As noted by iPhone Central, the iPhone web-version of Frenzic has been published at http://frenzic.com/iphone/. Frenzic is described as a fast paced puzzle-based game originally developed for Mac OS X.
As colored pie pieces appear in the center, place them in the outer circles to earn points. Pieces can only be placed into circles that have a corresponding open slot. Once all six slots of a circle are filled, the completed pie is cleared from the board. If a piece is not placed before the timer expires, a life is lost
Use the fewest colors possible when forming pies for maximum points as each piece of the same color is worth more than the one before it. Pies completed with a single color also earn an extra life. The speed of the timer gradually accelerates, increasing difficulty. Play ends when all of your lives are lost.
