Ndr: When I was still in school and there were no phones to do anything at a boring class, we came up with an interesting game called “Warlords.”
Both participants sit for one piece, put their hands on it, loosening their elbows to the sides. Then they try to clash with each other from the batch, use the elbows for this and thus "draw" a place behind the batch. The teacher who is thrown out of class loses.)
