Whales, Sharks and Gift Vouchers: How a 2006 Arcade Scandal Still Blocks Crypto Games in Korea

On the screen, a cartoon ocean. Fish drift by, coins tumble, and then a whale or a shark glides across the reef. To a regular player in 2006, that animal meant one thing: a jackpot was coming. The game was Bada Iyagi, "Sea Story", and in the summer of 2006 it was everywhere in South Korea.

It is also the reason Korean players cannot legally play blockchain play-to-earn games in 2026. When a Seoul court threw out a P2E developer's lawsuit on 31 January 2023, it explained the ban on in-game prizes by pointing straight back to the Sea Story scandal. This is the story of how a fish-themed arcade machine shaped the future of crypto gaming in one of the world's biggest game markets.

A government plan that went wrong

The road to Sea Story began with good intentions. In 2002, the Kim Dae-jung government approved gift vouchers (상품권) as legal prizes for arcade-style games, part of a push to grow the culture industry. A player could win vouchers, not cash, so the machines were not casinos on paper.

In practice, the vouchers became money. Next to many game rooms sat small "exchange centres" that bought vouchers back for cash at roughly a 10 percent discount. A player fed in a 10,000-won note, won vouchers and walked next door to swap them for won. Korea's legal casinos at the time numbered 17, and only one of them allowed Korean citizens to gamble. Sea Story rooms filled the gap.

How big it got

By August 2006 the numbers were staggering, even allowing for the fact that some were estimates made in the heat of a political storm:

• About 20,000 slot-style game rooms were operating nationwide, according to a Korea JoongAng Daily report.
• A legislator said vouchers issued since July 2005 added up to 27.7 trillion won.
• A National Intelligence Service report cited at the time estimated annual operator profits at 50 trillion won, around a third of that year's government budget.
• About 19 companies held approval to issue vouchers. Large issuers processed 2 to 3 million vouchers a day.

The approved versions of the machines had strict payout limits. Many rooms ran modified boards that paid far more, which turned a regulated amusement into high-stakes gambling.

Everyone took a cut

What made the system so hard to kill was that it paid almost everyone along the chain. Reporting in 2006 broke down the flow of a single voucher. The distribution centre that supplied game rooms took a commission of around 70 to 80 won per voucher. Exchange centres paid issuers about 50 to 55 won to replace each used voucher, and distributors kept 20 to 25 won. Even after costs, an issuer could net 20 to 30 won per voucher, and the volumes ran into millions a day.

Even a state-linked body was in the loop. Issuers paid the Korea Game Development and Promotion Institute, which designated them, a fee per voucher: 5 won each for the first 50 million 5,000-won vouchers and 2 won after that. Over one year to July 2006 the institute collected 14.6 billion won. When the scandal broke, that fee became one of the most uncomfortable facts for the government.

The summer it all came down

Sea Story rooms had spread across the country for about two years before the media storm broke in August 2006. Then it moved fast. Prosecutors raided the offices of the voucher issuers in what they called their biggest raid ever and banned dozens of people linked to them from leaving the country. Prime Minister Han Myeong-sook ordered the closure of thousands of game parlours suspected of illegal gambling, and the scandal was called a "failure in policymaking". Opposition lawmakers alleged political lobbying, and the culture ministry and the old media rating board blamed each other.

The law that came out of the wreckage

The clean-up gave Korea the rulebook it still uses. The Game Industry Promotion Act had been promulgated on 28 April 2006 and took effect on 29 October 2006, just as the scandal peaked. Its first enforcement decree required review of the software inside prize-paying machines to make sure it could not be tampered with, banned prizes at internet game rooms and limited gambling-type venues to opening between 9 a.m. and midnight.

The country also got a dedicated game rating board in late 2006, taking games away from the media rating body that had approved the machines. Vouchers were scrapped as prizes from April 2007. And a 2007 amendment, Law No. 8247, added the clause that matters most for crypto today: Article 32(1)7, which bans any business of exchanging, brokering or buying back the points, prizes and game money that players earn in a game.

From fish to tokens

Fifteen years later, the same law met a new kind of game. In 2021, developers began releasing play-to-earn titles whose tokens could be swapped on crypto exchanges. To Korea's regulator, the structure looked familiar: play, earn a tradable prize, convert it to cash at a third party.

The Game Rating and Administration Committee (GRAC) cancelled the ratings of P2E games, and the courts agreed. In the January 2023 ruling against Natris's Muhandolpa Samgukji Reverse, the Seoul Administrative Court said that offering prizes is itself a gambling-promoting act and cited the lawmakers' aim after the Bada Iyagi affair. It treated the game's token as a prize under Article 28(3) and found that a game that hands out crypto to attract players could be a "new form" of gambling game (the court cases in full).

That is why Korean P2E debates sound so different from those abroad. Elsewhere, the questions are about securities law or consumer protection. In Korea, every argument passes through the memory of 2006.

By the numbers

• 2002: gift vouchers approved as arcade prizes
• About 20,000: slot-style game rooms reported in August 2006
• 27.7 trillion won: vouchers issued since July 2005, as claimed by a legislator
• 17: legal casinos in Korea in 2006, only one open to Koreans
• 29 October 2006: the Game Industry Promotion Act takes effect
• April 2007: vouchers end as prizes

What to watch

The 2006 law is finally being rewritten. A full revision proposed by lawmaker Jo Seung-rae in September 2025 would rename and restructure the act and limit the prize ban to arcade-style "location-based" games. Supporters say it moves games from regulation to promotion; critics, including the culture ministry, warn it could leave online P2E unregulated (our explainer on the debate).

WGC's take: Sea Story was a real disaster, and the rules it produced did their job against gambling arcades. The open question is whether a law written for fish-themed slot machines is the right tool for games where players genuinely own their items. That is a question for lawmakers, and Korea is finally asking it.
