Tetriz - the Classic Game app for iPhone and iPad

Tetriz is new Version of old Classic Game Designed by DRC Infotech.

Tetriz is a Soviet tile-matching Puzzle Game.

Tetriz Game is a Popular use of Tetrominoes, the four-elements special case of polyominoes.

A random sequence of Tetriminos fall down the playing field (a rectangular vertical shaft, called the "well" or "matrix"). The objective of the game is to manipulate these Tetriminos, 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 Tetriminos to fall faster, and the game ends when the stack of Tetriminos reaches the top of the playing field and no new Tetriminos are able to enter.

All of the Tetriminos are capable of single and double clears. I, J, and L are able to clear triples. Only the I Tetrimino has the capacity to clear four lines simultaneously, and this is referred to as a "tetriz". (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.)

* Effect of Tetriz on the brain

According to research from Dr. Richard Haier, et al. prolonged Tetriz activity can also lead to more efficient brain activity during play. When first playing Tetriz, brain function and activity increases, along with greater cerebral energy consumption, measured by glucose metabolic rate. As Tetriz players become more proficient, their brains show a reduced consumption of glucose, indicating more efficient brain activity for this task. Even moderate playing of Tetriz (half-an-hour a day for three months) boosts general cognitive functions such as "critical thinking, reasoning, language and processing" and increases cerebral cortex thickness.
