#ALSO huge tangent but is pulling coloured stones out a bag even fair?

[velaraffricate]

one thing ive been wanting to do for my conworld is invent some sports. came up with this idea yesterday:

there's typically 3 or 4 evenly spaced apart (5-20m away from each other) trees, but can be more depending on field and team size

trees thickness can vary but are usually somewhat thick, can also be replaced by movable poles so field size can be adjusted depending on how many players there are

space in middle is clear, ground is usually just dirt

1-3 players are assigned to each tree

each player/team has to hit the opponent team's tree and avoid their own tree being hit

hitting a tree gets you a point, getting hit loses a point

once a certain number of points, typically ranging between 5 and 10, is reached by one team, they win

trees and players are marked with colourful cloths for easy identification

ball is usually made from leather stuffed with wool or feathers

players are only allowed to touch the ball with their feet and knees, but not their hands or other body parts

if ball is touched with forbidden body part, that team loses the ball, and whichever enemy's tree they were closest to, that team gets the ball

shoving other players or being otherwise overly aggressive isn't tolerated and results in point loss or disqualification

if tree is hit, that tree's team gets the ball. one player stands at the base of their tree and kicks it to a teammate, or if only one player, they just start playing again from the tree

who has the ball first is decided by random chance, like pulling coloured stones out of a bag, or often if there's only one player per tree, who the youngest person is

the ball can't go outside the field. if that happens, whichever team's tree it was closest to when it exited, that team gets the ball barring the team that kicked the ball out

obviously inspired a lot by soccer in some parts but still different enough for my taste. am curious if something like this already exists, i did do a bit of research into ancient sports but really only took a cursory look and didn't find anything quite like this
