iPhone: 3 awesome puzzle apps!

Aside from the obvious must-have puzzle games, here are 3 random apps that i really enjoy playing.

First off, the obvious ones:

Angry birds, fieldrunners, flight control, tiny wings, cut the rope, zen bound, swap this,... These are definitely worth playing!

Now for the slightly lesser known but still very enjoyable apps:

I Dig It is based on the classic dig for treasure gameplay but has shiny graphics and an in-depth upgrade system. Basically you need to raise cash for a farmer who needs it to pay his mortgage. In the first level you need to raise about 100,000 in 4hrs by digging for jewels and treasure. With this money u can upgrade your digger to be stronger, faster and have more carrying capacity.

The gameplay itself is simple, but becomes more challenging when u go deeper underground, this is a game definitely worth checking out as it kept me busy for days on end!

0.03s is a simple game that relies on your reflexes, not much too say about it other than it keeps challenging u and it always feels great when you nail a level under 0.03s.

Unblock Me free... now this is a great one, the goal is to get the red block to the other side by moving the other blocks. Why is this great? because it challenges you AND has 800 levels... for free! Right now I'm at level 256, if you love brain teasers this is a must-have!
