TETRO CLASSIC - FREE ONLINE GAME
As you have probably gathered by the game title, Tetro Classic is a HTML5 online version of the classic game Tetris which can be played on all devices. If you've never played the game (You obviously didn't own a Game Boy) before then this next paragraph will be useful to you.
How To Play
Drop down and rotate the falling coloured blocks to complete horizontal lines of the same colour. When a line is complete, it will disappear from the screen, making the stack smaller. If the stack of blocks reaches the line at the top of the screen then the game is over. If your on a PC or Mac then click the arrow keys on the screen with your mouse or use the arrow keys on your keyboard to move and rotate the blocks. On a mobile device simply touch the arrow keys with your finger.
Up arrow = rotate block and the other arrows move the block left, right and down.
