Tricky is a skill point on Rilgar in Ratchet & Clank. The skill point can be obtained by completing a Twisty McMarx at the Hoverboard race. In the high-definition re-release of Ratchet & Clank on PlayStation 3, both the stand-alone game and The Ratchet & Clank Collection, completing this skill point is required in order to gain the Trophy, Twisted Hoverboard.
In order for this skill point to be completed, Ratchet has to spin while entering the following buttons: R1+L1+R2+L2 or L1+R1+L2+R2. A whole rotation must be completed before the next button is pressed. The two most effective ramps for completing the whole trick are the large one at the middle of the track and the far-left ramp at the end of the track.
