Slides & Grinds is a version of the game of SKATE but instead skateboarders battle on a ledge with either a slide or grind. After an introduction of the contenders Sean Malto vs Mike Dias in Portuguese, Carlos Ribeiro goes over the rules (0:47):

A coin flip decides who starts first, skaters on offense has to alternate between slides and grinds, defensive skaters have two attempts to copy and land the maneuver, and the last letter gets three tries.

Watch as Malto and Dias go mano-a-mano like a heated tennis match with their ledge prowess.
