iWin68 - ZigZagBall Iwin

In iWin68 - ZigZagBall, you direct a small black ball along a jagged line. Tapping on the screen moves the ball from left to right, and what I thought may be fairly simple, was actually incredibly difficult. The ball moves very fast, and with the taps of your finger being measured very well, just a slight graze of your finger on the screen will send your ball right over the edge.
