I Ching Oracle — Cast & All 64 Hexagrams
Cast a genuine random I Ching hexagram using the traditional three-coin method (not a shortcut single-random-pick), or browse all 64 hexagram meanings on their own as a standalone reference.
The traditional three-coin method produces one of 64 hexagrams along with any 'changing lines' that point toward a second, resulting hexagram — genuinely randomized here rather than always landing on the same illustrative example — and every one of the 64 meanings is also browsable on its own as a standalone reference.
Frequently Asked Questions
How does the traditional three-coin I Ching casting method work?
Each of the six lines is built by tossing three coins at once: heads counts as 3, tails as 2, summed per line from the bottom up. A sum of 6 or 9 is an 'old' line, 7 or 8 is a 'young' line — this tool runs that exact method with real client-side randomness.
What does a 'changing line' mean in a cast hexagram?
A changing line is one where all three coins agreed — a sum of 6 or 9. Traditional interpretation treats it as already turning into its opposite, so changing lines flip to form a second, resulting hexagram.
How many hexagrams does the I Ching have?
64 — every possible combination of six broken (yin) or unbroken (yang) lines, built from two of the 8 three-line trigrams stacked as upper and lower halves.
What's the difference between the primary and resulting hexagram after a cast?
The primary hexagram is your six cast lines read exactly as thrown. A resulting hexagram only appears if at least one line was 'changing' — those lines flip to form a second hexagram read alongside the first.
Is the coin toss in this online I Ching tool actually random?
Yes — each of the eighteen coin flips uses genuine client-side randomness generated fresh every time you click Cast the Coins, not a fixed or pre-selected outcome.
