Secret Door is a fun memory-type game with a detective, spooky old mansion theme. My kids really like this one and it's been a well loved over the last couple years. Because of the simple rules, t's one of my favorite Family Pasttimes games for the younger set.
I bought this game when my kids were 3 and 6. Both of them loved the game. After a year or so, we lost some of the pieces and they still wanted to play it - So, I bought it again. It's a quick and easy game - kindof like a matching game, but it's cool when you work together as a team and you come up with funny or unique ways to remember what item is in each area of the board.
