Numberphile Playing Cards
Playing cards play a role in many Numberphile videos, so we decided to make our own decks.
The cards were designed by our regular artist and animator, Pete McPartlan.
They are perfectly useful and fair as regulation playing cards - but they also have a mysterious bonus feature.
Supplies will be very limited, although we'll definitely send decks to Numberphile Patreon supporters at the end of July (2018) who are at the level "Graham's Number".
