The game consists of a deck of 42 cards: 8 'Radar Image', 32 'Monster Parts', and 2 Wild cards. A game board is also included which has spaces for up to four 'radar' screens'.The entire deck is shuffled and five to ten cards are dealt to each player (depending on how many are playing).On each turn a player draws one card and then may play one card to each active Radar screen on the board. If he holds a 'Radar Image' and an empty screen exists it must be played (this is the only compulsory play). Monster Parts may only be played on areas that have an Image.The first person to get rid of his hand of cards wins.A good card matching game for Ages 7 - 12... not much more. - BoardGameGeek
