Crazy Eights uses ordinary playing cards, but published versions differ even on drawing. We therefore identify Bicycle’s rules as our baseline and separate them from alternatives. Mau-Mau, Switch and UNO actions do not automatically apply.
In this guide
The Bicycle baseline in brief
Bicycle uses 52 cards and five-card hands. Match suit or rank. Any eight chooses a suit; the next play must match that suit or be another eight. Without a play, draw until a card can be played or the stock runs out. Remaining values: eight 50, faces and ten 10, ace 1, others face value. An initial eight is buried and replaced.

A rank match is not a declaration
Our example begins with spades queen. Hearts queen matches rank; the new top really is hearts queen. Spades 5 instead matches suit and keeps spades active. Diamonds 6 matches neither. Choosing between two legal connections changes the options that follow.
Position as text
Top: spades queen. Hand from left: hearts queen, spades 5, diamonds 6, clubs 8. Legal: 1, 2, 4.
After an eight, the declared suit controls
A printed hearts 8 with spades declared does not require hearts. Spades is active for the next player. Hearts queen therefore does not connect; spades 4 or another eight does. The eight’s rank does not give every other card an extra matching route: it is the wild function itself.
Do not import penalty cards silently
In this simple comparison a two does not automatically mean draw two, and a queen does not automatically skip. Adding such effects creates a different agreement. This is where links to Switch and Mau-Mau become useful: the same matching idea can change the state in different ways.
