TETRIS               This Java applet implements the famous game Tetris invented by Alexey Pajitov. I would like to thank the people that help me, through their remarks and their skills, to develop this applet. To start, you just have to click on the applet. For those who do not know the game, the aim is to put the parts so it makes full rows that are instantly destroyed. A little difference with the original game: the difficulty level of the game is represented by a lightly violet row. If you destroy a row below this boundary, you win more points. But you take the risk that a row may be randomly added at the bottom of the game. Be patient at the beginning, it takes some time to download the applet. What is the best strategy to play ? The site Learning to play Tetris proposes a learning method for the computer based on quality criteria of the game.
