Nexon’s idle mobile game 'Maple Raising', which sparked controversy over a probability error, will accept applications for full refunds from noon on Feb. 5.

Nexon said in a notice on Feb. 4 it will take refund applications from Feb. 5 to Feb. 15. The refund covers the full amount paid in market stores from the game’s launch on Nov. 6 last year through 7 p.m. on Jan. 28, when the full-refund notice was announced. Refunds will be made within 1 month after the application period ends.

The full-refund measure stems from a probability error issue in 'Maple Raising'. The maximum value for 'Ability' stats, which are randomly reset using paid currency, did not appear for a month after launch due to a code error, and user backlash grew after it emerged that the issue had been patched without disclosure. Nexon decided on full refunds on Jan. 28, a first for the game industry. Sales for the refund-eligible period are estimated at 150 to 200 billion won.

Nexon also expanded compensation for an attack speed display error that occurred separately from the probability error. The issue was that the attack speed shown in the game was not reflected in actual performance, and Nexon doubled compensation in probability-based items used to adjust attack speed. 'Miracle Cube' and 'Additional Cube' were raised to 6 percent from 3 percent of total usage, and 'Medal of Honor' was increased to 12 percent from 6 percent.

Nexon removed the head of its Maple division from the post in early February and said co-CEO Kang Dae-hyun (강대현) will also serve as division head. The Fair Trade Commission has recently sent investigators to Nexon and begun an on-site investigation over the 'Maple Raising' controversy, the game industry said.

'Maple Raising' is an idle mobile game that Nexon co-developed with AbleGames and released in November last year. It ranked No. 1 in revenue on the two major app markets soon after launch, but has seen a series of probability-related controversies emerge this year.
