It sounds simple enough - all you have to do is make lines of tetris
blocks! But you may find it's harder than it sounds!
Left Arrow Key: Move block left
Right Arrow Key: Move block right
Down Arrow Key: Move block down
Up Arrow Key: Rotate block
'P' Key: Pause game
Only compatible with Internet Explorer 4-10 (at the highest -- it doesn't work in 11, but I may have missed if it packed up in an older version -- please tell me by providing Feedback using the link at the bottom if it does not work in a browser version in that range)
Came here through a bookmark or search engine? Then you need to know that there's a new version of Tetris available here - it works in more browsers, remembers your high scores, and has multiple levels!
