Online moon block toss | Shengjiao, Xiaojiao, and Yinjiao simulator
A respectful entertainment simulation of Taiwanese Jiaobei culture: Web Crypto selects the faces before the 3D blocks animate.
How do I use the moon block simulator?
- Ask a clear yes-or-no question: Think of one specific question, or type it into the optional field before tossing.
- Toss the two 3D blocks: Select the toss button. Web Crypto chooses both faces first, then the 3D scene replays that result.
- Read the result or try the streak challenge: One flat and one rounded face is Shengjiao, two flat faces are Xiaojiao, and two rounded faces are Yinjiao. Three Shengjiao results unlock a bonus fortune.

Randomness and privacy
Each block independently uses Web Crypto to choose a flat or rounded face. The theoretical probabilities are 50% Shengjiao, 25% Xiaojiao, and 25% Yinjiao; three consecutive Shengjiao results are 12.5%. The question stays in this browser. This is an entertainment simulation, not religious guidance.
Frequently asked questions
- What do the three moon block results mean?
- In this party simulation, one flat and one rounded face is Shengjiao, two flat faces are Xiaojiao, and two rounded faces are Yinjiao.
- What is the chance of three Shengjiao results in a row?
- Each toss has a theoretical 50% Shengjiao chance, so three independent Shengjiao results have a 12.5% chance.
- Does the 3D physics choose the result?
- No. Web Crypto chooses the two faces first; the 3D motion only presents the selected outcome.
