Creationary by Lego
The one he chose is called Creationary, and we’ve already played it several times. Basically, you roll a die which tells you which category you’ll be building from (nature, vehicles, buildings, or things) and then you draw a card that tells you exactly what to build, but not how to build it.
For example you could roll the nature picture and then have to build a tree, or a bird, or a rhino…without any help! If you can build it good enough that someone can guess what it is, you get a point as does the guesser, and the first player to 5 wins.
Easy concept, and each game lasts about 30 minutes. Unless you build things the way I do…and then the games could last hours.
