The Velleman MK133 operates on a 9V battery (not included). This kit allows four players to compete to answer the quizmaster’s question. An LED will notify the quizmaster who was the first player to press their button and they will be able to answer the question asked. An eight player game can be played by connecting a second MK133 with a 3 wire connection (wires not included). The second MK133 will not need an additional 9V battery to operate.
