From the post:
In Concept, the goal is for players to guess a word through a series of associated icons. One player chooses a word and they must get the other players to guess it. That player can’t use any verbal clues or gestures; instead they must rely on a game board full of icons. By placing clue tokens around the board, they will try and lead the players to the correct answer. Guess an answer correctly and you both win victory points (technically, more on that later).
