T8

From BoardGameGeek:

T8 is a trick-taking card game for four players. The game is based around having eight suits, and eight cards per suit. The twist is that players can't follow suits previously played, and they play two cards per per turn into the trick. There is a new scoring mechanic built around the two-card-per-trick mechanic: the lower of the two cards played scores positive points, but any cards lower than that (from the other players) score negative points. There is also a solo mode, in which players seek to give three automated opponents negative scores while earning a positive score themselves. The game was designed to be given to attendees at the convention T8 in January 2023. -description from the designer
