Exhibit
Closest calls.
The archive checks every full 52-card order against every other and has never found two the same. It also notices how close two shuffles came. This room holds every pair whose opening cards, dealt in order, matched for 6 cards or more. The rest of each pair is unrelated.
What is ranked
Shared opening depth: the number of cards, counted from the top of the deck, that two shuffles dealt in exactly the same order before they diverged. A depth of six means the first six cards match and the seventh does not.
How rare
Two random decks open with the same 6 cards in the same order about once in 14,658,134,400 pairs. Across millions of shuffles, that many pairs exist, which is why this room is not empty.
The record
9 cards
The deepest two shuffles have ever come to matching is 9 opening cards in the same order, set on July 27, 2025 by shuffles #4,641,857 and #7,517,980. 6,911 pairs are on record.

Each additional card of agreement is about 45 times rarer than the one before it (52 minus the depth, exactly). The record moving by one is the kind of event this archive exists to notice. How the check works, and why it never fetches a full deck, is on the methodology page.
