Q: I have an old game called “Bonanza” that has been in my family for many years. It was made by Parker Brothers. We have the original mat, chips, and cardboard instructions that list copyright dates 1936, 1941, 1942, and 1946. Can you tell me anything about it?

A: The game Bonanza is a variation of Michigan rummy. The copyright dates suggest that the game was introduced in 1936. Parker Brothers made several versions of Bonanza, including a 1964 version featuring the Cartwrights from the TV show “Bonanza,” which ran from 1959 to 1973. The 1955 and 1964 versions often show up online and sell for $15 to $50. Your game board is not the same as the 1955 board, so your game must have been made after 1946 but before 1955.
