How to Read the I Ching Online

A short guide to three-coin casting on this site.

1. Optional question

   Write a clear question if you wish (max 500 characters). The question never enters the URL and does not change the coin results.

2. Toss three coins, six times

   Each click tosses three coins: Heads = 3, Tails = 2. Sums become 6 (old yin), 7 (young yang), 8 (young yin), or 9 (old yang). Line 1 is at the bottom.

3. Read the primary hexagram

   The six lines form the primary hexagram in the King Wen sequence. Read our modern commentary first.

4. Read every changing line

   Lines valued 6 or 9 are changing. This site shows all of them (all-moving-lines-v1), not a single “main” line only.

5. Read the relating hexagram if any

   When lines change, a relating hexagram appears. It sketches an associated situation — not a guaranteed future.
