Been training myself to get faster at #SpotIt (otherwise known as #Dobble). Started at 390-400 seconds for a full run. Just completed a full solo run in 179 seconds. Probably impossible for me to get it under 120 seconds anytime soon but this is a big step up

I read an interesting article today by Burkard Polster about the mathematics of the game #SpotIt, and possible variations. I learned that the game "should" have 57 cards (the number of lines in the projective plane of order 7) but two were left for manufacturing and marketing reasons! https://www.maa.org/sites/default/files/pdf/horizons/PolsterApril2015.pdf
