This is the two book player. Many versions were made. The first was the best. The basic game is simple. think of a move, tell the other player the page at the bottom, he tells you his. go to that page, look at your move, and the third page is the result. first player to be hit 6 points losses. in an era of compurter games Ace of Aces is now boring to most kids i think. however it would be a great car game,and the advanced game is complex with altitudes, crashes, etc. i am still amazed at the inventor's idea of this game. can play with 4 books and form teams.
