American architect Bryan Berg has succeeded himself as the world record holder in number of cards stacked. He built a replica of the Venetian resort in Macau inside the hotel itself. The creation is composed of 218,792 cards (4,051 decks) with no glue or other aids to hold them together. The feat took Berg 44 days. The hotel replica stands almost ten feet tall and is 33 feet long!

'This has been the most ambitious project I have undertaken to date,' Berg said.
'It's really like a real construction project because you have to engineer every single adjacency and every support that's supporting everything above,' he added.
'I was inspired to stack cards by my card-playing grandfather; maybe I can inspire some visitors at The Venetian Macao to try their hand at building their own structures.
'There couldn’t be a more fitting place to build the world’s largest house of cards than at the world’s largest resort hotel,” he added.
