Subsequently, it launched in Taiwan, Hong Kong, and Macau in May, followed by Korea in August. *Ragnarok Idle Adventure Plus* has achieved notable success since its global introduction, securing the top position in free downloads on Google Play in both Brazil and Singapore, ranking second in Thailand and the Philippines, and fifth in Malaysia.
