The Korea Game User Association (KGUA) has filed formal complaints with the Fair Trade Commission for violations of the E-commerce Act and requested user damage relief from the Game Rating and Administration Committee against five developers for misrepresenting or omitting loot box odds.

The list of companies in the hot seat includes 111% (Random Dice: GO), Com2uS (Com2uS Pro Baseball V26), CookApps (Cat Ninja), SESISOFT (Cheonsangbi M), and Gravity (Ragnarok Idle Adventure PLUS).

The Association has been granted legal authority by a massive cohort of players, including 863 users from Random Dice: GO and 493 from Com2uS Pro Baseball V26, all seeking restitution.

Random Dice: GO admitted to a 'probability bias' in pet and rune gacha pulls, where certain items appeared more frequently than intended. Further suspicions are also being raised regarding their altar, relic, and figure systems.

Com2uS Pro Baseball V26 operated a feature for resetting potential slots using paid currency without disclosing the probability information. When users inquired, the company refused to provide information, claiming internal odds were confidential. They later disclosed the odds but failed to offer any compensation.

Cat Ninja displayed different odds in-game compared to their website and failed to notify users of probability changes. Furthermore, serious errors occurred, such as items appearing that were not listed on the probability table, yet the developer did not take immediate corrective action.

In Cheonsangbi M, cases occurred where enhancement items marked with a 100% success rate failed. The developer only restored the items for the specific affected cases and did not provide a satisfactory explanation or compensation regarding the broader probability error allegations.

Ragnarok Idle Adventure PLUS changed their roulette event odds mid-season without prior notice. After users protested that they could not obtain normal rewards, the studio admitted there was an issue with the actual probability and issued refunds for that period.

KGUA Chairman and lawyer Lee Chul-woo stated, "Probability data for loot boxes is a decisive factor in consumer choice. The fact that these controversies persist despite discussions on introducing punitive damages and imposing fines is proof that the domestic game industry remains overly fixated on loot box-based monetization."
