VEX Change up is the 2020 to 2021 VEX game. This game uses 6.3 in hard plastic balls that have to be scored in goals that have an inner diameter or 7.3 in. I personally find this years game to be much easier and simpler than the previous years due to the only 1 scoring method. I believe this year will employ lots of defense to ruin peoples ball stacks and take away goal ownership. The goal are also only 19 in high so there is only a 1 in gap between the maximum height of the robot and the top of the goal. The goals also have green back boards on them for vision finding similar to the flags in turning point. This can give teams an advantage on lining up to dispense balls when using the vex vision sensor. The only goal to not have a backer is the central goal which also has all of its posts unlike the goals in the corners and on the edges.
Another interesting fact about this years game is the emphasis on win points earned when a alliance wins a match. This year REC has also added that is you have complete ownership of your home row during autonomous then you get an extra win point. This generates a maximum of 3 win points for the alliance per match.
Similar to last year there is also no expansion limit possibly allowing "wallbots" to become a big defensive player. Similarly teams will also have a preload for each robot at the beginning of the match.
