Codes are words or phrases with no spaces which can reward players with Currency, Resource Energy, Card Packs, and/or Rune Fragments when redeemed (previously, they were often randomly generated alphanumeric strings of 30 characters). They are given out on the Idle Online Universe Facebook Page and in #codes in the Idle Online Universe Discord server. Wood and Stone currencies were replaced with NRG shortly after the 3rd Q & A with Ray was released on January 11, 2018.
Codes are released weekly on Sundays and reward various currencies (changed from two daily codes with fewer rewards as of v1.27.0). There is a chance to get a "jackpot" which will be announced in world chat.
How to redeem a code Edit
Extra spaces are automatically trimmed as of 0.51 Zeta. Note that codes are case sensitive.
