Chances are if you’re hungry, your patience isn’t what it is supposed to be either. Which is why hungry policemen should only be given the Donut Puzzle to solve as a punishment when they scew up on duty. We jest – surely we ought to give our esteemed lawkeepers a chance? This 400-piece jigsaw looks like a donut, but it won’t do much to attract ants unless you literally sprinkle sugar all over it. If donuts are not your thing, there are always coffee, pizza and Chinese food versions available, for £8 a pop from this July onwards.
