Dumb and Dumber Drinking Game Rules

About the Dumb and Dumber Drinking Game

Play the Dumb and Dumber drinking game with real-time activity triggers synced to the movie. The full pack includes 104 hand-crafted triggers spread across Casual, Normal, and Hardcore difficulty levels — so you pick the pace before you press play. Every trigger is tied to a specific scene, line, or beat in the film, and MovieknurD fires them in real time so nobody has to track rules or count seconds.

Lloyd and Harry are two men whose stupidity is really indescribable. When Mary, a beautiful woman, loses an important suitcase with money before she leaves for Aspen, the two friends (who have found the suitcase) decide to return it to her. After some "adventures" they finally get to Aspen where, using the lost money they live it up and fight for Mary's heart.

The game runs the full length of the movie — about 1h 47m. Open it on your phone, tablet, or laptop, choose a difficulty, and press start when the film begins. Cinema Mode also works for theater showings, vibrating quietly when a trigger fires so you can play in public without disrupting the room.
