Nurikabe Vault 4+

Lets start with the good news; the app works, and it works like any puzzler could expect. This is genuine nurikabe, and there's only one solution per puzzle.

Now the middle-ish news. These puzzles are hard. There's no real difficulty curve. For experts, this is a good thing, but beginners should stay away.

Now the bad news. The visuals are a bit TOO fancy. Fancy visuals are for action games; for puzzlers like this, function trumps form any day. This may sound like a silly complaint, but when all you need is a square and a dot, getting creative just feels weird.

THE VERDICT: It's worth the price tag, but better apps exist.

Really excellent overall, much prettier interface than others, good range of difficulties. Would pay for more puzzles. Upgraded graphics resolutions would be nice, but it's held up very well even so. And, a better way to reset levels than un- and then re-installing the game.

Nurikabe Vault is great new brain teaser logic game, in which you use logic to solve puzzles (500 of them are included!). The user interface is a bit quirky but in a fun sort of way using dials to select the puzzle you wish to tackle. Scoring is based on the time it takes you to complete a puzzle and I can tell you that once you start one it's hard to stop. This is a perfect game when you need a the 5 minute break or mental diversion, you could probably solve a handful of the easier puzzles in that time, larger ones might take you longer. I love that there are so many puzzles included, going to take me some time to finish them all haha! The inclusion of Open Feint is pretty neat should you wish to see how your times compare to others or to issue challenges (though I haven't tried that aspect yet).

All in all this game delivers a huge number of fun and engaging puzzles, it's going to see a lot of use on my iPhone.
