of circles and when you press, what happens (shrinks?). And my last comment.. you have a fairly colorfull game.. but to stand out you need some "SPARK" if it was me i would change the graphics up a bit.. maybe chips on a circuit board.. an the lines some animated elctricity looking stuff.. Of course if you are going for a simpler , more clean look.. what oyuhave does work just fine.. and there is something to be said with a clean easy to see look.. sometimes busy is just that.. overdone.
