You can learn more about the Nuclear War card game at Flying Buffalo’s Nuclear War section: http://www.flyingbuffalo.com/nucwar.htm. You can also read about it on Wikipedia: https://en.wikipedia.org/wiki/Nuclear_War_(card_game). I call it a soda and pretzels game, some would substitute an alcoholic beverage for soda, but I think soda and pretzels fits. It’s a game that can be played by family or with friends.
If you have never played it, there tends to be many games where nobody wins, which is a reasonable expectation in a true nuclear war real-life scenario. Some who have never played the game claim it glorifies nuclear war. All it takes is playing a game or two to show how wrong that assessment will be. Out of hundreds of games I have played, it’s rare that anybody wins and extremely common that everybody dies.
Here’s its rating on https://boardgamegeek.com/boardgame/713/nuclear-war. It’s 6.2 (10 point scale) with 2,670 reviews and 997 comments.
It spawned several expansion sets: Nuclear Escalation, Nuclear Proliferation, Weapons of Mass Destruction (all but the last one is available although they hope to do a new printing of WMD sometime in the near future – you may find a copy of it online onAmazon, EBay, etc.).
I give it 5 stars, using 5 🌟 scale. High replay factor.
