Codenames

Two teams, two spymasters, a grid of 25 words, and pure deduction chaos. The spymaster gives one-word clues linking multiple words on the grid while desperately hoping their team doesn't pick the assassin card. It is the best party game designed this century. Codenames won the 2016 Spiel des Jahres and works brilliantly with any group size from four to ten. The Duet version for two players is equally excellent.
