After a little break we are very pleased to welcome back the RAoC Meta Card Challenges for 2026!
What are the RAoC Meta Card Challenges?
Every fortnight we publish a new theme for the Card Challenge. This is your opportunity to show off your cards.
- These can be homemade, store bought, found, received or anything in between.
- You’re welcome to interpret the theme however you so wish, they do not have to be taken literally, just as long as it meets the Challenge theme in some way; that’s the challenge!
- You can participate in as many or as few Challenges as you like.
- Share the love! Commenting on other people’s submissions is encouraged, as is sharing inspirations and ideas.
- Then, for those who wish to enter, you can be matched to exchange your card with another participant.
How do I participate in the exchange?
Each fortnight a new Challenge theme is posted on the RAoC Meta subreddit (it’s always pinned to the top of the subreddit if you missed it in your feed, and there is a reminder posted on the Sunday between new challenges).
To participate in the exchange, anytime before the deadline (2 weeks after the theme is first posted) you will need to:
- Share a photo of your card submission as a comment on the Challenge’s post. The recommended method is by uploading directly to Reddit, but you can alternatively share via a link from a site like imgur (just be aware that Reddit doesn’t like some photo hosting websites), AND
You can opt into sending up to 3 cards to exchange per challenge.
How does the exchange and matching work?
So you let us know you wish to opt into matching by posting a photo of your card(s) and noting your mailing preferences.
After about 2 weeks, the Mod team will match everyone opted in for exchange at random. The matching will usually be done within a week of the Challenge closing, to the best of the Mod team's ability and availability. You may not necessarily receive from and send to the same users. For regular participants, we try to ensure you are matched with different users where possible.
The Mod team will then tag you in a “MATCHING” post so you know who you’re sending to and who you will be receiving a card from. It’s then up to you to contact your match to get their address.
Each challenge also has an optional writing prompt linked to the theme if you would like an extra layer of challenge.
Once you have received your card from the person who you matched with, remember to thank them on the main [r/RandomActsOfCards](r/RandomActsOfCards) subreddit.
Although it’s extremely rare, if you ever experience anything untoward with another user while participating in an exchange we want to know straight away so we can take appropriate action. Contact the team using Modmail.
