There are a few games around that involve heraldry.
Sometimes a "game" can be a task that a few bored heralds may assign to themselves. I was involved with one of these, where six of us, having been left pretty much unsupervised, tried to create a coat of arms consisting of a field and a single standard heraldic charge that everyone who saw it would say was "too complex."
I think we may have succeeded. This is what we came up with:
The blazon is: Gyronny [of eight] lozengy gules and or, and vair, a mascle throughout counterchanged.
Other heraldic games try to combine some fun with education, like the "Heraldic Bingo" game that can be purchased from http://www.appletonstudios.com/BooksandGames.htm
Well, the other day over on Reddit, I saw a new heraldic variant of an old game that someone has come up with: Heraldic Telephone. The way it is played is described as:
All the players are organized into a list, and the first person in the list is given a coat of arms that they need to blazon. They send their blazon to the second person in the list, who proceeds to draw a coat of arms using only that blazon. They then send their coat of arms to the next person in sequence and this continues until the final player and all the coats of arms and blazons are revealed!
(If you want to see something of the way it can go, you can see the results of a round played in April of this year at https://old.reddit.com/r/heraldry/comments/8du5k8/april_2018_telephone_game_results/)
What an intriguing concept! And it's the kind of thing that could be played on-line or in person with friends with a few pieces of paper. (Well, you'd also want something to write with, and colored pencils or Crayola markers or something similar to draw the coat[s] with.)
What an interesting idea for the next time you're sitting around with some other heraldry enthusiasts and want a fun way to pass the time.
Just a thought.
