The best boardgame that I ever played was in the 80's. I borrowed a game from a toy library. It was like a whodunnit game [ No it was not any form of cluedo] where you were given a crime scene and clues and you had 3 guesses. There was an electronic device that you pushed for guesses. The cases were clever and the criminal wasn't often who you suspected.
I have forgotten what the board game was called. It was American.
of course chess is the best boardgame.
but I think other boardgames are great.
Games I can recommend:
Settlers of Catan
Backgammon
Blokus
Monopoly
I am a big fan of boardgames
