All 100 United States senators got a special delivery in the mail this week courtesy of Cards Against Humanity co-founder Max Temkin. In an effort to send a loud and clear message about the importance of upholding a functioning democracy, U.S. senators received the new “Secret Hitler” board game.

Temkin, along with Mike Boxleiter and Tommy Maranges, sent a letter with the game explaining the premise of the game and how the senators could apply its lessons to their own life in the age of President Donald Trump. The letter reads:

Please find enclosed a copy of our new board game: Secret Hitler. Secret Hitler is a secret identy game for 5-10 players that models the rise of fascism in a democracy. To achieve his evil ends, Adolf Hitler required the cooperation of well-meanig men who hoped to appease and control the Nazis. Our game explores that relationship and highlights the difficulty of recognizing your own manipulation before it’s too late. Although our game takes place in 1933 Germany, we thought you and your staff might find our game relevant as you negotiate the balance of power with the Trump White House. Thank you for all the hard work that you do. The legislative branch plays an essential role in a stable, functioning democracy now more than ever.

The video in which the three game designers read the letter has received more than 3,800 retweets and 6,000 likes on Twitter. The game also currently appears on Amazon’s toys & games best sellers‘ list.

Secret Hitler, which received more than $1.4 million in funding through a Kickstarter campaign, is designed to be a social deduction game in which players (assigned to either be a liberal or a fascist) attempt to find and stop the Secret Hitler. According to their website, the rules of the game are simple:

The majority of players are liberals. If they can learn to trust each other, they have enough votes to control the table and win the game. But some players are fascists. They will say whatever it takes to get elected, enact their agenda, and blame others for the fallout. The liberals must work together to discover the truth before the fascists install their cold-blooded leader and win the game.

The designers hope that if nothing else, the game encourages the senators “to think long and hard about why they should or shouldn’t cooperate with President Trump and his policies.” If they consider the game’s true concept and message, they should already know how this story ends if action is not taken.
