The Mind Extreme offers a more complex challenge as now instead of a deck of cards from 1-100, you have two decks each numbered 1-50. Now you'll have two discard piles in play, with cards from one deck needing to be played in ascending order and cards from the other being played in descending order. What's more, some levels must be played blind — that is, with the cards discarded face down so that no one sees what you've played. Can all players get in the right groove and discard everything in the proper order?
