Doodle Fill
App colors your world, but won’t rock it

In Doodle Fill, players are given four colors and blank pages reminiscent of the coloring books we all used as kids. To complete a level, fill in all the empty spaces, but be careful not to fill adjacent spaces with the same color. At first, it’s a no-brainer, but as the patterns get more complex, you may find yourself eyeing the timer as you complete the puzzles.

The game comes with 40 levels that get harder as you go along but nothing that will completely fry your brain. You can also purchase up to 120 levels from within the app. While not a complex game, Doodle Fill is good, addictive fun for those looking to pass some time. If you’re looking for a real challenge, however, you might want to give this one a pass. Free, for iOS.
