Schadenfreude is a trick-taking card game for three to five players by ctr, published by Studio Turbine in Japan in 2020. You must follow suit, but the second-highest card of the led suit takes the trick, so the highest card loses. The winner keeps their own card plus every off-suit card in the trick, and a card's number is its point value, from −3 to 9.
Two wild cards change everything: the 10 is always highest and can never win, so it forces the real high card to take the trick; the 0 is the cheapest way in. Your score pile may hold only one card of each value, and a duplicate cancels both. After each round the points go onto a 0–40 track: whoever ends closest to 40 without passing it wins, and a tie for the top wins nothing.
