This deceptively simple game requires a good memory and of course great concentration. Each player has one turn to select two cards. If they match then they score and are removed from the screen. The next player then tries to find a pair until all the cards are gone. The winner is the one who correctly matched the most pairs. In some card versions of this game a successful player is allowed to turn over another two cards. However, the game plays better in this 12-card version if one player cannot clear the decks so quickly. Since the game requires a pack of‘micro cards' together with the shuffle routines, these can be merged from the earlier listing. Once again you will have a very comprehensive program which makes full use of the memory, without having to type in more than is necessary. Here is a money raising tip. Those readers who are involved in raising cash for charities or school funds may like to consider how the micro can help. Concentration could be used as a fund raiser, just as many other programs featured in the book can. Simply set up your computer and charge visitors for the privilege of pressing the buttons! |
