VEX Skyrise is played on a 12’x12’ square field configured as seen above. Two alliances – one “red” and one “blue” – composed of two teams each, compete in matches consisting of a fifteen second autonomous period followed by one minute and forty-five seconds of driver-controlled play.
The object of the game is to attain a higher score than the opposing Alliance by Scoring your colored Cubes in Floor Goals, on Posts or on your Skyrise, by Owning Posts, and by Building your Skyrise Sections.
There are a total of forty-four (44) Cubes, twenty-two (22) red and twenty-two (22) blue, and fourteen (14) Skyrise Sections available Scoring Objects in the game. Most Scoring Objects begin in designated locations on the field, while some are available to be entered into the field during to the Match.
Each Robot (smaller than 18”x18”x18” to start) begins a match on one of their Alliance Starting Tiles. There are ten (10) Posts and four (4) Floor Goals that Robots can Score Objects onto. The Alliance with the topmost Cube on a Post Owns the Post. Alliances also earn points for Building Skyrises on their Skyrise Base out of Skyrise Sections, and Scoring Cubes on Skyrises. A bonus is awarded to the Alliance that has the most total points at the end of the Autonomous Period.
