Do toys or terrorists kill more people? Murder or suicide? In a deadly game of solitaire, you are asked to rank mortality risks from small to large.

This game uses real statistics about real risks. Warning: play leads to real knowledge about risk from plane crashes, heart disease, and snake bite. Your friends may not thank you.

This game is based on the psychology of risk, risk communication and gamification. It was designed by a law professor and a public policy game designer from Harvard. All research for the game is free and publicly available, including tips for other public policy game designers.
