I know the meaning of is krypton. But I find there are many people say: 这个游戏真好玩,我要氪金.
Now they have got the game and played it, so they needn't buy the game now, even sometime they say so when play a free game. So how to understand the meaning of it?

氪金 means pay, charge.


Even the players are playing a free game, they still could pay money for items in games (to become more powerful, etc).

Also see here.


I think it might originate in Japanese, where it is written as 課金, meaning that you pay real money to the game, to get some advantages (such as better equipment).

When the word come to Chinese, 課 (simplified: 课) has the same reading as 氪. So on the internet, it is sometimes written as 氪金. You might also see other forms.

  • For reference: Japanese 課金 (ka'kin)
