Some lesser-known knowledge about the gambling industry, see if there's anything you didn't know.

Recently, I chatted with a few friends involved in gambling and discovered some interesting industry secrets, which I'm sharing here for those interested.

China is surprisingly the world's largest exporter of slot machines. Slot machines made in China are sold worldwide, and many of those found in casinos are Made in China.

The fruit slot machine was actually invented by Taiwanese, not by Europeans or Americans. Many venues in Southeast Asia still use them, originating from Taiwan.

Some industrial parks boost performance by pushing employees to their limits. When people are driven to the edge, performance indeed improves, relying not on intelligence but environmental stimuli.

The popular dewdrop chart in casinos was actually invented in Macau. Those who play Baccarat understand it, and many believe it can reveal trends.

People involved in sports arbitrage even study the weather, as rain, wind speed, and humidity can all affect the outcome of games. Some experts can predict unexpected results just based on the weather.

Southeast Asians are also deceived into going abroad to have their kidneys removed, not just Chinese. This industry is incredibly dark, and both those who gamble and those who run the gambling can end up in trouble.

The biggest gambling giant in Africa is actually a legal company from China, though it does not operate domestically. They play on a larger scale than anyone else.

The gambling market in Indonesia is particularly xenophobic. Newcomers basically have no chance to share in the profits, as local tycoons won't allow new players to enter and compete.

A major streaming giant, BXGX, is almost turning into a gambling company. The streaming rooms are full of probability games, similar to gambling, and their revenue is probably higher than that of regular gambling companies.
