I find it interesting as well that games are to be played until one team reaches 11 points. So, there are winners and losers. It is a competitive game.
It also sounds rather organized. As in, it is a Bethel league for Bethelites. So, again, competitive play.
Both are discouraged/forbidden by the Watchtower when it comes to the rank and file in playing organized sports. Also, what happened to the misused scripture "Bodily training is beneficial for little..." I always remember being told my free time was better used in studying or in the ministry.
