Ragnarok Online (Korean: 라그나로크 온라인, Rageunarokeu Onrain marketed as Ragnarök, and alternatively subtitled The Final Destiny of the Gods) is a massive multiplayer online role-playing game (MMORPG) created by Gravity based on the manhwa Ragnarok by Lee Myung-jin.

Non-player character-run challenges and contests are also available with prizes, awards, and/or in a specific hall of fame listing.

Players can sign up for quests and submit them for rewards as well as access storage and teleport services for a small fee.

Quests usually provide a unique reward such as learning a new skill or receiving a rare item.

These transcended job types have more skills and a larger number of 'stat points' to allocate to characters compared to second classes.

Gravity partnered with SkyZone Entertainment to release a series of standalone mobile phone games that supplement Ragnarok Online.

Players are given the ability to transfer earned zeny (the in-game currency) to their Ragnarok Online game account.
