Kind of like Where's Waldo, except it is Bible based and you look for a variety of different items in the big, busy picture.
For example, part of a paragraph in the section on Gideon goes like this:
"Quiet as two mice (picture of mice to search for), Gideon and his servant (picture of servant) counted out the Midianite camp. They overheard a man (picture of man) talking about his strange dream. 'I dreamed that a cake of barley bread (picture of bread) fell into a Midian tent (picture of tent) and destroyed it."
