AppyNation's latest iOS game is Dr. Quizington, a trivia and adventure game in which you'll attempt to find the source of the River Nile.
Yeah, good luck with that - you do realise that top scientists spent years trying to complete that task. The apparent source of the Nile is still up for debate, too.
But, hey, at least you get to travel around Africa in the 19th century with a band of kooky companions.
You'll also need to answer thousands of multiple choice trivia questions to succeed in your many quests, piecing together an ancient map, too.
If you think you've got enough knowledge and know-how to help Dr. Quizington, download the game for free on the App Store.
Oh, and send me a postcard, won't you?
