Drinkocity

INTRODUCTORY SALE PRICE!!! Normally $2 USD, but currently on sale for $1 USD for the first 500 downloaders!
Drinkocity is a fun, fast-paced drinking game for any number of players, but ideally you would have 6-20. Players can drop in and out at any time without disrupting the flow of the game, and all you really need is a phone to play it on. There are 10 different card types with 100 unique cards per type in the paid version, thats 1000 different cards! Plus, there is also an 11th card type called Mini-Games where players interact with each other doing battle in dozens of different ways. For these you might need a few coins, a table, and/or a cup, but that shouldnt be too hard to find at a party.

Some cards are trivia based, some are not, and some just make you drink for various reasons. Full instructions for each card type are available in-game, so I wont go into them here. Basically each turn consists of a player reading a question (or directive) aloud to the group and awaiting an answer, the correct guesser then gives away drinks to the other players. After the card is over, you pass the phone to the player to your left and they now read.

Many other card types are shown on the free version page.
