This second collection of interesting mathematical puzzles continues the tribute to Martin Gardner, who has provided us with original puzzles and puzzling stories ever since he created and produced the "Mathematical Games" column in Scientific American. The international community of puzzle enthusiasts has gathered once again to celebrate Martin Gardner's continued contribution and, most fittingly, has done so in kind, by providing new challenges to our inquiring minds. We proudly present this collection to the mathemagicians of the world for their enjoyment, as a playful provocation.
" "". . . even well-known puzzles retain their power, as was made clear again and again last month at the seventh ""Gathering for Gardner."" These conferences of mathematicians, puzzlers, game-players and magicians at the Ritz-Carlton here began as personal tributes to Martin Gardner, Scientific American's legendary Mathematical Games columnist, and now take place without the master's presence (he is 91). During four days of talks and tricks, the oldest puzzles mixed freely with the newest."" -Edward Rothstein, The New York Times , April 2006
""This presents an incredible range of beautiful material, witty ideas, tantalising puzzles, intriguing problems, and surprising ingenious solutions. Anyone interested in mind-boggling problems will find plenty to interest them here."" -EMS Newsletter, November 2003"
