The idea for this jam comes from Neighborhood Brawl, by Micah Anderson.

Some board games are played out. They can get boring approached the same way over and over again.

Let's fix that.

Pick a board game, any board game. Design a set of house rules that turn the board game into something new. 

Bonus points if you use only the materials provided by the board game. No outside cards, dice, miniatures, etc. (This isn't a requirement. I might end up breaking this rule too.)

I recommend releasing the house rules for free since a lot of board games are covered by copyright. Do your research.

Extra Credit: 
Print out your rules. 
Locate your board game in a thrift store or some second hand shop. 
Plant your rules in the box. 
Leave for some unsuspecting future owner.
