For those slightly more mature than “Angry Bird” addicts, “Slice It!” offers a challenge for players while still providing childish animation. The object of “Slice It!” is simply to cut a shape into a specific number of pieces using as few lines as possible. It sounds simple but becomes quite difficult after passing the first few levels. “Slice It!” is a free app available for download on the iPad, iPhone, and Android and will keep you up way past bed time as you play until the wee hours of the night.
