Nurikabe Light
It's not your typical numbersinboxes challenge, but don't let that scare you away. Once you wrap your mind around the concept of using the empty boxes as the clues for filling in the black squares, you're on your way. This first batch of Nurikabe Light features a number of simpler, smaller puzzles to help you learn the ropes. Give them a shot, you might discover a new puzzle addiction!

Nurikabe Tips and Tricks
Getting Started:

Look for numbered squares that are very close to one another. If only one square separates two numbered squares, black out the square between them, since leaving it empty would connect the two numbers. If two numbered squares are diagonally adjacent, black out the two squares they both border.

Look for 1s. Since they are going to be on an island that's only as large as the square they're in, you can immediately black out the four squares surrounding them.
General Tips:

Take advantage of large numbers, particularly when they're near the edge of the puzzle or surrounded by other numbers. If the path of a large number is limited in one direction, you can assume the island must continue in the other direction.

If there's a large open space in the grid, look for larger numbers that can reach that area. Since you can't have any 2x2 clusters of black squares, you can visualize which islands are necessary to fill in that area.

Pay attention to places where a path (either black or white) must continue. Since the black squares must all be connected, a string of black squares that have only one possible outlet must continue through that outlet. The same is true for white squares, except you must remember that the islands will have a limited size and might not continue through those outlets.

Watch for numbers in corners (both in the natural corner of the puzzle and corners made by black boxes). A 2 in a corner must connect one space either horizontally or vertically. In either case, the square diagonal to the 2 must be black (as the rule requiring a border on islands would force a black square there in both situations). Similarly, if you have a longer chain started that has only one square remaining, and it must branch off in one of two neighboring directions, you can black out the square between the two options.

Don't forget about good old trialanderror! If you get stuck, try marking a square as empty or filled and see where the puzzle goes from there. If you have an unresolved 2 available, try starting your experiment there, as you can usually solve that island by proving one direction wrong.

Thanks for explaining the rules more clearly than the game does :)
I have a love/hate relationship with all these Conceptis puzzles. The puzzles themselves are great, but the interface they use is terrible. Every time you beat a level, it shouldn't take you four or five clicks (each followed by a slow animated transition) to get to the next puzzle.
Good package here. As I said before on Hashi lite, the small grid size means that the puzzles never reach the more interesting levels of difficulty, but otherwise solid execution here. I especially like the way chains of black or white squares get highlighted so you can easily spot where they need to go through gaps  on another site with these puzzles I spend most of my time doing the same thing by eye, and it takes much longer.
