Frequently asked questions
Is Mondodeck free?
Yes. Mondos, the in-game currency, are earned by playing: they cannot be bought or sold.
How old do I need to be?
You must be 15 or older to create an account.
What do you do with my data?
Only what the game needs: your email address (or your Google or Discord account), your username and your collection. No ads, no trackers. You can delete your account at any time from the settings.
Where do the cards come from?
Every card comes from a Wikipedia article. Excerpts are under the CC BY-SA licence, images come from Wikimedia Commons under free licences, and every card shows its credit with a link to the article. Mondodeck is not affiliated with the Wikimedia Foundation.
What about battles?
Player battles are coming in a future update. Meanwhile, open your packs and grow your collection: your cards will be ready.
