When was the Frustration board game invented?

The Frustration board game wasn't invented. It's a variation of a much older game called "Trouble" which was invented by Milton Bradley in 1965.

The name "Frustration" is commonly used to describe a specific version of the game where players can *knock other players' pieces back to the start*, adding a more competitive and frustrating element. However, this name isn't officially recognized by the game manufacturers.

So, while there's no specific invention date for "Frustration", the game's origins lie in the 1965 invention of Trouble by Milton Bradley.
