Cambridge Polo

Those playing BFF please take note:

Mallet heads in the “European cheater” style are banned from this tournament.

It also seems they have not gone back on their rules of scoring:

To score you may put the ball in the goal anyway you like. eg. Shuffle/Shaft/Shot/Scoop/Ball Joint/wheel/header. Anything that crosses the line is a goal (with the exception of the use of hands and feet). This includes a ball stuck in one’s spokes (riding into goal).
