Puzzlers' Tribute

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.
