The New Tetris is a puzzle video game for the Nintendo 64.
 The game was developed by H2O Entertainment and published by Nintendo, based on the latter's popular "Tetris" series.
 The game was originally released on July 31, 1999, in North America.
3D Tetris is a puzzle video game developed by Technology and Entertainment Software and published by Nintendo.
 It was initially released for the Virtual Boy on March 22, 1996, in North America only.
 The game allows players to control multiple falling blocks, rotating and positioning them to clear layers in a "Well".
 The game is similar to other Tetris games, but uses a three-dimensional playing field as opposed to the traditional two-dimensional view.
 The game contains multiple modes and gametypes, as well as different difficulty settings and levels, which change different aspects of the gameplay.
The bishop and knight checkmate in chess is the checkmate of a lone king which can be forced by a bishop, knight, and king.
 With the stronger side to move and with perfect play, checkmate can be forced in at most thirty-three moves from any starting position where the defender cannot quickly win one of the pieces.
 The exceptions occur when (1) the defending king may be forking the bishop and knight so that one of them is lost on the next move, or (2) the knight may be trapped in a corner by the defending king and the knight is lost in one or two moves, and the position is not in the "stalemate trap" (see below).
 These exceptions constitute about 0.5% of the positions.
 Checkmates are possible with the defending king on any square at the edge of the board, but can be forced only from positions with different material or if the defending king is in a corner controlled by the bishop or on a square on the edge next to a corner, but mate adjacent to the corners not controlled by the bishop is only two moves deep (with the same material), so is not generally encountered unless the defending side plays inaccurately.
 Although this is classified as one of the four basic or elementary checkmates (the others being king and queen; king and rook; or king and two bishops against a lone king), it occurs in practice approximately only once in every 6,000 games.
Castling is a move in the game of chess involving a player's king and either of the player's original rooks.
 It is the only move in chess in which a player moves two pieces in the same move, and it is the only move aside from the knight's move where a piece can be said to "jump over" another.
A block is a defensive tactic in chess in response to an attack, consisting of interposing a piece between the opponent's attacking piece and the piece being attacked.
 This type of blocking will only work if the attacking piece is a type that can move linearly an indefinite number of squares such as a queen, rook, or bishop and there is at least one empty square in the line between the attacking and attacked piece.
 Blocking is not an option when the attacking piece is directly adjacent to the piece it is attacking, or when the attacking piece is a knight (because knights "jump over other pieces" and cannot be blocked).
 When an opponent's attack on a piece is blocked, the blocking piece is to some extent pinned, either relatively or absolutely, until a future move by either side allows it to be unpinned.
Tetris 2 (known in Japan as Tetris Flash Japanese: テトリスフラッシュ ) is a video game published in 1993 and 1994 by Nintendo for the Game Boy, Nintendo Entertainment System and Super Nintendo Entertainment System.
Knight Move (ナイト・ムーブ ) is a puzzle-platform game created by Alexey Pajitnov (the creator of "Tetris") for the Famicom Disk System in 1990.
 A similar but notably different game by the name of "Knight Moves" (note that "Moves" is now plural) was released in 1995 for Microsoft Windows.
A hippogonal (pronounced ) chess move is one similar to a knight's move.
 That is, a leap "m" squares in one of the orthogonal directions, and "n" squares in the other, for integer values of "m" and "n".
 It need not be a 2:1 ratio for m and n.
 A specific type of hippogonal move can be written "(m,n)", usually with the smaller number first.
Tetris (Russian: Те́трис , pronounced ] ) is a tile-matching puzzle video game, originally designed and programmed by Russian game designer Alexey Pajitnov.
 It was released on June 6, 1984, while he was working for the Dorodnitsyn Computing Centre of the Academy of Science of the USSR in Moscow.
 He derived its name from the Greek numerical prefix "tetra-" (all of the game's pieces contain four segments) and tennis, Pajitnov's favorite sport.
Knight Moves is a puzzle video game released for Windows in 1995.
 It is based on a similar game, "Knight Move" (note that "Move" is singular in this version) created by Alexey Pajitnov of "Tetris" fame, though he had no part in the creation of this game.
