Did I say Tetris? I really should have said Blockfall. Yeah it is another Tetris-clone that you can run from within Firefox. Unlike most games you can run inside the browser itself, this one is really addictive! Need a break from surfing the Internet? Then all you need to do is install this Firefox plugin and get ready to get your block on!

Blockfall has a few simple rules, if you have never played Tetris before. You need to get rows of blocks to fill up all the way across the window. Once you do, they will be cleared out and more blocks will fall. You keep doing this over and over till you run out of room in the window, or your fingers go numb.

The neat thing about Blockfall is you are not stuck with your average square colored bricks falling down in the window. You can change them to triangles for an even harder challenge. You can also change them to hexagonal blocks for a real workout. You can control the blocks by hitting the arrow keys and pause the game with the “P” key. Anything else you need to do, I am pretty sure you can figure out on your own.

So have some fun for a change! We all need a break from what we are doing, and what better way to waste time than with Tetri.. I mean Blockfall!
