Panic rings are one of the seven types of skill rings in O2Jam. It is classified under "Arrange rings".
Effect[]
Unlike the Random ring, the Panic ring randomizes the columns of a song per measure. The Panic ring does not randomize a measure if a long note from a previous measure is continued to that measure.
Reception[]
The Panic ring also appeals more to the skilled players, and can be considered a competitor of Random rings.
