Double Dose is a wild, drink-giving card game. It's a sequel to Dose that's playable alone or in conjunction with the original game. Compared to basic Dose, Double Dose includes cards that make players reveal truths, perform dares, and share their deepest, darkest history. It also integrates an online function that allows players to reload random rule, dare, truth, and never-have-I-ever suggestions via the website: dosecards.com.
Players race to play or trade all of their cards. Each card can change the color, advance the game, or make your friends drink. Cards are played on their color, but some cards allow players to trade their entire decks or otherwise change the game dynamics wildly. The winner is the first player to play all the cards.
Similar to UNO, once a player only has two cards, they must shout, "Dose!" before another player realizes it or else they must drink and draw two cards.
