2013 -  ULTIMATE ASCENT

ULTIMATE ASCENT is played by two competing alliances on a flat, 27 x 54 foot field. Each Alliance consists of three robots, and they compete to score as many discs into their goals as they can during a 2-minute and 15-second match. The match begins with a 15-second Autonomous Period in which robots operate independently of driver inputs. Discs scored during this period are worth additional points. For the remainder of the match, drivers control robots and try to maximize their alliance score by scoring as many goals as possible. The match ends with robots attempting to climb up pyramids located near the middle of the field. Each robot earns points based on how high it climbs.

2012 - Rebound Rumble

The field is a carpeted area 27 feet by 54 feet designed to mimic a basketball court. At both ends are the driver stations and an array of basketball hoops. There is one low hoop, two middle hoops, and one high hoop. Across the narrow dimension of the field a 4 inch high wall, along which are placed three tilting bridges at a height of 12 inches. The bridges at the edges are color coded for each alliance, and the center bridge, called the Coopertition bridge, is available for both alliances.

2011 - Logomotion

Playing pieces are inner tubes shaped like the components of the FIRST logo. The primary objective of the game is to place them on racks to gain points. In the endgame, robots deploy smaller robots ("minibots") to climb a tower. Minibots must be made from the FIRST Tech Challenge kit of parts. The game celebrates the 20th season of the FRC and is also meant to commemorate the artist Jack Kamen, who designed the original FIRST logo.

2010 - Breakaway

Robots play Breakaway on a 27 by 54-foot rectangular field known as the field. The field is bordered by a set of guardrails and alliance walls. There are two "bumps" in the field that divide it into three zones. During matches, the robots are controlled from alliance stations located outside the field at both ends. These rectangular zones consist of three-team player stations that provide connectivity between the controls used by the robot operators and the arena. Goals are located at the corners of the field, and extend behind the alliance wall and adjacent to the player stations. After goals are scored, human players must pick up the balls and pass them to the center of the alliance station to be placed on a ball return rack, after which they will re-enter play at midfield. Teams are penalized if balls are not re-entered within a set time limit.

2009 - Lunacy

Lunacy is played on a rectangular field that is 54' by 27'. This field is a material called 'Glasliner FRP' and is referred to as 'Regolith'. The regolith is designed so that the robots, which have special mandated wheels that they cannot modify in any way, shape or form, have reduced traction, mimicking the effect of low gravity that would be seen by a robot driving on the moon.

2008 - FIRST Overdrive

FIRST Overdrive is played on a 54 ft (16 m) by 27 ft (8 m) carpeted field, divided lengthwise by a fence median to create a track, and separate the field into Red and Blue zones. The fence is crossed by an overpass marking the red and blue finish lines, and hold the game pieces: 40 in (1,016 mm) diameter inflated balls called "Trackballs". Two three-team alliances race around the track in a counter clockwise direction while manipulating the trackballs to score points.

The game is made up of two scoring periods. The first 15 seconds of play is the Hybrid period in which robots are autonomous, and may also respond to certain digital signals sent by team members designated as "Robocoaches", who are stationed at the corners of the track.

The next two minutes of play is the Teleoperated period. At this time, robots are fully radio controlled by the team operators standing at either end of the field.

2007 - Rack 'n Roll

The Rack 'n Roll field is dominated by 'The Rack', a large metal contraption with three levels of hanging metal bars, with each level having 8 arms evenly spaced in an octagonal manner. Each arm (known as a 'spider leg') has space for two game pieces. Any more pieces placed on a spider leg beyond the first two are ignored for scoring purposes. At the beginning of the match, the rack is arbitrarily translated or rotated within three feet of the center of the field in order to give some randomness and to encourage autonomous modes that do not depend on dead-reckoning. At the top of the Rack are four green-colored lights above the 1, 3, 5, and 7 legs to aid in autonomous-mode tracking.

2006 - Aim High

Aim High is played by two alliances, red and blue, each consisting of three robots. During a 10 second autonomous mode robots are programmed to score into any of the three goals: one raised center goal marked by a green vision target and two corner goals at floor level. At the end of the autonomous period the alliance with the most points will gain a 10 point bonus and will be placed on defense for round two. Rounds two, three and four are each 40 seconds long and are human-controlled rounds. Between rounds two and three the alliances switch from offense to defense or vice versa. At the start of round 4 any alliance can score into the corresponding goals. At the end of the match any alliance can receive bonus points by placing its three robots on a platform below the center goal. The alliance with the most points wins with scoring as follows: 3 points for any ball scored in the center goal, 1 point for any ball scored in the corner goals, 10 bonus points for scoring the highest in the autonomous round and 25 points for placing all 3 robots on the platform at the end (10 points for 2 robots and 5 points for 1 robot).

2005 - Triple Play

This game was the first to feature three robots per alliance. The primary game pieces were called "Tetras" which are tetrahedra made from 1.25 in (31.8 mm) PVC pipe 30 in (762 mm) long. The game was played on a field set up like a tic-tac-toe board, with nine larger goals, also shaped as tetras in three rows of three. The object of the game was to place the scoring tetras on the larger goals, creating rows of three by having a tetra of your alliance’s color at the highest point on the goal. Triple Play was a strategically intensive game, requiring quick thinking on the part of the drivers and operators to optimize the field for their alliance.
