primePrime, by JL Fletcher and Brett Pelham, published by sggc Mama Luke Playing Cards, is a quick card game.

The deck has prime numbers 2 – 17 and the letters P, R, I, M, and E. You start with 7 face down cards, of which you can look at 4 of them. Each round, pick a card, discard a card, and turn one card in your tableau face up. When all of your cards are face up, score for any non-duplicated cards. The letter cards are worth 0 in the basic game, and have special abilities in the advanced game.
