basic rules Numerous further variations to the basic rules may occur, and only a few examples can be mentioned here: Certain games require the holder of a certain card value to play it as the lead to the first trick of a hand; Hearts, as commonly played in North America, requires the player holding the 2 to play it as the lead-off card. Variants of Pinochle sometimes require the first player to the left of the dealer that holds a dix (9) to lead off. There may be restrictions on leading certain suits; a common Hearts rule is that a player may not lead a Heart until at least one trick has had a Heart played off-suit to another trick. Spades has a similar but less-common variation regarding its trump suit. There are trick-taking games played with Domino tiles instead of playing cards. These include the Chinese Tien Gow and Texas 42. Giog is played with Chinese chess tiles. Many games are played with one or more stripped decks (a deck from which certain card values are removed). The most common stripped deck is a piquet deck, used for piquet, Belote, Skat, Euchre, Bezique and (with two piquet decks) Pinochle, among others. Rook's main variant, Kentucky Discard, uses the equivalent of a 52-card deck with all card values 2–4 removed. Most regional Tarot variants, especially Central European and Italian variants like Tarock and Tarocco, use some subset of the "full" 78-card Tarot deck. In Bridge the partner of the contractor or declarer is called dummy and does not actively participate in the play; dummy's hand is instead laid on the table face-up after the opening lead, and declarer chooses the cards from dummy's hand to play during dummy's turns. In Hachinin-meri and Truf, trumps are played face down. When the trick is finished, the trumps are revealed to see who won the trick. In many trumpless games that do not require following suit, sluffing is done face down. This is done in Madiao, Tien Gow, Tam cúc, Six Tigers, Ganjifa, Kaiserspiel, and Brazilian Truco. Some cards lose their trick-taking power if they are not led or played in a specific trick as in Karnöffel, Tien Gow, and Ganjifa. In tarot games played outside of Central Europe, the Fool is a special card that excuses the player from following suit. Except in rare circumstances in some games, it can neither capture
