Board Game Arena

Some released projects seem to be missing, like Tiki.

Also some projects don't have read-only access available which would make it quite hard to bounty hunt, like Tz'olkin for example.

Not all adaptations were made in studio. And read-only access is not obligatory, sometimes publisher doesnt want to have the code accessible or developer doesnt want to..

For bounty hunt you can always request the source data from admins, like it says so at the Bounty hunt page..
