Lovecraft Letter is a card game that combines theLove Lettersystem with the world of H.P. Lovecraft. In addition to the standard sixteen cards in theLove Lettergame are new versions of the cards that include special "insanity" powers. If you have one of these cards in your discard pile, then you are insane (at least for the current round) and on future turns can play insanity cards for their regular power or their special power, giving you more options during play. The risk, however, is that you must undergo a sanity check at the start of each of your turns, drawing as many cards from the deck as the number of insanity cards in front of you; draw one or more insanity cards, and you're out for the round.
If you win the game, whether by being the last person standing or the player with the highest single card after the deck runs out, you win a token colored to reflect whether you were sane or insane. Win enough tokens of the right type, and you win the game.
