Red Envelope Split Simulator

Simulate WeChat's random Red Envelope (Hongbao) splitting algorithm.

The Math Behind the Lucky Money

Sending digital "Hongbao" (Red Envelopes) is an incredibly popular social activity in China, especially during the Lunar New Year. WeChat's random distribution feature is famous for keeping groups engaged, as everyone hopes to be the "Luckiest King" (手气最佳).

Our Hongbao Simulator mimics the underlying mathematical algorithm used to generate these random splits, ensuring that every person receives at least ¥0.01 while keeping the distribution wildly random and fair.

It uses a 'double-mean' algorithm. The maximum amount any single person can draw is capped at exactly twice the remaining average amount. This guarantees that money is distributed dynamically without running out before the last person.

The person who randomly draws the highest amount of money in the group is crowned the 'Luckiest King' (手气最佳), a fun social flex in Chinese chat groups.
