This is a bit of a #blindfolded-speed-cubing crossover.

The challenge is to memorize a deck of cards, blindfold yourself, and bring the same deck of cards back into sorted order. So unlike in regular speed cards where youâd bring a second deck into the same order of the deck youâve memorized, you just work with one single deck of cards.

The time starts when you pick up the deck and you are not allowed to move any cards around during memorization. Once you put on the blindfold and moved the first card, you can only take it off again after youâve completed the attempt. If you want to continue memorization and havenât moved a card yet, you can take the blindfold off again.

The time to solve is the total time (memorization and sorting). An ordered deck looks like youâd normally use it for recall in regular speed cards, so if your order is A-K for spades, hearts, clubs, and diamonds then you bring the deck into that order.

You are allowed to use the table, so if you want to create a pile for each suit and then pick it up again or swap cards by putting a porting of the deck on the table and picking it up again after the swap, itâs all good. In the end you have to lay down just one pile of cards and take off your blindfold to stop the time.
