Historically, the game is mainly played in Syria, Lebanon, Palestine, Jordan, Honduras, and The Philippines.
Unlike Spades, in 400 a hand will be considered void if the total sum of all four bids is under eleven.
As noted above, the total bids must equal 11 in order for a hand to begin.
However, some local house rules stipulate that when a member of any team reaches 30 points, the total bids in the hand must equal 12 for the hand to begin, because the person with 30 points now has a minimum bid of 3.
Should a second player reach 30, the total bids in the hand should equal to 12.
Note: Missing a bid of 5 tricks will result in losing 10 points, as per the table below.
The player that wins the trick gathers the cards up into their pile and leads next.
If there is any type of communication with a partner before the hand has been given out, the other team may declare a reshuffle.
If any communication is performed during the games, the team that communicated with each other will receive an automatic break for both partners and the receiving team will be allocated the points they initially called for, even if they were going to break.
The illegal communication includes talking about previous past or future plays.
Missing a contract results in losing 1 point for each trick bid.
In addition, bidding for a higher number of tricks results in a higher value of points, as follows: One of the players is the scorer and writes the bids down, so that during the play and for the scoring afterward, this information will be available to all the players.
