Free Board Games for Kids: Online Strategy Game - With 50 boards to choose from, ALLOUT is a tough game indeed, and it will most certainly put those brain cells to the test.

The first 4 levels of ALLOUT are classified as "Easy" to get you into the swing of things, from that point on you are on your own.
