For all of you puzzle-craving aficionados, you'll be happy to know that the partial port of Simon Tatham's Portable Puzzle Collection series has released the latest version 3.0 beta 1 for the Nintendo DS. Even though its been a while since our last update on the game, the new beta version still includes the nine all-time favorite puzzle games (Tents, Dimonosa, Mines, Bridges, Light Up, Pattern, Net, Untangle, and Sudoku), with a few new features put in for added customization.

The biggest improvement of this ported puzzle series is its ability to support mp3 files while playing. To help manage your music files, the game also allows you to create your own player profiles, which allow you to customize your name, the mp3 folder, your favorite text color, your favorite language and your background theme.

Once the selected mp3 folder is set, it plays all the files in a queue and repeats itself when the last song is done. While you can only have one playlist, and no options for random shuffling of songs, perhaps these are possible updates that the developers could look into the future.

As always, take care when installing this homebrew especially since this is the beta version. If you're interested in downloading this brain-teasing homebrew, you can get it from the download link we've provided below.

People whose brains are feeling a wee bit lethargic due to the recent summer vacation may want to check out Brain Age 2: More Training in Minutes a Day for the DS. This brain stimulator is now available in video game stores and should save save many a lazy gamer's brains from feeling too sluggish during classes.

"The point of the original Brain Age was to jolt users' brains out of complacency by challenging them with a variety of fun activities," Said George Harrison, senior vice president of Nintendo's marketing and corporate communications.

Brain Age 2 now features 15 modes including simple exercises such as repeated subtractions, unscrambling letters to form words, and playing on a virtual piano among many other activities (many of them not seen in the previous game). Sudoku puzzles are also packed in Brain Age 2, just enough to jump start lazy minds.

If you happen to notice that kids younger than your age are smarter than you, then it's a good idea to plonk down a few dollars for this title. If you can afford a few more, then get that snazzy yin-yang themed DS along with Brain Age 2 as well.

The multi-million selling Brain Training series continues with More Brain Training From Dr. Kawashima: How Old Is Your Brain?, the second installment in the franchise. Featuring all new exercises and DS Brain Age Checks, this is set to challenge even the most trained brains as it launches across Europe late next month.

More Brain Training From Dr. Kawashima: How Old Is Your Brain? uses the same format as its predecessor. The game is held like a book and players use the touch screen and microphone features of the Nintendo DS. The popular numbers game Sudoku also makes a return in this new title.

The DS Brain Age Checks take on a new form in this title as players are tested on three randomly selected exercises such as old school classic Rock, Paper, Scissors which asks you to name the position to either win or lose against the object shown and Speedy Symbols which challenges your memory of symbols associated with specific numbers.

More Brain Training From Dr. Kawashima: How Old Is Your Brain? launches in Europe on June 29 for a suggested retail price of around €30 (GBP 20, US$ 41).

Where else can you play Sudoku with a martial arts twist? The best part is, it's going to the handhelds - PSP and DS. Zendoku promises some pretty interesting (albeit mind bending) gameplay.

Zendoku from Zoonami and Eidos looks fun and will definitely give players' gray matters working overtime. The minigames and the puzzles themselves look challenging. The characters are varied from the samurai Musashi, the Kendo master Sakura, the sumo wrestler Yatta, fencer Lorraine, the ninja Kingkage and the others. The trailers also show the training mode with the master. The classic Sudoku game is also in attendance, along with the game's grid game of symbols instead.

There hasn't been any official announcements as to Zendoku's release, but it was said to expect it this year. Might as well check out the screens and trailers while you're waiting. Enjoy!

Some more videos and a whole lot of screens at Full Article!

Zendoku for the PlayStation Portable (PSP) and Nintendo DS (DS), simply put, is a logic-based puzzle game Sudoku with a karate twist. It's not hard at all to understand but what's curious is the idea behind this game. Gaming site Pocket Gamer recently sat down with game developer Martin Hollis to find out once and for all.

Hollis, at the beginning of the interview, jokingly mentioned that Sudoku needs ninjas and that's all the explanation the fans will ever need. And then he commented that it is Zoonami Ltd.'s priority to come up with good and unique video games. He admitted that there were a lot of bumps along the way and the title wasn't really intended for the handhelds. Hollis remarked,

We've made a large number of game prototypes on a variety of platforms and learned a lot along the way, but unfortunately struggled to find development deals that were right for us. With Zendoku, we didn't decide specifically to make a DS or a PSP game. The important thing for us is to make a good game and choose the right platform for it.

And we believe that it has all the potential to become a great game. Instead of numbers, players will be matching up colorful symbols in Zendoku. Aside from the puzzle game, there are various characters available with his own unique graphics, themes and storylines.

"Every time you complete a row, column, or 3x3 box on the sudoku grid, you launch an attack on your opponent. You also launch an attack when you fill in all nine of one symbol," Martin Hollis explains. Speaking of attacks, take note that these can be blocked provided that your character's lucky symbol is quickly placed on the grid.

Aside from the head-to-head combat, there is also a single player mode where everything is the same except the your opponent now is time. Accordingly, placing the lucky symbols on the grid will stop the clock momentarily. Even though Zendoku wasn't originally planned for the handhelds, Martin Hollis believes that it is a match made in heaven,

Zendoku is perfect for DS because it's a vibrant, colourful, fun Nintendo-style game. The sudoku gameplay is perfect for the stylus and the attacks are more fun on the DS with a stylus than without. Equally, we feel PSP definitely needs more fun, casual games that are pick-up-and-play, so we've developed another version of Zendoku especially for it.
