The general match format has changed several times throughout the years.
- 1992-1998: 1v1v1 - A match consisted of three robots on the field, each trying to score the most points. (Based on old videos, it looks like elimination rounds may have been 1v1 for at least some of these games.)
- 1999-2000: 2v2 - 1999 marked the beginning of the "Alliance Era" forcing teams to work together on the field.
- 2001: 4v0 - All four robots on the field were working together on the same alliance.
- 2002-2004: 2v2 - Direct competition during matches returned in 2002.
- 2005-Present: 3v3 - In 2005, a third team was added to each alliance.
Also, 2001 was the first year Championship was separated into divisions.

this video for 177's 10th anniversary. It gives a little insight into the 1995-2004 games.
