Korea Game Advertising Compliance: A Practical Guide to GSOK

Launching a game in Korea requires more than translating advertising copy. Marketing assets should be reviewed against Korean law, platform policies, age-rating requirements, and industry standards.

An important part of this framework is the Game Self-Governance Organization of Korea, commonly known as GSOK.

GSOK does not suspend advertising accounts, impose administrative fines, or order platforms to remove campaigns. However, it monitors game advertisements and may issue review findings, request corrections, or publish results through its self-regulatory process.

For global publishers, reviewing Korean advertising before launch can reduce last-minute revisions, user complaints, platform rejection, and reputational risk.

1. What Is GSOK?

GSOK is a private self-regulatory organization that promotes responsible practices in the Korean game industry and protects game users.

Its activities include:

• Developing self-regulatory standards
• Monitoring industry practices
• Reviewing game advertisements
• Operating expert committees
• Publishing reports and decisions
• Conducting policy and user-protection research

GSOK operates separately from government authorities such as the Game Rating and Administration Committee (GRAC) and the Korea Fair Trade Commission (KFTC).

It is also separate from advertising platforms. Google, YouTube, Meta, TikTok, and other platforms apply their own advertising policies, while Korean authorities may enforce applicable laws. The same advertisement may therefore be reviewed through several different processes.

2. Why GSOK’s Advertising Standards Matter

Game advertisements communicate gameplay, rewards, characters, and paid content within a short time. If an advertisement differs significantly from the actual game or omits important conditions, users may be misled.

GSOK’s standards generally focus on:

• Accurate descriptions of gameplay and rewards
• Clear information about paid content and conditions
• Appropriate violence and sexual content
• Protection of children and general audiences
• Responsible representation of probability-based items

Following these standards can help reduce deceptive advertising and improve trust in the Korean game market.

3. How GSOK’s Review Process Works

GSOK publishes reports based on its advertising monitoring and committee activities. The monitoring scope may vary, so publishers should not assume that only major campaigns or specific platforms will be reviewed.

A general review process may include:

1. Advertisement identification: An advertisement is identified through monitoring, a complaint, or another review channel.
2. Standards review: The creative is assessed based on its claims, visuals, gameplay accuracy, target audience, monetization, and reward information.
3. Committee review or notification: GSOK may review the issue through its committee process and notify the relevant business.
4. Business response: The advertiser may explain the creative, provide evidence, revise it, or discontinue the asset.
5. Follow-up: GSOK may conduct additional monitoring or publish the result under its procedures.

This is a self-regulatory process, not a government-issued administrative sanction or an advertising-account ban.

4. Major Game Advertising Risks

False or Exaggerated Gameplay

Advertisements should not create a materially misleading impression of the actual game.

High-risk examples include:

• Showing gameplay that does not exist
• Presenting a minor mini-game as the main experience
• Displaying unavailable characters, items, or rewards
• Omitting important conditions for receiving a benefit

Stylized presentation may be acceptable, but the overall impression should remain consistent with the product.

Misleading Claims

Terms such as “free,” “guaranteed,” “unlimited,” and “ad-free” should be used only when they can be substantiated.

For example, claiming that a game is “100% free” may be misleading if it contains optional purchases. An “ad-free” claim may also be inaccurate if only certain video advertisements are removed.

Violence and Suggestive Content

Advertisements distributed publicly may reach audiences beyond the game’s intended users. Creative teams should review graphic violence, sexualized imagery, degrading portrayals, content involving minors, and other material unsuitable for unrestricted audiences.

A game’s approved age rating does not automatically make every advertising expression appropriate for public distribution.

Ratings and Required Notices

Publishers should verify whether the correct game rating and any legally required notices appear in the advertisement.

Requirements may arise from Korean law, rating rules, platform specifications, or the advertising format—not solely from GSOK standards.

Probability-Based Items

Advertisements for games containing probability-based items must include applicable statutory notices.

Publishers should also ensure that claims involving obtainable items, acquisition rates, guaranteed rewards, pity systems, event bonuses, and increased-probability campaigns accurately match the game.

GSOK review does not replace Korea’s statutory probability-disclosure requirements.

5. Pre-Launch Checklist

Before launching Korean advertising, confirm that:

• Advertised gameplay and rewards exist in the promoted version
• Important conditions and promotional periods are clear
• Absolute claims can be substantiated
• Korean translations preserve the original limitations
• Violence and sexual content are appropriate for the audience
• The correct game rating and required notices are displayed
• Probability information matches the current game configuration
• Advertisements, landing pages, store listings, and in-game content are consistent
• Platform targeting and age settings are appropriate

Build a More Defensible Advertising Process

No review can guarantee that an advertisement will remain live or that a platform will approve every asset.

However, a consistent review process can reduce preventable risk by ensuring that the advertisement, landing page, store listing, and actual game communicate the same user experience.

Before launching a Korean campaign, review the creative against current GSOK standards, Korean legal requirements, and the policies of each advertising platform.
