Castles of Mad King Ludwig Expansions 2nd Edition by Bezier Games, Strategy Board Game

It adds quite a bit to the base game like secret passages, moats, etc...It may be a LITTLE bit pricey for what you get, but it does expand the original game by quite a bit! And, the designers had the forethought to design the base game box to include enough space for the expansion trays.*Please note, if you buy the second edition base game and this expansion set, then you do NOT need the "Secrets" expansion set, this pretty much includes all of that already, and the artwork matches the 2nd edition base game, too.

If you like puzzly games you will love this. We also bought the expansion which is great if you are going to play it more than a little.

If you have an "old" copy of the original game, be warned that this is not easily compatible. Most drastically the card sizes are different. I'm not impressed with the company requiring people to buy a second copy of the original game to be able to use the expansion. I wish I had realized before I opened the game, as I would return it. It's too bad because the expansions are really fun!
