Hanabi, was also one of the fiddliest. If you don't own Hanabi, well, firstly, why not? It's 8 bucks!!!! Secondly, you might not have played it so you won't know how hard it is to not reveal your cards when holding them or picking them up as you always have to face them away from yourself. Well, thanks to the immense and well-deserved popularity of the game, Abacus Spiele released a giant edition with card stands and nicer pieces and a deluxe collector's edition with Mahjong-style tiles and wooden box to hold everything.
BoardGameBliss (wonderful store by the way with some really obscure European stuff like this and a very friendly, generous owner). And OF COURSE, I couldn't help myself!
