Rules and Variant Intros Below:

1. Bughouse:

Bughouse is a variant of chess played by four players in teams (partnerships) of two on two separate chessboards. Each partner plays an opposing team member with the goal being to win the game by normal means (checkmate or timeout). One partner plays Black, the other White. Partners help each other by capturing enemy pieces which their partner may then place (drop) on an empty square on their turn. (Click here for Tips for Beginners)

• When you capture one of your opponent's pieces, it is immediately passed to your teammate's "piece bank" for him or her to use at their discretion.
• On any turn, instead of making a move, a player can "drop" any piece from their "bank" to any open square on the board.
• Pawns may not be dropped on the 1st or 8th ranks.
• A pawn that is placed on the 2nd rank may move two squares on its first move, as in standard chess.
• Pawns that have promoted and are then captured go into the "bank" as pawns, not as the piece to which they promoted. Such promoted pieces are called "counterfeits."
• Draws by agreement are not supported, but draws by repetition can occur.
• A bughouse game is over when a game on either board ends in checkmate, resignation, or timeout.

2. Crazyhouse:

Crazyhouse is a variant which follows most of the normal rules of chess, except that captured pieces can be reintroduced to the board on your turn. (Crazyhouse Tips for Beginners coming soon!)

• The pieces move the same way that they do in traditional chess.
• Games can still end in the same way: checkmate, stalemate, and time-out.
• Captured pieces reverse their color and are added to the capturing player's "bank."
• On your turn, instead of making a move ,you may choose to "drop" a piece from your "bank" onto any open square on the board.
• You can drop a piece from your bank to block a check, even in a position that would otherwise have been checkmate (i.e. without the piece from your bank to drop).
• You may drop a piece to both check and checkmate the enemy king.
• Pawns may not be dropped on the 1st or 8th ranks.
• Pawns that have promoted and are then captured go into the bank as pawns, not as the piece they promoted to.

3. 3-Check:

3-Check is a simple variant with one clear task in mind: Check the king as many times as you can! Normal rules apply, but you can also win (or lose!) a game by checking (or getting checked) 3 times in total. (3-Check Tips for Beginners coming soon!)

• Games can still end in the traditional ways of checkmate, stalemate and time-out.
• The game can also end if a player checks their opponent's king three times.
• A move that results in a double-check only counts as one check towards the "total check score."

4. King of the Hill:

King of the Hill or "KOTH" is an exciting variant in which the goal is to get your king to the center of the board or "top of the hill". (King of the Hill Tips for Beginners coming soon!)

• Games can still end in the traditional ways of checkmate, stalemate and time-out.
• The game can also end when a player moves their king to any of the four central squares.
• e4, d4, e5, and d5 are "top of the hill" squares, winning the game on the spot for either White or Black, regardless of the nature of the position.

5. Chess960 (Fischer Random):

Chess960, or Fischer Random, is a variant invented by the late World Champion Bobby Fischer. The rules of the game are the same as standard chess, but in an effort to reduce the impact of opening theory, the pieces have been randomly shuffled on each player's back rank. (Launch a challenge to play a chess960 game). 

• Games end in the traditional ways of checkmate, stalemate and time-out.
• Bishops must still be on opposite colors in the initial Chess960 position.
• The king must be between the rooks to maintain the ability to castle both ways. That means a king can only be placed between the squares b1 and g1 or b8 and g8 for Black.
• This means:
  • No matter the location of the king and rook, standard rules of castling apply. It must be the first move for both king and rook, the king may not travel into or through check, and there may be no pieces on any square that either piece travels through.
  • The king and rook end the process of castling where they would in a standard chess game. Example: Even if a white king is on b1 and a rook is on e1, castling kingside would involve dragging the white king to g1 (its final destination square), which will automatically move the white rook from e1 to f1, as White will always have the king on g1 and the rook on f1 in the final castled position.
