Kakegurui (2017)

The 2017 anime At this elite academy, gambling decides who rules and who serves, and students who cannot pay their debts are demeaned and forced to serve their creditors. Into that arrives Yumeko, who is not trying to escape the system: she gambles because she loves the risk itself, which makes her terrifying to everyone who plays for status. The games are inventive twists on familiar gambling, each with a cheat to uncover. The exaggerated faces and fan service will not suit everyone, but if you want the gleeful, theatrical side of the genre, start here.
