Behind each bottle label there is a code: Why no one knows the result in advance

Nguyễn Tùng |

A small string of characters behind the bottle label is the starting point of the system designed so that no one can interfere with the results. So what determines the winner?

Opportunities that seem random

In the late afternoon, a convenience store near a university in Ho Chi Minh City is more crowded than usual. Pham Ha My (21 years old) stopped by as usual after school, chose a bottle of Zero Degree Green Tea and sat down for a few minutes before leaving. In the days leading up to the exam, she often needs a short break like that to cool down her life before returning to her homework.

While waiting for her friend, she paid attention to the familiar promotion program on the bottle label. "Seeing the promotion, I tore the label, took the code and tried to enter it, I didn't think much," she recounted. A few seconds later, the phone called and it said she had won 50,000 VND. "Being stressed because of studying and winning prizes, I felt happy and my head felt lighter," My smiled.

Since then, "drinking and then entering the code" has become a habit. "Each time I tear the label is a moment of suspense. The more I participate, the higher the chance of winning immediately and even a big prize in the month," My shared. A small action, but enough to create a highlight in the stressful exam days.

My's story is not unique. In the midday sun, many streets in Ho Chi Minh City are packed with vehicles as the number of delivery orders increases sharply. Mr. The Hien (30 years old), a technology driver, is busy completing orders when he stops at a roadside shop to buy a bottle of Dr Thanh Herbal Tea to cool down.

Just entering code for show, at that time my mind was still thinking about the few applications that had not been delivered," he recounted. But just a minute later, the phone called to report that he had won a 2 20,000 VND recharge card. "Not big, but used immediately to call customers, very convenient, saving a part of the cost," he said. For Mr. Hien, small rewards do not change his job, but enough to make a day less stressful.

Behind the codes: The "no human footprint" process

Prize-winning stories like My's or Hien's are often called lucky. But behind each code is a operating system with strict principles, without human "footprints".

Each lucky draw code consists of 9 characters, combining letters, numbers and special characters, creating hundreds of millions of different possibilities. From a mathematical perspective, guessing correctly is almost impossible. More importantly, each code is an independent opportunity: the more valid the code, the higher the probability of winning.

According to Mr. Hung, Factory Manager, on the production line, each bottle label is printed with a code in an instant, and right at that time, the winning - unwinning status has been determined. "There is no list to keep, no one knows which code wins or where the product will be distributed," he said.

We do not create a code and then determine the result. Each code when released has a fixed state and cannot be changed," Mr. Hung emphasized. When users enter the code, the system does not "determine" the result, but only returns to the original state.

From a technology perspective, the system is designed to ensure fairness for all participants. Each code is unique and secure. The winning results are random and always present. “There are thousands of winning people every day and this number is happening continuously,” Mr. Nguyen, Research and Development Manager of Packaging, added.

From small winning code entries, to the moment of 100 million

With more than 500,000 prizes allocated throughout the program, winning prizes are no longer rare. It happens every day, with ordinary people like Ha My or Mr. Hien. Small prizes may not change life, but they are enough to create joy and motivation in busy days.

At a larger level, all valid codes participate in the monthly draw to find the owner of the special prize worth 100 million VND. The draw sessions are publicly livestreamed on the official fanpage of brands, ensuring transparency for the entire process.

The moment the wheel stops, in just a few seconds, a code is identified and a winner is named in front of thousands of followers. No one knows for sure, no one has a better advantage.

From small prizes to special prizes, the entire system still operates according to a principle: no one can interfere with the results. The interesting thing is that the results are not about "guessing correctly", but about a very simple action: tearing the label and entering the code.

Every day, thousands of people win prizes not because they are luckier, but because they did not miss their opportunity. Just a few seconds of entering the code could be the boundary between slipping through the opportunity and actually touching it.

Because sometimes, opportunities are not far away, they are right behind the label on your hand.
