A simple adaptation of the skill game with wooden blocks. This Jenga drinking game has a twist though: if you cause the tower to topple, you must finish your drink. The same regular Jenga rules apply with regards to how you can pick the blocks and whatnot.
Using the sharpie write down rules on various blocks so when the person removes that block they or everyone (based on the rule) have to follow/perform what the block said. You can make this a team effort with people writing various rules. Here are some ideas for drunk Jenga:
You can get very creative with these rules, just hope that your not the one who picks that crazy block! Remember, the person who knocks down the tower has to finish their drink and set up the tower again.
