It is simple to learn, and is one of those games that the more people you have playing, the better it gets! We have added an extra deck of UNO cards, even when it is only five or six players just to keep it interesting!
The best part is that you can play with players as young as 5, and as old as 105! Mattel recommends the game for ages 7 and up, but we have included younger kids who were able to grasp the game quite readily !
It is a hit during game night, fun to play at get togethers, and is easy to take along and play at the beach, or any other time and place where you are looking for something easy to play, that is suitable for large groups of people various ages!
I have spent time living in close quarters with new immigrants, and there is often language and cultural barriers that limit the level, and quality of things you can all do together, but UNO is one of those games that is easy to enjoy across language and cultural barriers, to bring people together for a fun time!
The things that *might* give you a hang up; The base set of the game only accommodates 4 players, If you have a larger family than that... like we do, you need the *extension* set also, which makes it cost a bit more to play.
That said, the game is totally worth it. My kids have learned so much about planning, about how societies develop, what sorts of things are necessary and the time it takes to grow a civilization. The base game is actually very simple in concept, but there's so much to do! If you wish, there are "expansion" sets. These are not different versions of the original game, but ways to introduce more factors into your game - like seafaring voyages and exploration. Sometimes I cannot even keep up with what's from the original game and what's new, but the instruction booklets are really helpful and once you jump in and play, you are on a roll.
