This Week's Exciting Puzzle: the Birthday Party

This puzzle appeared in Volume 80, Issue 5 (June 30, 1999) of mathNEWS.

Hey, my birthday's coming up (well, by now it's already happened), and I gathered a bunch of friends (where a bunch is six) over to my place to help me celebrate it. It was a potluck dinner, followed by cake and ice cream (each person had a different flavour). Then we discussed what type of activity would best celebrate my birthday (for example, going to Sauble Beach and playing volleyball there). Each guest also happened to bring a gift for me (being my birthday and all go figure).

What you need to do, to help me celebrate my birthday, is figure out who each person is, what food and gifts they brought, what activity they suggested, the order they arrived, and the flavour of their favourite ice cream. Now go ahead and PARTY!!

Important notice: since my birthday lasts a whole week (in my world), we actually did all of these activities - one each day - including what I chose to do: go play pool at the Bomber tonight with all my friends (see ya there!).


  1. The six people are: Edna; the person who brought dinner rolls; the person who suggested a game of beach volleyball; the guy who gave me a sundress; the person who arrived second; and the person who prefers tiger tail ice cream.
  2. The person who suggested going to watch the Benson & Hedges fireworks show arrived immediately before the person who gave me scented candles, who arrived before the person who brought homemade coleslaw
  3. The person who loves strawberry ice cream (who did not give me the book) arrived immediately before the person who suggested the great card game of Mao, and sometime after the person who gave me the dress.
  4. The person who brought cream soda (not Trish) suggested a theatre trip to see One Bad Apple, but did not give me the gift certificates.
  5. Miss Smith, who suggested dancing at Whiskey Saigon, was not the person who gave me a goldfish, and does not like vanilla ice cream (it's too plain!).
  6. The guy who gave me the Great Big Sea CD (who doesn't like peanut butter ice cream) arrived last. Apparently there was a lineup at the store.
  7. The girl who prefers heavenly hash ice cream made a scrumptious vegetarian lasagna (and did not give me the book).
  8. Stan (who did not suggest the fireworks) arrived before the person who like vanilla ice cream best, and after the person who brought the macaroni salad (not Edna).
  9. The person who brought the mashed potato salad (who did not give me the movie gift certificates) arrived after the person who likes cookie dough ice cream (who is not Mike).
  10. The person who suggested going swimming at the wave pool in Bingeman's (who loves strawberry ice cream) arrived after Jean (who did not bring the pop), and before the person who brought potato salad.
  11. Mr Jones, who brought the macaroni salad, gave me neither the goldfish nor the gift certificates, and did not suggest a game of cards.
  12. Neither the person who brought potato salad nor the person who gave me an Agatha Christie novel, wanted to go swimming.
  13. The person who brought the pop (who did not give me the goldfish) answered the door when the person who loves tiger tail ice cream arrived. Neither of them is Bill (who did not bring cole slaw).
  14. The person who wanted to go swimming (who did not bring the cole slaw) arrived after the person who gave me the book (not Bill), who arrived immediately after the person who brought the lasagna.
  15. The person who suggested playing volleyball (not Mike) does not like heavenly hash ice cream.
  16. Trish does not like heavenly hash ice cream, and was not the person who gave me the gift certificates (who did not suggest dancing).
  17. Edna (who does not like peanut butter) does not want to go dancing, and arrived after the person who gave me the candles.
  18. The person who arrived second did not suggest the theatre trip, and did not give me the gift certificates.
  19. The person who suggested a game of cards (not Stan) did not bring potato salad.
