Last week, I bought on amazon.com the Jeopardy! game tin by Igloo Books. The biggest disappointment is that it only has enough material for TWO complete games! Although there are 12 different FJ! categories/clues.
When they say that it has "56 prize cards," they mean that there are 8 sets of seven money value cards. Six cards in each set have the clue value on one side and the Jeopardy logo on the other. The seventh one in each set says "Daily Double," on the reverse side. As a bit of a spoiler, this means that the "Daily Doubles," for DJ! would each be hidden behind a different value (ex. $2,000 in one category and $1,200 in a different one).
Nice collectible tin, but not a great game (the Hasbro/Parker Bros. version from 1999 is still the best).
