It is the reworked version of the popular BBC TV series, Mastermind, tweaked to include families as participants.
In the first round, the smallest member of each family has to give answers of General Knowledge questions while in Second round each family has to choose a special subject the contestants can pass if they do not know the answer.
After the two minutes is up a buzzer is sounded, which is made up of four beeps; if a question is being read (or has just been read), then the contestant is given a short period of time to answer.
In the final round, again, General Knowledge questions are asked but this time with negative marking.
After each round the scores of the contestant family are announced.
