How to Cast the I-Ching with Coins
A 15-minute step-by-step guide to consulting the I-Ching using the three-coin method — the most accessible way to work with the ancient Chinese Book of Changes.
The I-Ching, or Book of Changes, is a Chinese divination text that has guided kings, sages, and seekers for more than three thousand years. At its heart sits a system of 64 hexagrams — six-line figures built from broken (yin) and unbroken (yang) lines — each describing a particular pattern of change at work in a situation. You ask a sincere question, cast the coins, and the hexagram you build becomes a mirror for what is moving beneath the surface of your life.
The three-coin method is the most common way to consult the I-Ching today. It is faster than the traditional yarrow stalk ritual but still gives you the full range of stable and changing lines, which is what makes the reading dynamic rather than static. Three coins, six tosses, and a translation to read from — that is the entire setup.
This guide is for anyone who wants to begin a personal practice with the I-Ching: people drawn to Taoist philosophy, students of divination, journal-keepers looking for a contemplative tool, and anyone facing a question that needs more than a yes or no answer.
What You Need
- Three identical coins (Chinese coins are traditional, but three pennies or any matched set work)
- An I-Ching translation — the Wilhelm-Baynes edition is the classic, Hua-Ching Ni's version offers a Taoist lens
- A piece of paper or a journal
- A pen
Before You Start
No prior experience with divination is required, but the I-Ching responds best to a settled mind. Take a few quiet breaths before you begin and have your question already shaped before you pick up the coins. Skim the introduction of your translation once before your first reading so the language of yin, yang, and changing lines feels familiar.
Steps
- 1 Step 01
Sit quietly with your three coins
Find a flat surface and a few minutes of uninterrupted time. Place the three coins in your dominant hand. Heads will count as 3, tails will count as 2 — keep that assignment consistent for every toss in the reading.
Tip: Traditional Chinese coins have a square hole in the center; the inscribed side is yang (heads, value 3). If you are using regular coins, just decide which side is heads before you start. - 2 Step 02
Form a clear, sincere question
The I-Ching answers questions about pattern and movement, not requests for predictions. Phrase your question as 'What do I need to understand about...' or 'How should I approach...' rather than 'Will X happen?' A sincere question is one you genuinely do not know the answer to.
Tip: Write the question down before you cast. This anchors the reading and gives you something concrete to return to when you interpret the hexagram. - 3 Step 03
Hold the coins and focus on the question
Cup the three coins between your palms. Bring your attention to your question and let everything else fall away for a moment. There is no required ritual here — what matters is that you are present with what you are asking.
- 4 Step 04
Drop the coins gently on a flat surface
Open your hands and let the coins fall onto the table or the floor in front of you. They should land flat enough to read clearly. If one rolls off the surface or lands on its edge, gather all three and toss again.
- 5 Step 05
Record the value and draw the first line
Add the values of the three coins. Heads = 3, tails = 2. The total will be 6, 7, 8, or 9. Then draw the corresponding line at the BOTTOM of your page: 6 is a broken line with an X or circle through it (old yin, changing), 7 is a solid line (young yang, stable), 8 is a broken line (young yin, stable), 9 is a solid line with an X or circle (old yang, changing).
Tip: Hexagrams are always built from the bottom up. Line 1 is the bottom line, line 6 is the top. This is the single most common place beginners go wrong. - 6 Step 06
Repeat five more times, building upward
Gather the coins, toss again, and draw line 2 directly above line 1. Continue until you have cast the coins six times in total and stacked six lines on top of each other. Each toss is independent — do not let the previous result influence how you handle the next one.
- 7 Step 07
Identify your primary hexagram
You now have a six-line figure. This is your primary hexagram — the situation as it stands right now. Use the lookup chart in your I-Ching translation (usually printed on the inside cover) to find the hexagram number. The lower trigram is lines 1-3, the upper trigram is lines 4-6.
- 8 Step 08
Build the second hexagram from any changing lines
If any of your lines were 6s or 9s, those are 'moving lines' — they are in the process of transforming. Draw a second hexagram next to the first. Keep all the stable lines as they are, but flip the changing ones: a 6 (old yin) becomes a young yang (solid line), and a 9 (old yang) becomes a young yin (broken line). This second hexagram shows what the situation is moving toward.
- 9 Step 09
Read the text in this order
Open your translation to the primary hexagram and read the Judgment and Image. Then read the text for each changing line, in order from line 1 upward. Finally, read the Judgment and Image of the second hexagram. The primary hexagram is where you are; the changing lines are the active edges; the second hexagram is the direction of movement.
- 10 Step 10
Journal the question, hexagrams, and your reflection
Write down the date, your question, both hexagrams (with their numbers and names), and your initial reflection. The I-Ching is poetic and often becomes clearer over hours or days, so leave space to come back to the entry. A journal also lets you track which readings prove accurate over time, which is the best way to deepen trust in the practice.
Tip: Do not throw the page away even if the reading feels confusing. The meaning often surfaces a week later when the situation has unfolded a little further.
Expected Results
A complete I-Ching reading takes most people about 15 minutes once they are familiar with the process. You will end with a primary hexagram, possibly a second hexagram, and a passage of text to sit with. The first few readings often feel obscure — the language is image-heavy and ancient — but as you build a journal of past readings, patterns begin to emerge. Many long-term practitioners describe the I-Ching less as a fortune-telling tool and more as a mirror that shows them parts of a situation they had not yet articulated.
Common Mistakes
- Building the hexagram from top to bottom — always work upward, with line 1 at the bottom and line 6 at the top.
- Skipping the changing lines — the moving line text is often the most important part of the reading and tells you exactly where the energy is shifting.
- Asking yes-or-no questions — the I-Ching is built for guidance and pattern recognition, not predictions. Reframe binary questions into open ones.
- Asking the same question over and over hoping for a different answer — if you do not like the first reading, sit with it instead of recasting.
- Using a poor or paraphrased translation — the Wilhelm-Baynes (with the Cary Baynes English) is the classic, and Hua-Ching Ni's version is excellent for a Taoist reading. Avoid stripped-down 'modern' rewrites for serious practice.
Troubleshooting
- I had no changing lines
- That is a complete reading on its own. With no moving lines, you only have a primary hexagram — read the Judgment and Image and skip straight to interpretation. The situation is stable for now.
- I had four or more changing lines and feel overwhelmed
- When most of the lines are moving, the reading is about wholesale transformation. Step back from individual line texts and focus on the relationship between the primary and second hexagrams as a single picture of change. Ask: what is ending, what is beginning?
- The reading feels obscure or contradictory
- The I-Ching speaks in images and metaphors, not in plain advice. Write the reading down, walk away from it for a day, and come back. Almost every reading clarifies once the situation moves forward a little — the text was waiting for context you did not yet have.
Variations
The yarrow stalk method uses 50 dried yarrow stalks and a sorting ritual that takes about 20 minutes per line — it is the original method and produces a different probability distribution for changing lines, which many traditional practitioners consider more accurate. The three-coin method shown here is the most common today and balances speed with depth. A six-coin variation lets you cast all six lines in one throw but loses the meditative rhythm of casting line by line. Digital and app-based generators are convenient but tend to lose the tactile, contemplative quality that makes the practice settle the mind. There are also 64-card I-Ching decks — useful for travel or for people who prefer to draw rather than toss, though they collapse the changing-line system into a simpler one-card draw.
Connections
The I-Ching sits at the heart of Chinese divination and is one of the foundational texts of Taoist philosophy. For the full encyclopedic entry on the Book of Changes, its history, and the meaning of all 64 hexagrams, see the I-Ching reference. The practice pairs well with journaling and contemplative sitting — many practitioners cast a reading once a week and let the hexagram inform their reflection.
