How to Cast Coins for I Ching Divination: A Step-by-Step Guide

The coin method is the easiest and most popular way to consult the I Ching. You don't need anything fancy — just three ordinary coins, a quiet moment, and a clear question. This guide walks you through the entire process, from setting up your space to interpreting the resulting hexagram.

What You Need

Before you start, gather these items:

• Three coins — Any coins work. Pennies, quarters, euros, yen. Some people keep a special set of three Chinese coins (with the square hole in the center) for their practice, but it's completely optional. What matters is your intention, not the hardware.
• A flat surface — A table, desk, or floor. Somewhere you can toss the coins without them rolling away.
• Paper and pen — You'll record each line as you go. Even if you're using an app or our online guidance tool, writing things down helps you stay present.
• Your question — Written down in one clear sentence. If you're not sure how to phrase it, read our guide on asking questions first.

Step 1: Prepare Your Mind and Space

The I Ching isn't a party trick. The quality of your reading depends heavily on the quality of your attention during the casting process. Here's what I recommend:

• Find a quiet place where you won't be interrupted for about 10 minutes.
• Take three slow breaths. Let your mind settle.
• Hold your question clearly in your thoughts. You can say it out loud: "I am asking about..." or just hold the intention silently.
• Some people like to light a candle or incense. Others don't. Do whatever helps you feel focused and grounded.
• Hold the three coins in your hands for a moment. Feel their weight. This is your moment of connection with the oracle.

The key is presence. You're not just flipping coins randomly — you're entering a dialogue with a 3,000-year-old tradition. Treat it with the respect it deserves, and it will respond in kind.

Step 2: Understand What Each Toss Means

Each coin toss produces a number, and that number determines one line of your hexagram. Here's the system:

Coin Combination	Numerical Value	Line Type	Symbol
Three heads (3 + 3 + 3)	9	Old Yang — changing to Yin	—o—
Two heads, one tail (3 + 3 + 2)	8	Young Yin — stable Yin	— —
One head, two tails (3 + 2 + 2)	7	Young Yang — stable Yang	———
Three tails (2 + 2 + 2)	6	Old Yin — changing to Yin	—x—

Heads counts as 3. Tails counts as 2. Add the three coins together and you get a number from 6 to 9.

• 6 (Old Yin): A changing Yin line. It's Yin now but about to become Yang. Shown as a broken line with an "x" in the middle: —x—
• 7 (Young Yang): A stable Yang line. Solid and unchanging: ———
• 8 (Young Yin): A stable Yin line. Broken and unchanging: — —
• 9 (Old Yang): A changing Yang line. It's Yang now but about to become Yin. Shown as a solid line with a circle: —o—

The "changing" lines (6 and 9) are the most important part of any reading. They show where the energy is actively shifting — where the action is. We'll explore this deeply in our guide to interpreting moving lines later in this series.

Step 3: Cast Six Times

Now comes the actual casting. Here's the crucial detail that many beginners miss: you build your hexagram from the bottom up.

This is the opposite of how we normally read (top to bottom). In the I Ching, the first line you cast becomes the bottom line (Line 1), and the sixth toss becomes the top line (Line 6). Think of a plant growing from the ground up — that's how a hexagram grows.

The Casting Process

1. Toss 1 (Bottom Line — Line 1): Shake the three coins in your hands, focus on your question, and toss them onto your surface. Count heads and tails. Write down the result at the bottom of your paper.

2. Toss 2 (Line 2): Repeat the process. Write the result above Line 1.

3. Toss 3 (Line 3): Write it above Line 2. This completes the lower trigram — the bottom three lines that represent the inner or personal aspect of your situation.

4. Toss 4 (Line 4): Now we're building the upper half. Write it above Line 3.

5. Toss 5 (Line 5): Getting close. Write it above Line 4.

6. Toss 6 (Top Line — Line 6): The final toss. Write it at the very top. You now have a complete six-line hexagram.

Example: A Real Casting

Let's say your six tosses produced these numbers, from bottom (first toss) to top (sixth toss): 7, 8, 9, 8, 7, 6.

Your hexagram looks like this:

Line 6:  —x—  (6, Old Yin — changing)
Line 5:  ———  (7, Young Yang — stable)
Line 4:  — —  (8, Young Yin — stable)
Line 3:  —o—  (9, Old Yang — changing)
Line 2:  — —  (8, Young Yin — stable)
Line 1:  ———  (7, Young Yang — stable)

This is Hexagram 3: Difficulty at the Beginning (/library/3), with moving lines at positions 3 and 6. The changing lines are especially significant — they contain the most specific, time-sensitive advice for your situation.

Step 4: Identify Your Hexagram

Now you need to figure out which of the 64 hexagrams you've received. There are several ways to do this:

• Use our tool: Go to /divine and enter your six line values. It identifies the hexagram instantly and provides a full interpretation.

• Use a lookup table: Many I Ching books and websites have tables that map trigram combinations to hexagram numbers. The lower trigram (lines 1-3) and upper trigram (lines 4-6) each correspond to one of the eight basic trigrams (☰ Heaven, ☱ Lake, ☲ Fire, ☳ Thunder, ☴ Wind, ☵ Water, ☶ Mountain, ☷ Earth).

• Visit our hexagram library: Browse all 64 hexagrams and find yours by matching the line pattern.

In our example above, the lower trigram is ☳ Thunder (one Yang line between two Yin lines), and the upper trigram is ☵ Water (one Yang between Yin). This gives us Hexagram 3.

Step 5: Read Your Hexagram — Start with the Big Picture

Before you dive into the line texts, read the hexagram's judgment (卦辞). This is the overall message, the headline. It tells you the nature of the situation you're in.

For example, Hexagram 3's judgment says: "Difficulty at the Beginning works supreme success, furthering through perseverance. Nothing should be undertaken. It furthers one to appoint helpers."

Already we know something important: this situation is hard right now, but the difficulty is natural. The advice is to persevere and get help — not to force things or give up.

Also read the image (象辞). For Hexagram 3: "Clouds and thunder: the image of Difficulty at the Beginning. Thus the superior man brings order out of confusion." This adds another layer: the chaos you're experiencing is pregnant with potential. Your job is to find the pattern within the chaos.

Step 6: Interpret the Moving Lines

If you have any changing lines (6 or 9), these are your most important messages. Each moving line has its own text that speaks directly to the dynamic aspect of your situation.

In our example, we have a moving line at position 3 (Old Yang) and position 6 (Old Yin):

Line 3: "Whoever hunts deer without the forester only loses his way in the forest. The superior man understands the signs of the time and prefers to desist. To go on brings humiliation."

This is a warning: don't charge ahead without guidance. You need a "forester" — someone who knows the terrain. Going it alone will get you lost.

Line 6: "Horse and wagon part. Bloody tears flow."

This is the most intense line — it speaks of separation, loss, things falling apart. But remember, this is a changing line. The separation is happening so something new can emerge.

The Transformed Hexagram

When lines change (from Yin to Yang or Yang to Yin), you get a second hexagram — the transformed hexagram. This shows where the situation is heading after the change.

In our example, Lines 3 and 6 flip:

• Line 3: Old Yang (———) → Yin (— —)
• Line 6: Old Yin (— —) → Yang (———)

The transformed hexagram becomes Hexagram 8: Union (/library/8). The difficulty gives way to connection. The tears lead to realignment.

This is the beauty of the I Ching: it doesn't just describe a static situation. It shows you the movement, the direction, the arc.

Common Questions About Coin Casting

"Do I need special Chinese coins?" No. Any three coins of the same type work perfectly. The I Ching is about intention, not special hardware. People use special coins because it helps them take the process seriously, not because the coins themselves have magical properties.

"What if a coin rolls onto the floor?" Pick it up and read it where it landed. Some traditions say this is significant — the oracle is emphasizing that line. Others say just re-toss. I'm in the former camp: the oracle gave you that result for a reason.

"How many times can I ask the same question?" Once. The I Ching, through Hexagram 4: Youthful Folly (/library/4), warns us: "At the first oracle I inform him. If he asks two or three times, it is importunity. If he importunes, I give him no information."

Asking the same question repeatedly is like shaking a Magic 8-Ball until it says what you want to hear. The oracle takes your first question seriously. Your second and third? Not so much. If you didn't like the answer, sit with it. The discomfort might be the most valuable part.

"Can I use a digital tool instead of coins?" Absolutely. Our online guidance tool uses the same principles — it generates random line values, identifies your hexagram, and provides a full interpretation. The physical act of tossing coins can feel more ceremonial and grounding, but the digital method is equally valid.

Practice Exercise

Before you ask a real question, try a practice run:

1. Ask: "What should I understand about learning the I Ching?"
2. Cast six times with real coins.
3. Record your results.
4. Look up your hexagram in our hexagram library.
5. Read the judgment and image.
6. Note any moving lines and read their texts.
7. Reflect: what does this tell you about your learning journey?

This practice question is safe and genuine — you're actually asking something real, but it's low-stakes. It's the perfect way to get comfortable with the process before you bring your deeper questions.
