Mowing a lawn isn't the most mentally taxing of summer activities, but Lawnmower Challenge will help keep your brain sharp during those lazy afternoons. Lunar Enigma's $2 puzzle game certainly won't dazzle you with its graphics, but its tricky series of obstacles will test your grey matter. To mow the lawn, you'll need to chop down trees, find keys to unlock gates, plant seeds (to grow grass), and even light torches on dark paths. Lawnmower Challenge's 48 levels will keep you busy until fall.
