Block Puzzle - Classic Edition for tetris app for iPhone and iPad
The greatest block puzzle game!
Classic Block are game pieces shaped like tetrominoes, geometric shapes composed of four square blocks each.
A random sequence of Classic Block fall down the playing field (a rectangular vertical shaft, called the "well" or "matrix").
The objective of the game is to manipulate these Classic Block, by moving each one sideways (if the player feels the need) and rotating it by 90 degree units, with the aim of creating a horizontal line of ten units without gaps.
When such a line is created, it disappears, and any block above the deleted line will fall.
When a certain number of lines are cleared, the game enters a new level. As the game progresses, each level causes the Classic Block to fall faster, and the game ends when the stack of Brick reaches the top of the playing field and no new Tetriminos are able to enter.
Some games also end after a finite number of levels or lines.
All of the Brick are capable of single and double clears.
I, J, and L are able to clear triples.
Only the Tetrimino has the capacity to clear four lines simultaneously, and this is referred to as a "tetris".
This may vary depending on the rotation and compensation rules of each specific Tetris implementation.
For instance, in the Super Rotation System used in most recent implementations,certain situations allow T, S, and Z to snap into tight spots and clear triples
