The game itself is pretty simple, so once players understand what each card does, they won't need to read any text to play. We've tested a few times with people who don't speak any English at all and after a round or two they got right into it.
We're also crowdsourcing translations of the rulebook. If you want to help, have a look at our spreadsheet here: https://docs.google.com/spreadsheets/d/1F_mQtOSJuUVAdzItllQ0Njmoy0qklnTBC0egR0k5bXU/edit?usp=sharing
If your language is already represented, give it a proofread or help them finish. If there's no tab for the language just send us a message and we'll add it!
