Freebie Fridays have been somewhat of a tradition over at NimbleBit, where they make one of their games free for a day to promote a new title or the rest of their lineup. In a somewhat unprecedented move, they've decided to make all of their games free for a day to promote their new project, App Classics, a web site that searches the App Store using various calculations in attempt to generate a list of the best and most popular apps available.

If you're unfamiliar with NimbleBit's collection of games, here is what's available for free that would have cost you a buck or two yesterday (and will tomorrow):

• Bluebird – Play as a small bird trying to fly as far as possible. Eat bugs to regain energy and tap the screen to flap your wings
• Hanoi Plus – A classic logic puzzle, move stacks of differently sized baskets to the opposite side of the screen stacked smallest to largest.
• Moon Drop – Assist astronauts colonizing the moon. Tap and hold the screen to fire the thrusters of the lunar landers to help them land safely.
• Scoops – Catch falling scoops of ice cream as high as you can while avoiding tomatoes and onions. Play long enough and you will be stacking ice cream past the planets of our solar system.
• Sky Burger – Fill orders for burgers utilizing ingredients falling from the sky. Gameplay is similar to Scoops, but with objectives.
• Textropolis – Search for words using the letters of various city names. With each word match the definition flies by and buildings are built on the top half of the screen.

A few games have gone on sale or even dropped to free over the past week.

iBlast Moki ($1.99 -> $0.99) – One of our Best iPhone Games of September dropped to $0.99 earlier this week and remains on sale. It remains a great value at only $0.99, with over 70 levels and online level sharing.

Topple 2 Plus+ (Free) – In celebration of the Plus+ network launch, Ngmoco has released a free version of Topple 2. In the game you stack blocks of various shapes and sizes to reach a set altitude goal within the provided time limit.

Dr. Awesome Plus+ (Free) – This Qix clone is also free. As Dr. Awesome, you must perform microsurgery to save your friends from a deadly virus. A fun game that's worth getting for free.

LucasArts' Secret of Monkey Island has been put on sale this weekend for only $3.99 (down from $7.99) [App Store].

Originally released in 1990, and having seen several revisions following the initial release including a port to the Sega CD, this Special Edition of The Secret of Monkey Island [App Store] is the best version of the game yet. It has been completely re-imagined with new art, complete voice-overs, and a new live instrumental musical score. The iPhone version really is an impressive effort.

The game has also seen a 1.1 update which fixes a number of 3GS related issues (graphics, crahes), audio bugs, and tunes the control acceleration and sensitivities.

The weekend always seems to bring some deals for you bargain hunters. Here are a few apps that have gone to $0.99 or lower. Game titles link directly to app store.

• Memovator ($0.99 -> Free) is nicely produced memory game where you act as the elevator operator and must remember the destination of everyone who gets in.

  There are 6 different unlockable levels. The game starts with regular numbers, but them moves on to roman numerals, chinese numerals, animal graphics, japanese kamon and time. The game is really well done but seems to get impossibly hard pretty quickly. But, if you've got a great memory, here's a game for you. And it's Free this weekend.
  

  
  

• Match 3D Flick Puzzle ($3.99 -> $0.99). Many people seem to be loving this Match-3 variant. Instead of the usual 2D grid, PlayScreen put their Match-3 on a rotating 3D cube. A Lite version remains available [App Store] to try.

• KIL.A.TON ($2.99 -> $0.99). A solid artillery game we reviewed in August. The level of content and the organization of the different game modes including online multiplayer are very entertaining.

• Fastlane Street Racing ($3.99 -> $0.99). One of the early iPhone racers that we really enjoyed. Fastlane has since been eclipsed by some of the big racing titles, but still remains a good value at only $0.99.

Ngmoco's Rolando 2 has seen its first price cut down from $9.99 to $5.99.

Rolando 2 received high marks in our own review as well as the TouchArcade community.

All in all, we are really impressed with Rolando 2 which does justice to one of the few classic iPhone originals. Like the original, the art, style and music come together in a wonderfully immersive package. And with the addition of Plus+, you'll find yourself working to perfect your scores on individual levels in order to challenge your friends.

Rolando 2 is expected to receive free level pack updates ahead of Rolando 3 which was also announced in March.

App Store Link: Rolando 2, $5.99

We mentioned this in our previous sales update, but Firemint's Real Racing has now dropped its price from $9.99 to $6.99 and is expected to remain there for this weekend only.

Real Racing is considered one of the most technically impressive racing games on the iPhone. We reviewed it back in June and loved the great controls, intelligent AI, and its technical achievements.

The game has since been updated with 6-player local Wi-Fi multiplayer, new cars, new career modes, and control options.

App Store Link: Real Racing, $6.99 (Weekend sale)

Here are a few interesting sales over the past couple of days:

• Silent Hill: The Escape ($7.99 -> $0.99) – Konami's first person shooting game set in a creepy environment has seen a massive price drop from $7.99 to $0.99. So, if you've been curious about this title, now's a good time to try it.
• Resident Evil 4 ($7.99 -> $2.99) – The mobile edition of Resident Evil 4. There was some very split opinions between those who loved the game and those who felt it paled in comparison to the original console version. Regardless of your position, a $5 price drop certainly makes it easier to pick up.
• Dirt Moto Racing ($4.99 -> $0.99) – A solid off-road racer that's easily worth $0.99.
• Crash Bandicoot ($5.99 -> $2.99) – One of the original kart racers for the iPhone, it seems they are starting to feel the pressure with Konami's Krazy Kart Racing and the upcoming Shrek Kart.

And, we've heard of one major game that will be holding a sale soon. Firemint's Real Racing [App Store] will see its first sale this weekend dropping from $9.99 to $6.99 temporarily. The sale should be live by Saturday morning, so keep that in mind if you've been holding out.

Four noteworthy games went on sale today including two from App Store giants. If you've been holding out waiting for a price drop on these titles, here's your chance.

Rolando, $5.99 -> $2.99 / Lite – A game that should need no introduction, Rolando is a puzzle/adventure game developed by HandCircus and published by ngmoco. Gameplay involves tilting the iPhone to move the various rolandos around Rolandoland. Different rolandos have different abilities that all must be used together as a team to make your way through the various puzzles of each level which often hinge on interactive objects like platforms and catapults. Featuring a soundtrack by Mr. Scruff, a ton of new levels added to celebrate the release of Rolando 2 [App Store], and nearly universal praise from the iPhone gaming press, now is a great time to pick it up.

Super Monkey Ball, $5.99 -> $3.99 – As an App Store launch title, Super Monkey Ball has been around forever. Featuring 110 levels starting off easy and eventually graduating to nearly impossible, Super Monkey Ball includes enough content to keep you busy for quite some time. If you're a fan of the series, or like ball rolling games with tilt controls, Super Monkey Ball is worth a look, especially at the sale price.

Boulder Dash Rocks, $4.99 -> 99¢ – A modernization of the Boulder Dash concept. While we had some reservations about some of the artwork and strictly timed nature of gameplay, at only $0.99 it represents a very high quality production with great controls. Boulder Dash Rocks is an action puzzler in which you play the earth digging Rockford who must collect a quota of diamonds to pass each level. Unlike the original game which relied on fast-paced joystick responses, Boulder Dash Rocks seems more suited for mobile / iPhone play.

Ynth, $2.99 -> 99¢ / Lite – A unique iPhone puzzler, Ynth allows you to take command of a small bug who must rotate a box across a marshland without meeting an untimely demise to the plethora of obstacles between the level start and the goal. Controlled with simple on screen buttons, most of the levels require a bit of trial and error to solve. At 99¢, Ynth is worth a look if you're in the market for a colorful brain teaser.

As if you needed one more difficult decision to make today, you can now either get a Subway $5 foot long sandwich, or five games that all have recently been dropped to 99¢. As strong as the allure of the meatball sandwich is, given the original price of some of these games, now is the time to buy if you've had your mouse hovering over the buy now button in iTunes in the past.

Castle of Magic, 99¢ – A really neat platformer by Gameloft, Castle of Magic has a level of detail seldom seen in iPhone games. Fun level designs, cool boss encounters, and a magical game world make for a highly enjoyable game. There is a down side to the amount of visual flair in the game, as Castle of Magic does have significant load times on older devices, so you might want to check out Castle of Magic Free [App Store] first.

Rise of the Lost Empires, 99¢ – Gameloft's real-time strategy game that takes place in a fantasy setting with two included campaigns, one for both orcs and humans. Colorful graphics and loads of voice overs make for a pretty fun game, but if you're the kind of person who sits down and plays through entire games in one sitting, Rise of the Lost Empires can be beaten in a matter of hours. If you're more of a casual player who plays games in small burts, the game should keep you busy for quite a while. Rise of the Lost Empires Free [App Store] is also available if you want to get an idea of how the game plays before purchasing.

Smiles, 99¢ – If you have room on your iPhone for another match three game, Smiles has more variety in it than most other similar games. Featuring 14 different game modes and 3 themes, Smiles has been well received by the iPhone gaming community and was even a finalist for the best mobile game at the Independent Games Festival Mobile Awards. If you want to see what all the fuss is about, Free Smiles [App Store] will let you get your feet wet.

Silent Scope, 99¢ – Originally a awesome arcade game, Silent Scope for the iPhone has the same wacky premise of you playing as the world's top sniper trying to rescue the President and the first family from terrorists. The controls make some of the boss encounters and tracking moving enemies fairly difficult, so the $5.99 original price point was hard to swallow because of that. At 99¢, Silent Scope is worth a try if you've found yourself enjoying the other sniper games on the App Store.

Power Touch Pros, 99¢ – An immensely popular series in Japan, Power Touch Pros is an arcade baseball game with a ridiculous amount of customization to it. You can play exhibition games, entire seasons, change the overall difficulty, enable or disable errors, and even change whether or not there is wind in the game. Gameplay can be as simple as tapping or extremely complex depending on how far you delve in to the options available.

A little late to the all out price slashing fiesta we saw last week, EA has since dropped the prices on a few of their games this afternoon.

Need For Speed Undercover, $6.99 -> $4.99 – A mission-based racing game that had an insanely long development cycle that produced a game that was well worth waiting for. While Need For Speed Undercover runs great on previous-generation devices, it's on the short list of games you really should have if you want to stretch the graphical legs of your iPhone 3GS. At the higher framerate, the sensation of speed is even better. We enjoyed the game in our review, and along with Real Racing [App Store], Need For Speed is still one of the best full 3D racing games on the App Store.

Wolfenstein RPG, $4.99 -> $2.99 – Originally produced by Id Software, ported to the iPhone by Firemint, and published to the App Store by EA, Wolfenstein RPG is a high-resolution adaptation of a J2ME game. The game puts a silly spin on the Wolfenstein universe and provides slow-paced turn-based combat originally designed for the user input constraints of a typical cell phone. Firemint did a wonderful job on the port, and as I mentioned in our review, as long as you're not expecting a fast paced shooter, it's a good time.

The Sims 3, $9.99 -> $6.99 – The latest mobile iteration of the Sims dynasty of video games, The Sims 3 is a fun, albeit watered down version of the original. Build mode is lacking in the iPhone version, so you are really limited in how much you can customize your house. Regardless, as we said in our review, if your favorite things about Sims games was cultivating relationships with other Sims, the iPhone game is great. If you liked tweaking your house and building Sim torture chambers, the iPhone game doesn't have much to offer.
