Two things, in two places. Since March 2024, Korea's probabilistic-item rules under the Game Industry Act have required the odds for paid probabilistic items to be displayed both inside the game itself and in any advertising for it. Most compliance failures on the public record are not about hiding odds altogether; they are about displaying them in the wrong place, in the wrong form, or for the wrong unit — and the corrective orders are specific about each.

The duty, in its parts

  • In the game and in the advertising. Disclosure inside the game alone does not satisfy the rule. The odds travel with the marketing as well.
  • Individual odds for capsule-type items. For capsule-type items, the required disclosure is the individual probability of each item, not a category aggregate.
  • The required form. The rules prescribe how the figures are shown, down to the decimal places. Odds displayed in a nonconforming format have been written up as a violation in their own right.
  • Variable odds and ceiling rewards. Where probabilities change with conditions, and where a ceiling mechanic guarantees a reward after a set number of attempts, those figures are part of the disclosure too.

What corrective orders have actually cited

The enforcement record is the best guide to where the rule bites, and it is public. In late December 2025, Korea's culture ministry issued corrective orders to two foreign game publishers over probabilistic-item disclosure (notice nos. 2025-0389 and 2025-0390), serving both by public notice because neither company had a Korean address on file. A further order in January 2026 (notice no. 2026-0026) cited the individual odds of capsule-type items not being displayed, and the display format — the decimal-place requirement — not being met. A June 2026 advance notice (notice no. 2026-0220) concerned the variable odds of container contents not being displayed, and a corrective order the same month (notice no. 2026-0235) listed five separate items across recruitment-style draws and fragment mechanics: probability information, variable odds, and ceiling-reward odds not displayed, alongside display-method failures.

Read together, the citations form a pattern. The regulator is not only checking whether a probability table exists somewhere; it is checking each disclosure element separately — individual odds, variable odds, ceiling odds, format, and placement — and writing up each gap as its own item.

What to check first

  • Inventory every paid probabilistic mechanic. Capsule items, containers, recruitment-style draws, fragment systems, ceiling counters — the disclosure duty follows the mechanic, not the label the game gives it.
  • Check the advertising surface, not just the game client. The in-game table is the half of the duty most teams complete first; the advertising half is the one the rule also names.
  • Check the format against the rule, not against habit. A disclosure that exists but rounds figures differently than the prescribed form has been treated as a gap on the same footing as a missing table.

Why foreign publishers see this late

Every order named above was served by public notice, because the publisher had no Korean address to deliver it to. That mechanism — service by posting on a public board, deemed delivered whether or not it was read — is covered in our separate note on public-notice enforcement. The short version: a publisher with no domestic contact may learn of a disclosure finding only after it is on the public record. The disclosure duty and the domestic-agent question are, in practice, one subject.
