Details and Conditions
Jackbox Games is known to make their games friendly for content creators and streamers and has a few mentions of it on their website and knowledge base, but no specific policy when it comes to monetization. There is a 2015 response by the developer in regards to this question for The Jackbox Party Pack 2 Steam discussions (source linked below). I would recommend contacting the developer just to be safe.
What it Means
Videos and streams SHOULD be allowed
You SHOULD be able to monetize on YouTube and Twitch with ads and subscriptions
You MIGHT NOT be able sell or charge for access to your content (this would include Twitch "subscriber only" streams or selling merchandise)
Any licensed IP or music not owned by the publisher are not covered by this policy
