Krudoku, developed by HelloApps B.V., is a popular strategy game for iPhone and iPad. Those who are looking for a casual numbers game won’t find that here. Instead, be prepared to strategize!

Concept and Gameplay:

What’s better than sudoku? Scrabble sudoku, that’s what! Well, that’s the closest I can come to easily describing Krudoku. Something must be loved about the game, though, because it has almost 100 positive ratings on the App Store.

It’s not hard to see why the game is so popular once you start playing it, though, because it’s a tough new game to master and something I personally haven’t seen before.

The concept of Krudoku is actually fairly difficult to understand. Like Scrabble and Words With Friends, you’re working with tiles that you need to place on a board. These tiles contain numbers, though, and they vary in color. You and your opponent take turns placing strings of tiles on the board to score points. If you put a tile on a bonus spot, you’ll earn extra points. There are a bunch of different “gotchas” that you have to be mindful of, though, such as the fact that you can only make a move when the first number in your string matches one of your opponent’s numbers.

You might be wondering where the sudoku part of the game comes in. This is where things get very interesting. Like sudoku, you can’t place the same number in a row or column. One would think that such an expansive board wouldn’t make this a big issue, but I was already having trouble on my third move. This, coupled with the rule of different tile colors, makes Krudoku a game that requires the patience of an angel. Therefore, it might not be for everyone, but if you’re willing to take time to learn and develop strategies, it can be a fun game to play.

Krudoku is packed with exciting gameplay concepts, but it also has quite a few features that make it even more exciting. Being able to start an unlimited number of games is definitely a plus, as well as having the ability to choose your opponent from Facebook friends, phone contacts, or searching for them via email or username. Another feature that ties into this is account creation, which gives you the option to play Krudoku on multiple devices if you log in with your credentials.

Lastly, I do want to mention that Krudoku is strictly an online game, meaning you have no choice but to play human opponents. It seems like there are quite a few players available, so finding a multiplayer match shouldn’t be a big issue. However, players who are on non-3G devices like an iPod or an iPad are at a huge disadvantage here, which is why I’d love to see a human vs. computer option. This would not only allow players to hone their strategy without getting frustrated with the game, but also to give travelers something to play while on the road or in the air.


Krudoku can be downloaded from the App Store for free, but it’s supported by ads. If popups aren’t your thing and you’re a social butterfly, there’s a $2.99 in-app purchase that disables ads and unlocks chat. Personally I don’t think the upgrade is mandatory seeing as ads aren’t that invasive and I’m not a huge fan of chatting.
