Kinh Dịch AkiNet 2.20: record real-coin casts, Star refund

Kinh Dịch AkiNet 2.20.0, released on 26 September 2026, does two things: it lets you record a cast made with 3 real coins in the app, and it fixes the six-kin (lục thân) roles of the changed hexagram, which had been wrong since the feature launched. Paying users whose readings were affected get exactly the Stars they spent back: 2,608★ in total across 52 users.

How does recording a real-coin cast work?

You toss 3 coins in real life, then log each line in the app: for every toss, pick one of 4 pictured outcomes (0, 1, 2 or 3 yang sides), six times from line 1 to line 6. Tap a logged line again to correct it. On modern coins the side showing the denomination is yang; on old coins the side with characters is yang.

The cast time defaults to now, and you can change the date, time and time zone. The app shows the day and hour Can Chi right away, and warns when the time sits close to a solar-term boundary or 00:00. A recorded cast is read like any cast made in the app and shares the same cast quota.

The real-coin guide pictures the yang and yin sides, the preparation steps, calming the mind, and the folk custom "men shake 7 times, women shake 9". Five new articles come with it: recording a cast, yang and yin sides, calming the mind, casting abroad, and Nhật Thần / Nguyệt Lệnh.

Which time zone sets the day and hour Can Chi?

Day and hour Can Chi now follow the time zone where you cast, no longer fixed to Vietnam time. History shows each cast at its own local time. Casts made before this version keep their saved Can Chi.

What was the changed-hexagram error and who was affected?

When a line is moving, the primary hexagram turns into a changed hexagram. Classical Six-Line practice takes the palace element of the primary hexagram as "self" to name the six-kin roles of the changed lines. The app took the palace of the changed hexagram itself. Whenever the two hexagrams sit in palaces of different elements, the role labels of the changed hexagram are off. The error dates from June 2026, when the feature launched, and no test caught it.

A real example: primary hexagram Tiệm changing into Sư, line 6 must be Tử Tôn (Earth produces Metal) and line 3 must be Phụ Mẫu (Fire produces Earth). The old version labelled both lines differently, and the reading built its argument on those wrong labels.

2.20.0 fixes it in one place, the function that builds the hexagram result, so the casting table on every screen and the data sent to the AI are correct at once. The changed-hexagram table also stops showing its own Thế/Ứng, since Thế/Ứng belong to the primary hexagram.

Who gets Stars back, how many, and why?

Conditions: a completed paid reading (Học Đồ or Đại Dịch Sư) whose changed hexagram sits in a palace of a different element from the primary hexagram, created before the fix went live at 20:20 on 26 September 2026 (Vietnam time). Result: 72 readings, 52 users, 2,608★. Internal accounts of the operating team are not on the list.

The refund equals exactly the Stars you paid for the affected readings (9★ per Học Đồ reading, 79★ per Đại Dịch Sư reading). So each person receives a different amount, not a flat sum. Each gift carries a note naming which cast was affected, so you can reopen it in History, where the changed-hexagram table is now correct.

The Stars are added to your wallet when you claim the gift, like a regular Star gift. An account that already holds a gift with the same note is never gifted twice.

What else changed for the Great Master?

In follow-up questions, Đại Dịch Sư no longer leaks the English word "child" into its answer (it had appeared in 18 of 91 follow-up turns), and addresses you more consistently.
