Quinn is a free Mac-style Tetris (ever heard of it?) clone with a few tricks up its sleeve. Aside from it's smooth, clean interface, Quinn offers customizable keyboard controls and downloadable custom backgrounds and piece styles.
Quinn's key feature is network multiplayer (via the Internet or locally through Bonjour), and there are multiple ways to determine a multiplayer winner: highest total score, highest score reached, longest play time, and most lines-per-minute.
When we checked the list of Quinn servers on the developer's site there were only 2 people playing on the Internet, so you may want to stick to networked Bonjour play with your office mates. If you are looking for strictly Internet-multiplayer Tetris, try Blockles.
Multi-player Tetris not your cup of tea? How about a shot of espresso then? Tetrical is an online Tetris-style game that adds a whole new dimension of complexity. Literally.
Tetrical is a browser based game that's basically a 3D version of Tetris. If you're pretty good at Tetris there is no guarantee you will be good at Tetrical, as it takes a while to get used to the 3D environment, And to make matters worse, some of your blocks have weird 3D shapes.
Of course, Tetrical is hardly the first 3D version of Tetris around. We remember playing Blockout back in the 80s. Fortunately, no classic game ever seems to go uncloned. If you're looking for a Blockout-style game to play in your web browser while your boss's back is turned, you might want to try 3DTRIS. The controls feel a bit more intuitive to us than Tetrical's, but that might be years of muscle memory kicking in.
Think you're pretty good at Tetris? Well playing against a computer is one thing, but how do you think you'd fare playing against other hard-core Tetris players? Blockles is an on-line competitive Tetris-clone from the makers of online dating site i'minlikewithyou. And it's the quickest way we're aware of to find out if you suck at Tetris.
Gameplay is pretty much exactly what you'd expect. You use the arrow keys to rotate blocks and hit the spacebar to drop them quickly to the bottom of the screen. You can either join a game hosted by another user or create your own if you're a registered user. Matches can have just a few players, or as many as 8.
There are a few interesting aspects to the multiplayer gameplay. For example if you break two or more lines apart at the same time, each of your competitors will get a new line of blocks. That makes Blockles a bit more fast-paced than the original Tetris game, but also a bit more addictive.
Bloxorz is a game with a silly name, but great gameplay. While there are millions of puzzle games out there, few come close to matching the fun and challenge of Tetris. Though Bloxorz does.
Now, to be perfectly clear, Bloxorz is not a Tetris clone. In fact, the gameplay in Bloxorz couldn't be more different. The Tetris comparision is simply to point out that we think the game is that good, especially as a little web-based timewaster.
The hero of Bloxorz is, well, a rectangular block. Your job is to move the block by flipping it sideways or end-over-end through the maze of square tiles and arrange things so that your last flip slides your block through a single square hole. At first the game is a bit frustrating, but the learning curve is shallow and within 5 minutes you'll probably find yourself a few levels in, and having fun.
A few years ago you could impress friends by showing them a minesweeper clone on your PDA. These days, it's not unusual to see full-fledged PC or console games like Call of Duty 2 or Syberia ported to Windows Mobile.
But you don't have to spend a ton of money to turn your PDA into a gaming device. A few weeks ago we showed you five emulators that turn your Windows Mobile PDA into a pocket GameBoy or Playstation. This week, we showcase 10 great standalone games.
Solterra
First up is an amazing 3D space shooter called Solterra. This game is designed to run on Windows Mobile PDAs with an Intel 2700g graphics accelerator, so it's pretty much just for Dell Axim X50v/X51v users.
Solterra was developed as a commercial game, but later released as freeware. The rules are pretty simple. Fly your ship, blast anything that moves, and collect the thingamajigs you can pick up along the way to beef up your spaceships weapons and armor.
Tetris clones are a dime a dozen, but S-TRIS 2 is unique in two ways. One, it's free, and two, it's damn good. I found and tested it on my Pocket PC, but it turns out that S-TRIS 2 is available for a number of platforms, including Win32 (Windows), GP2X, Pocket PC, Smartphone, and Symbian. How cool is that?
In terms of game play value, S-TRIS 2 is right up there. The visuals are clean, quick and smooth, the sound effects are solid, and the controls feel responsive. It's a simple matter to remap the controls if you prefer a different layout - for example, I like to have the "fast drop" button be the center button on my keypad, and it took me all of about 15 seconds to make that happen. The game gracefully pauses if you have to turn the power off on your device, and starts up and shuts down relatively quickly.
Although it's a little late for Easter, it's worth mentioning that the popular Bit-Torrent client uTorrent contains an Easter Egg on the About screen. Simply hitting the 'T' key on
your keyboard while viewing the About window in uTorrent will show a very rudimentary but playable version of Tetris.
Unfortunately, it doesn't appear to keep score or speed up as game play goes on, but it's definitely useful as a
distraction when you need a moment to think.
Puzzle
Express is an interesting cross between Tetris and... something else. It's a great fast-paced Flash game that will
appeal to people who grew up with Legos. You're presented with a box—a boxcar, actually, hence the
"Express"—and your goal is to fill it with Tetris-like pieces that appear on a conveyor belt. The catch
is, you have to fill it up completely—no gaps—and within a time limit. Sometimes you're presented with two
boxcars side-by-side and must fill them simultaneously with pieces from the same conveyor belt. And did I mention that
if your conveyor belt fills up, it's game over? When you finish filling one box, it's whisked away and another one
rolls up. The game starts out easy, with just a few boxes per level, but of course that changes as you progress. Two
hints: One, there's a little red square in the lower left. That's a single (1x1) piece that you can use to fill pesky
holes, but you have a limited supply (this took me several levels to figure out). And two, save 1x2 pieces as long as
you can—you'll need them at the end.
