Have you noticed that these dice on this game of Shut the box are a bit dodgy. On most dice the opposite sides add up to 7. 6 & 1, 5 & 2, 4 & 3. Here we see them on adjacent sides.
Apparently this game is played in British pubs. I think it’s fair to say that I’ve visited several bars to swig beer and have seen this game precisely zero times.
