World's Biggest Sudoku and Word Search – Big free puzzle games for Windows Phone

Windows Phone has plenty of Sudoku and Word Search games to choose from. But it has never been home to the biggest games of those types – until now. UK-based developer Supersonic-Software and Appy Nation (a consortium of developers who team up to act as publisher) have just brought their popular World's Biggest Sudoku and World's Biggest Word Search games to Windows Phone.

What do the World's Biggest games have going for them? Each one claims to have the largest collection of puzzles of their type (for a mobile game), which means they'll give you plenty to puzzle over at home or on the go. They're free and supported by ads, making for an easy download with no barrier to entry. And both games are really slick, providing a great interface for the puzzlin'. Read on for hands-on video and impressions!

This Sudoku game doesn't give players any fancy novelty game types – just over 350 hand-crafted Sudoku puzzles to choose from. After completing your first puzzle, you'll start unlocking new puzzles on a massive grid, which creates a nice sense of progression. I hate when Sudoku games just throw random puzzles at you with no connective tissue or method of replaying past puzzles.

The interface is simple and intuitive. By default, you just tap a square to fill in the number with a pen. If the number is right, you'll earn some coins to spend on unlocking stuff. If it's wrong, the number turns red but you won't be penalized.

Note taking is a big part of Sudoku, and World's Biggest pulls off that aspect better than most games of this type. Tap the pencil icon found above the number row to switch over, and then you can pencil in tiny numbers as needed. The cool thing is, if you fill in a three within a 9x9 grid and it's correct, all the penciled-in 3s within that grid will disappear. No need to erase them as you'd have to do in some games!

World's Biggest Sudoku offers five visual themes to choose from, ranging from plain black to colorful butterflies. It also has a relaxing background tune, lending to the classy presentation.

World's Biggest Word Search

Word searches are grids filled with letters. Within that grid, players must hunt for words provided from a list. The words can appear in all eight directions, so you'll need a keen eye to spot them all among the alphabetic chaos.

Like World's Biggest Sudoku, this game offers over 350 word search puzzles for adults to take on. Each puzzle has its own theme, and there are over 5,000 words to find in total. That's a lot of word hunting!

World's Biggest Word Search also has a kids mode with a totally separate set of kid-themed puzzles. These are easier and have kid-friendly word themes. Only a few of the kid puzzles are free. You have to pay $2.99 to unlock the rest. Not a bad price if your kid is into word searches.

Unlike World's Biggest Sudoku, this one doesn't offer multiple visual themes. Still, on the whole it's a slick package.

Free to play puzzling

Both games are supported by advertisements. They appear at the top in Sudoku and at the bottom in Word Search. If you don't dig the ads, they can be disabled for 99 cents – always a welcome option.

The two games also have coin and gem systems. Coins can be spent on hints or to automatically complete the optional side missions. Beating side missions gets you rewards and increases your level, adding another progression mechanic to tie things together.

Coins and gems (or a permanent coin doubler) can be bought via IAP, but the hints and cheats you'd spend those on kind of spoil the fun anyway. If you enjoy these games, I suggest at least paying to disable ads. Developers gotta eat!

I'm not much of a word search guy, but I'm really impressed with both of these games. They look great and have excellent interfaces. The multitude of puzzles, challenges, and in-game trophies to seek will keep puzzle fans busy for weeks.

    Finally some brain cracking stuff *-*
  • Im just too idiot to play Sudoku :D
  • How come ? Thats easy .. Once u figured out how to do it
  • That's true. Once you understand the concept the game can be incredibly easy. I'm a Sudoku junky and complete at least one puzzle prefer day, sometimes more if I have the time.
  • Awesome to see another "biggy" in the store :)
  • Speaking of Sudoku, I don't get why Microsoft don't port their own Xbox enabled Sudoku game (available on 8.1/8.1RT) to WP (there's only an old sudoku by Msft studios in the store, which doesn't sync with the tablet one).
  • I like the one on Windows 8.1, I like that I can use my SP3 stylus to write in answers.
  • I don't like that it treats the mouse like a pen also. On desktop if you drag the cursor even one pixel when clicking it switches to pen input, deselects the current number, and inevitably decides you wanted a "1" there. Hairpullingly frustrating when trying to set fast times.
  • I've only ever played it with the pen or dragging the tiles with my finger, so I had no idea.
  • None is available here in Brazil.
  • I love word games. World's Biggest Word Search looks like fun!
  • Excellent games, and I'm really glad one can get rid of the ads for a price - first thing I did!!! Wish msft solitaire could do the same!
  • Off topic - if any of you use it weather flow just got an update
  • You are late
  • Tempting, but it seems like it requires a lot of unnecessary permissions.
  • Did you see the picture? Windows Phone apps has lots of ads in their apps. How sad
  • It's extremely common for free games to have ads on every platform. And as mentioned in the story, users can choose to disable the ads via in-app purchase. Don't troll.
  • I really like that cyan 920
