Look closely.
Study hexagrams through a named edition and translation of the Book of Changes. A consultation record includes the method, line sequence, text and subsequent reading.

Use the three-coin method: heads count as 3 and tails as 2. Cast six times, placing the first total at the bottom. Totals 6 and 9 change polarity; 7 and 8 remain stable. Record the original and relating hexagrams before consulting a named textual tradition.

Cast six lines with three coins, from bottom to top, and identify the changing figure.

Three coins. Six lines.
Portrait / heads = 3. Maltese cross / tails = 2. Totals: 6 changing yin, 7 stable yang, 8 stable yin, 9 changing yang. The first cast is line 1 at the bottom. This is the three-coin method, with probabilities 1:3:3:1 for 6, 7, 8 and 9. Each action requests one camera sample; Cast all six lines shares that sample across its 18 tosses, with fresh browser randomness for every toss.
How this draw works
The server takes up to 128 KiB of JPEG image data from one fixed stream, with a two-second timeout, and mixes it with fresh system randomness using SHA-512. The browser uses the same source module as the standalone key tool and mixes this response with its own random seed and uses fresh browser random words for each result. Rejection sampling avoids modulo bias. If the sampler is unavailable, results use browser randomness and the status says so.
Samples are experimental: no physical entropy rate has been established. Camera delays and repeated frames are possible. No predictive meaning is assigned to results. History stays in this page and clears when you leave or reset.
