What we measured
This is four of a kind appearing among the five community cards, so every player still in the hand plays the same quads and the winner is decided by the fifth 'kicker' card (or it chops). It needs all four cards of a single rank plus any fifth card on the board.
How it was calculated
Exact combinatorics: 13 ranks x 48 possible fifth cards = 624 qualifying boards out of C(52,5) = 2,598,960.

Frequently asked questions
How often does the board make quads?+
About 0.024% of hands — roughly 1 in 4,165 — the five community cards themselves show four of a kind. Everyone shares them, so the best fifth card wins.
Who wins when there are quads on the board?+
Whoever holds the highest fifth card. If the board is, say, four aces plus a nine, a player holding a king plays aces-with-a-king kicker and beats someone playing the nine. If no one can beat the board's own kicker, the pot is split.
