The Game: Extreme — overview by designer Steffen Benndorf at SPIEL 2016

About The Game: Extreme, from BoardGameGeek:

The Game: Extreme features cooperative gameplay similar to The Game, with all players working together to discard all of the cards in the deck onto four discard piles. What's new in The Game: Extreme are 28 instructions on the cards themselves that affect the rules of the game while they're in play, increasing the difficulty of completing the game - or rather, The Game.
