The game of Wordle seems to be a fad now.
As for little games of strategy, I often think that we should make sorting one's recycling into a game. Figuring out what goes where, what types of plastic go into different bins so less types of plastics are mixed. Might sound too complicated, but it could be fun, like other games.
We could even keep score among folks and buildings that have recycling bins. Who can create the cleanest recycling stream. Who can create the stream that is most useful for industry as a recycled resource.
