At the July 10, 2026 domestic agent roundtable jointly held by Korea’s Ministry of Culture, Sports and Tourism (MCST) and the Game Rating and Administration Committee (GRAC), officials focused on practical violations of Korea’s probability disclosure requirements.
Many compliance failures are not caused by intentional manipulation. They often arise from incomplete disclosures, inconsistent data, or small implementation errors that developers and live-operations teams overlook.
The following checklist reflects the compliance issues discussed at the roundtable and recurring violations identified in Korea’s official probability disclosure guidance.
One of the most common mistakes is assuming that displaying probability information inside the game alone is sufficient.
Korea’s probability disclosure rules generally require applicable information to be displayed both within the game and on the game’s official website. Advertising and promotional materials are also subject to separate disclosure requirements.
Probability information is available through the in-game UI, but the same information is missing from the game’s official website—or the website displays outdated values after a game update.
Maintain probability disclosures in both the game and the official website, and verify that the following information remains consistent:
Whenever probability data changes, all applicable disclosure channels should be updated at the same time.
Displaying only the probability of obtaining a reward grade—such as SS, S, or A—may be insufficient if users cannot determine the acquisition probability of each individual item within that grade.
Insufficient disclosure:
Users can see the overall probability of receiving an SS-grade reward, but they cannot determine the probability of obtaining each item included in that grade.
List every obtainable item and disclose its individual acquisition probability.
For example:
The item-level probabilities should accurately correspond with the disclosed grade-level total.
Another recurring issue involves grouping different quantities of the same reward into a single probability range.
If users can receive different quantities, each quantity is a separate obtainable outcome and should generally have its own probability.
Insufficient disclosure:
This format does not allow users to determine the probability of receiving each specific quantity.
Disclose every obtainable quantity separately.
For example:
Avoid combining multiple results into a range or using an aggregated probability that prevents users from identifying the probability of each actual outcome.
Probability values must be expressed as percentages and displayed with the level of precision required under Korea’s probability disclosure rules.
A uniform decimal-place rule should not be applied to every probability value. The required rounding position depends on where the first non-zero digit appears.
Actual probability: 0.93512345%
Insufficient disclosure: ❌ 0.93%
Appropriate disclosure: ✅ 0.9351%
In this example, the first non-zero digit appears in the first decimal place. The value may be rounded at the fifth decimal place or lower, resulting in a displayed value of 0.9351%.
When formatting probability values:
Developers should not arbitrarily shorten decimal values or apply inconsistent calculation rules across different disclosure channels.
Probability disclosures must accurately reflect the game system and remain consistent across applicable channels.
A missing item, an outdated webpage, an improperly rounded value, or an undisclosed probability change can result in a compliance review even when the publisher did not intend to mislead users.
Disclosure violations may lead to correction requests, corrective orders, service-distribution risks, and potential civil liability when users suffer losses.
Before launching a game or deploying a probability-related update in Korea, confirm that:
Probability disclosure compliance should be integrated into the game’s development and live-operations workflow—not treated as a one-time legal review.
