The difference between Tangram and Tetris

The difference between Tangram and Tetris is that Tangram has only seven chessboards, and even if the game is over, Tetris chessboard is infinite, and theoretically it can be played indefinitely.

Tangram is an ancient traditional intellectual toy in China. As the name implies, it consists of seven boards. And these seven boards can be put together into many figures. The basic rule of Tetris is to move, rotate and place all kinds of squares automatically output by the game, so that they are arranged into one or more complete lines, and the scores are eliminated.
