Horizontal Bars (スプリングポール Supuringupōru?, lit. "Spring Poles") are gimmicks that appear in the game Sonic Generations. They are used to launch Sonic higher into the air in order to reach shortcuts or send him flying across gaps that otherwise cannot be spanned.
Horizontal Bars are usually seen in two-dimensional sections, held in place by a pole in the background. In order to grab a Horizontal Bar, Sonic must either jump into it or use his Homing Attack. Once he has grasped it, a circle will appear around the bar. This circle is mainly yellow, with a blue section in the front. As Sonic swings around the bar, the circle lights up according to Sonic's alignment with the bar, similarly to a Plan Position Indicator radar display. The player must press / when the part of the circle that is lit up is in the blue section. If the player presses the button at the correct time, Sonic will be launched forward and upward; however, if the player presses the button too early or too late, Sonic will be launched forward and downward with much less speed.
The only times Horizontal Bars appear in three-dimensional sections are in the Challenge Act "Cream: Helping Hand" and the Seaside Hill Challenge act "Surf, Sea and Sand". They function exactly the same, but the circle that appears is slightly harder to read due to the camera angle. There are no poles holding the bars.
