While this week has been filled with news and reviews of fast paced games, I've always had a weakness for word games on the iPhone, even though I'm fairly terrible at them. Here are three recently released or recently updated word games that are all worth checking out–

Guess the News [99¢ / Free] – Surprisingly enough, the news is good for more than material to auto-tune. Guess the News pulls news stories down from various RSS feeds, and turns them in to puzzles to be solved. You're given a brief description of the article, then need to guess the headline from the pile of letter tiles on the game board. Puzzles are broken out in to several categories such as health, sports, and even "odd stories". For instance, I recently played a few games in the technology category that had me guessing the titles of Engadget posts. Guess the News features three difficulty levels which control how much of the headline is already completed at the start of each puzzle, and with the dynamic content fetching provides infinite replay value.

Word Spin [$1.99] – As seen in the above trailer, this game has two parts to it, the first stage amounts to rotating and positioning the various wheels loaded with letters to line up as many words as possible. You then tap the top of the screen to lock the wheels in place, then find every word you possibly can as you rotate the locked set of word wheels searching for valid words. Once you get good enough, you can compete both against friends by sending email challenges where they will play against your exact configuration of the word wheels or by submitting your score to the global online leaderboard. The gameplay mechanic is solid and provides an interesting spin (See what I did there?) on the word hunting game formula.

Words With Friends [$2.99 / Free] – Everyone who owns an iPhone or iPod Touch should have either the free or paid version of this game on their device. Words With Friends takes the game of Literati (a variant of Scrabble) and adds excellent asynchronous online multiplayer with recently added push notifications that alert you when it's your turn in any of your active games. The free version is ad supported, but otherwise fully featured, and according to a recent presentation by the developers at GDC Austin, Words With Friends and Chess With Friends [$2.99 / Free] has 50,000 active users daily.

I've had numerous Words With Friends games going for months now with nearly every friend of mine who owns an iPhone, a clever in-game search function will search the Words With Friends player database for friends of yours you want to start a game with, and if the game can't find them it will offer to send them an email invitation. Everything about the game is implemented so amazingly well that you owe it to yourself to at least try the free version if you're even remotely interested in word games, especially with the recent update adding push notifications. If you need people to play with, stop by the Words With Friends thread on our forums.

Riptide Games has released the first game that was the product of the 360 iDev Game Jam. The Game Jam was an all night coding session for developers to try to create a game in 10 hours. This particular game was created in conjunction with Jonathan Hartstein of Pyro Monkey Productions and Eric Lannan of Crucial Games.

Gravity Sling is an inertia based puzzle game, where you must try to get the astronaut back to the space shuttle safely. In order to do this you'll need to take advantage of gravity from the nearby planets as you sling the astronaut through space.

Here's a promotional video showing how the game is played:

Rather than releasing the game at the expected $0.99 price point, Riptide games has taken advantage of Apple's new policy allowing games to be distributed for free with the ability to purchase additional content. 15 levels are included in the free version, with 30 additional levels available in-app for $0.99. This eliminates the need for a Lite version and could be a peek into how things may evolve in the App Store.

TipCat Mobile just released a very nice side scrolling shooter called Cell War [App Store].

The $2.99 game offers a beautifully stylized side scroller that places you as the pilot of a nano machine whose mission is fight off viruses and save the humans from disease. Designed for the iPhone, the game has some nice touches with a good variety of level design and power-ups that seem to keep the game interesting. Three levels of difficulty are provided over 9 different stages, and the game also provides online leaderboards.

The game is controlled primarily through the use of the iPhone's accelerometer allowing you to move the ship with tilt controls alone. This can be calibrated in the options so you can choose the neutral position. Your primary weapon is fired automatically and can be upgraded multiple times. Beyond this, the game also offers a nice touch targeting system for missiles akin to Space Deadbeef — simply touching on the enemies will lock on your missiles.

Here's the game in action:

The developers have also released a fully featured Lite version that provides the first two stages of the game, complete with all 3 difficulty levels. There really is a lot to like about this game, and the production values are outstanding. My only real issue with the game may simply be a personal one. I've never been a fan of the use of the accelerometer for ship movement in 2D iPhone shooters, and I much prefer touch (which is not an option). If you have no such hang ups, this game is definitely recommended, but even if you do, the Lite version provides you with a great sampling of the game.

We felt somewhat obligated to review a game as huge as Eliminate Pro [App Store]. Following its epic development cycle, it's hard to think of many other games which were as highly anticipated among our community. But it's not just Touch Arcade forum members who have been waiting for Eliminate, as countless other developers have all been anxiously holding their breath to see how successful the microtransaction-powered gameplay is from a business perspective.

If it wasn't apparent by now from reading our other coverage on the game, we really enjoy Eliminate. The classic four player deathmatch gameplay is enhanced with an RPG-style progression system which adds a great deal of depth to an otherwise simple game. Power-ups littered throughout the maps spice up battles, and when it's working as intended, the matchmaking system seems to do a decent job of making sure the game you get thrown in to is reasonably matched.

While we did feel obligated to review Eliminate Pro, since you can download and experience everything in the game for free, there isn't much reason for me to dwell much on the gameplay. Instead, I'll try to clear up some common misconceptions I've seen in comments and in forum posts, along with offering some helpful tips and hints for new players.

Eliminate [App Store] has been somewhat of a sensation on our forums since its initial release in Canada. Our Canadian members (as well as quite a few "Canadians") have really enjoyed having early access to the game, and aside from the somewhat expected reactions towards the energy system and in-game microtransactions, it seems like everyone is having a lot of fun.

We extensively previewed Eliminate last month, and very little has changed since then short of some tweaking of the energy system and increasing the recharge time. Still, as mentioned in the preview, you can play Eliminate for as long as you'd like to without paying a penny– Your character advancement will just be slowed as you will only earn credits (the in-game currency used to level up and buy equipment) while you're energized.

I highly recommend downloading Eliminate. It's free, you've got nothing to lose. Regardless of how you feel about the payment system ngmoco is using to fund the game, it's still one of the more impressive multiplayer games available on the platform, and experiencing that won't cost you anything.

Update: Eliminate is available in most major iTunes markets, it seems there are still some countries that haven't seen it yet, but most European stores as well as the US store are currently stocked with Eliminate.

RetroVenture has released a port of the old 1982 Apple II game Transylvania. Originally developer by Antonio Antiochia, RetroVenture has collaborated with the original author to bring this classic game to the iPhone.

In Fall 2009, Roe Mobile Development will release Transylvania for the iPhone. Transylvania is an adventure game that was originally released for the Apple ][ in 1982. Back then it was quite successful and spawned two sequels (Crimson Crown and Vanquish the Night: Return to Transylvania). The iPhone version is a joint work between Kenneth Roe and Antonio Antiochia who is the original author. The iPhone version will add a new touch interface and sounds.

If you ever played the original version, here's your chance to get it again for free. Even if you miss the Halloween sale, the game will be available for only $0.99.

After an amazing amount of anticipation on our forums, Eliminate is finally playable for our Canadian friends. Like we mentioned in our previous post, ngmoco is using this initial Canadian launch as a large-scale beta test to guarantee the servers hosting the game are running as well as they should be when Eliminate is finally released in to the wild. Things are still being tuned and tweaked, so I'm reluctant to offer many gameplay specifics as ngmoco indicated to us that quite a few elements of the game are going to be in flux while they make their final adjustments.

What I am willing to say is that playing Eliminate with real people is every bit as awesome as I imagined it being. The last time I had played the game was for our hands on preview we posted earlier this month. So far I've yet to notice any major differences, so everything mentioned in our preview is still accurate short of the energy recharge period which ngmoco says still has not been finalized.

So far the Canadian beta has been lag free, and I've always been able to find a game almost instantly. One of the things I've been dying to find out is how Eliminate performs over 3G, and so far it seems to play just fine. Already the Plus+ leaderboards are filling up as more and more people download and install the game, and I can't wait to see how many people are online tomorrow.

Even in its current beta status, Eliminate is receiving rave reviews on our forums and has seemed to ether meet or exceed the expectations of nearly everyone lucky enough to have a Canadian iTunes account. We have our fingers crossed that the beta goes smoothly and quickly, and as soon as the game is officially released worldwide we will post an in-depth look at the game.

Ngmoco's widely anticipated titles Eliminate and Touch Pets have both been approved by Apple for inclusion in the App Store. Ngmoco announced tonight that both titles will be free to download, but that will see an initial launch in Canada before spreading to the rest of the world.

The reason for the beta Canadian-only launch is to make sure they have enough server capacity to handle the load for the worldwide launch.

Official threads for Eliminate and Touch Pets have been started in our forums:

- Eliminate – FREE 4 Player Online FPS: LIVE IN CANADA
- Touch Pets Dogs – FREE social puppy game: LIVE IN CANADA

The games have not quite yet propagated into the Canadian App Store but we'll post the direct links here when they do.

If you've found yourself with nothing to do today aside wait for Halloween tomorrow, the Edis brothers of Ezone.com have offered a small amount of relief in making their latest game free for the day. Scarecrow [App Store] is a simple jumping game similar to Doodle Jump and other games with the sole goal of seeing how high you can go.

We explained the game in more detail in our review last month:

ike their predecessors, the scarecrow wishes to go high… very high. Instead of jumping on platforms, however, scarecrow is propelled by popping kernels of corn. Make sure to hit enough of them as you ascend to keep your momentum going. Hitting the explosive corn also recharges your own personal boost that can be triggered by tapping on the screen. This supply is limited so you need to use it sparingly.

Your path is hindered by a number of obstacles including chainsaws, spikes, and more that threaten to dismember you as you ascend. You can take a fair amount of damage to where you are just left with a torso flying upward.

We enjoyed Scarecrow in our review, and played it enough that we included it in our recent Halloween games roundup. So what are you waiting for? It's free, and it has Plus+ with high score tracking and Push challenges. There's not much reason to not give the game a try.

Early this month Empty Clip Studios gave us an exclusive preview of the upcoming iPhone port of their download / retail Wii rhythm puzzle title, Groovin' Blocks. Those anxious to get their hands on this one can now try the full [link] or lite [link] version, which went live in the App Store yesterday.

Each of Groovin' Blocks' 50 levels is played to a pumping techno soundtrack with scrolling beat-indicators on either side of the screen.  Block clusters slide onto the playfield in a Tetris-like fashion, and will ultimately come to rest at the bottom of the screen.  A tap on the 'drop' button will quickly drop the piece into place — but if you "hit a beat" (tapping the drop button during a beat of the soundtrack) the blocks will be bigger, brighter, and worth more points.  Hitting consecutive beats without a miss increases your score multiplier — but miss a beat and it drops back to zero.  Hitting the occasional Superbeat, shown brighter in the scrolling beat display, will double your current score multiplier.

Certain blocks contain power-ups that can be collected only if you hit a beat when placing said block.  Power-ups are unleashed when the successfully placed block is destroyed by a match-three scenario.

See our preview video for a closer look.

GameSpot calls the Wii version of Groovin' Blocks "a music-based game like no other."  As we said in our preview look, there's no shortage of match-three puzzlers in the App Store, but Groovin' Blocks' musical / rhythm component really does set it apart from the pack.
