Mobius Posted September 14, 2005 Share Posted September 14, 2005 I'm just wondering if anyone knows any decent books (not magazines) for puzzles. I am not interested in sudoku, word searches, crosswords etc... I prefer maths, geometry, logic and science puzzles. Especially ones that are challenging (but not impossible i.e. PhD standard!!!!) Websites are good, but I'd prefer books... Thanks Link to comment Share on other sites More sharing options...
DQW Posted September 15, 2005 Share Posted September 15, 2005 One of my favorites was Martin Gardner's Science Fiction Puzzles. There's some really neat puzzles at rec-puzzles.org Link to comment Share on other sites More sharing options...
