How the cast is built, what the six lines mean, and how to ask a question that gives the reading something to work with.
How an I Ching reading works
The I Ching, or Book of Changes, is a traditional Chinese system that uses a six-line figure, called a hexagram, as a framework for thinking about a question or a situation. In the three-coin method you cast six lines from the bottom up. Three coins are tossed for each line: their total gives the line a value between six and nine, which decides whether the line is solid or broken and whether it is changing. The lines you cast form the primary hexagram. Any changing lines are then flipped, which produces a second, resulting hexagram. Reading the two together is the traditional way of seeing both the situation as it stands and the direction it is moving in.
What the six lines mean
A hexagram is read from the bottom line upward. The lower three lines form the lower trigram and the upper three form the upper trigram, and the pairing of those two trigrams is what defines the hexagram. Position matters as much as the shape: the bottom line is the earliest and most private part of a situation, while the top line is the most exposed and furthest along. A line is either solid (yang) or broken (yin), and it is either stable or changing. Changing lines are old lines: an old yang line is changing into yin, and an old yin line is changing into yang. Positions with a changing line are the places where the situation is least settled.
Primary and changing hexagrams
The primary hexagram describes the situation as it currently stands. The resulting hexagram describes where the changing lines are heading, so it is only meaningful when at least one line is changing. If no line is changing, there is no resulting hexagram: the reading stays with the primary hexagram and describes a situation that is stable in form. This page shows both when they apply, and marks exactly which line positions are changing so you can see where the movement is concentrated.
How to ask a useful question
A good question is specific, open, and about something you can actually act on: a decision you are weighing, a relationship you are part of, or a situation you are trying to understand. Questions starting with how or what tend to work better than questions asking for a verdict, because they leave room for an answer that describes the situation rather than announcing an outcome. Ask one question at a time. Before you cast, take a moment to settle on the question, then keep it in mind while you press the button: the value of the reading comes largely from what you notice while thinking about it.
I Ching vs BaZi
The two traditions answer different questions. The I Ching is consulted about a specific question or situation in the present: you cast, and the reading applies to what you asked. BaZi, also called Four Pillars, works from birth information instead, and describes longer-term structural patterns rather than a single situation. Neither replaces the other, and neither is a scientific instrument. If you want context on a decision you are facing, the I Ching is the closer fit; if you want a wider view of recurring patterns in your life, BaZi is the closer fit.
Frequently asked questions
What is the I Ching?
The I Ching, or Book of Changes, is a traditional Chinese text and divination system built around sixty-four six-line figures called hexagrams. It is used as a framework for reflection on a question or situation.
How does the three-coin cast work?
Three coins are tossed for each of the six lines. The total of the three coins gives the line a value from six to nine, which determines whether the line is solid or broken and whether it is changing. Lines are cast from the bottom up.
Do I need an account or any personal details?
No. There is no sign-up, and the reading does not need your birth information. You enter a question, cast, and read the result in the page.
Is my question stored or sent anywhere?
No. Your question stays in your browser while you use the page. It is not saved, not sent to an API, and not included in analytics.
Does this predict what will happen?
No. The result is a traditional framework for reflection, offered to help you think about a situation more clearly. It is not a scientific method, and it does not promise outcomes.
Why is there no deep interpretation yet?
The free reading is deliberately self-contained and runs entirely in your browser, with no AI involved. A deeper written interpretation is a possible later addition, not part of this version.
The I Ching speaks to one question at a time. A BaZi chart works from your birth information instead, and describes longer-term patterns.
