Board to Death gives us their in-depth, thought out reaction to Knee Jerk in this video review.
Man, I twisted my knee the other day emptying out one of the containers we got into the warehouse. Still hurts today.
From the website:
Think fast – the first player to give their knee-jerk reaction wins the point! Players rapidly create endings to funny situations in this 4-8 player party game. Each situation lasts 10 seconds, and players get to play simultaneously (i.e. no downtime!).
One player plays as the host, rapidly choosing and announcing situations. The first player to create a valid ending to the situation wins the point. If more than one player answers, the host picks his favorite. The first player to gain three points is the winner!
