Playing The Game

I Doubt It is a basic, turn-based, card game. The object is to get rid of your cards before your competitors. At the start of the game, a 52 deck of cards is shuffled, and dealt evenly to all players, exactly (remainders are placed in the discard pile). If a large amount of players are present, two decks are shuffled together. The game is organized by rounds, in which everyone takes a turn. When it is your turn, you will be presented with a checklist (use the up/down key, spacebar to check cards and press enter when done-if you downloaded the client) of the cards you were dealt, and will be told the rank of the card you need to match-similar to Uno. The "round card" (rank) is Ace all the way up to King, and increases (from Ace to Two, Two to Three, etc) after every round. You must play at least 1 card, and the cards you play are placed face down, and into the discard pile.

Unlike Uno, however, you may play any card you wish-- remember, the cards are played face down. You do NOT have to match the rounds card, in fact, you will sometimes have to play card(s) that do not match, because you do not have any that match. The "fun" of the game comes from the name: I Doubt It. If you think another player did not match the card they were supposed to (all cards played must match), then you may Doubt, or "Challenge" the play (press the I hotkey). See next section for information on Challenging.


During a challenge, the player is forced to reveal what cards he or she actually played. If the original player was right, matching the round card, then the challenger must take all cards from the discard pile. If the challenger was right, then the original player must take all cards from the discard pile. The first person to get rid of all of his or her cards is declared the winner.

Winning The Game

The first person to get rid of all of his or her cards wins the game. This player must last through the challenge period, though, challenges work the same way every time. A player may put down his or her last card, be challenged, and be forced to take all the cards in the discard pile.
