Recently we took a look at three of my favorite online games. Now I’m going to take a look at Testrisk, a site that lets you play a bunch of different versions of one of my absolute favorite games, tetris. And best of all? They are all free to play! Pictured above are four of more than eighteen games that they offer, including (starting at the top left) Original Tetris, Boom Box Tetris, Simpsons Tetris, and Funny Tetris.

The Original Tetris is as addicting as ever. It loads right up and you play with a mix of your directional pad and the spacebar. It gives you three options for difficulty, the traditional easy, medium and hard. I can play this game for hours and hours.

Boom Box Tetris is a futuristic version of Tetris where blocks with four colors fall and you have to match up the colors by spinning the boxes around. In addition to the colors, you’ll occasionally get boxes with countdowns that explode and take out the blocks around them. There is a box that shows you your “Boom Power” percent. There is a variety of music you can scroll through while you play. Overall this is a much more in your face tetris game.

Simpsons Tetris is just like the original Tetris game but it is themed with the long running Fox animation. The game play is normal, but the box is a bit smaller than regular which can be a little annoying.

Funny Tetris is a bit silly. Instead of shapes you have little cartoon guys that stack up. You need to match the characters together to make lines, but it is really distracting. None of the text is in English, which slightly complicates things. Overall, it is a lot of fun and very different than I’m use to.

Other Tetris game options include Diamond, Stuck Up, Phit, Sonic, Mario, Egypt, 3D, and Jellytris. I’m sure that you will find the right game for you, and best of all, it is always free!
