Weirdly theres not an adequate explanation of how the game works in the App Store (before you buy).
One line—colour changes—flicks around the 4 colour-segmented dial. You have to tap when the line colour matches the dial segment. Miss by a smidgen & the games over.
It flicks very quickly!
$0.99 is NEVER too expensive to remove ads.
