Hi Lauren, welcome to the forum. VEX rules are pretty much about what you can’t do. It says the starting height is only 15 inches and doesn’t say anything about the height after that, So you are good to go on the height.
I would have liked to have seen more diversity in the scoring, which would keep the game more interesting for teams of varying levels. As it is now, there will be a lot of haves and have nots based on who can make the triple stack.
Currently, risers in goals are all worth only 1 pt, regardless of level. Why not make second level and third level risers worth 2 pts and 3 pts, respectively, for example?
Currently only a triple stack in a completed row gives the huge bonus of 30 pts. Why not make a double stack in a completed row worth 8 or 10 pts?
I feel a few simple scoring adjustments could really help the competition be relevant for more teams and allow teams to incrementally progress towards the higher scores. Not sure if VEX ever changes the scoring rules after release, but I thought I’d try.
I also thought some 3D rows would be fun as well, but decided that might be too complicated for kids this age.
I do like the idea of a double stack getting something like 10 bonus points. So, would you score it either as a double or triple (+10 or +30), and not accumulative (+40 if a triple stack)?
Looking at the dimensions a double stack would be at 17.5", not really high or difficult. That is something most robots were able to build for Next Level using Flex. I would estimate that most teams will be able to triple stack fairly quickly.
