The best way to stay updated with the latest codes in Anime Dimensions Simulator is by using this site. Because most often when you don’t, it’s more probable to end up with expired codes. Websites would have to be frequently updating their sites to provide valid information. There are usually 1-2 codes mentioned in the game’s description, then there’s usually more active codes on the socials, we do all the scavenging for you. It’s often difficult to find codes online (besides the game’s homepage), there are twitter account(s) and a discord server where codes are promoted for the fastest updates when codes are released.
We wouldn’t recommend searching online for codes besides discord and twitter.

The official twitter made by the developers of Anime Dimensions Simulator are @Coolbulls (@coolbullsAS) / Twitter

People may have problems when trying to join the official discord because of lots of requests to be joining the server or just a lot of members. Discord server: Discord
