1 cards
Yes or No spread
The Yes or No spread uses 1 card in fixed positions — the answer. A single card read for direction rather than detail. Use it sparingly. A yes-or-no question usually hides a better question underneath.
How many ways it can fall
156 possible yes or no spreads
1 position drawn without replacement from 78 cards, each landing upright or reversed: 78 × 2. Small enough that repeats do happen — worth knowing before reading one as a sign.
Reversals double the count at every position. Readers who ignore them are working with 78 instead — still plenty, but a different deck of possibilities.

Use it sparingly. A yes-or-no question usually hides a better question underneath.
How to read it
Lay the cards face down in order, then turn them one at a time and say what you see before reaching for a meaning. The image comes first; the book comes second.
Read positions against each other rather than in isolation. In a three-card spread the interesting information is usually in the gap between the first and the third — what has to change for one to become the other.
Reversals are optional. Decide before you shuffle, not when an unwelcome card appears.
