An electronic Monopoly accessory that adds auctions and Mortgage 'calls' to the game.The electronic play aid also keeps track of player token locations and rolls the dice. It knows which properties are bought and which ones are still available. The only things it can't keep track of are the Community Chest and Chance cards.Eight simple tunes indicate certain game actions and can get a little annoying at times (e.g.- 'I've Been Working on the Railroad' plays every time someone lands on a railroad), but overall the presentation is well done. - BoardGameGeek
