The Fennels Figure Math is an educational adventure game. The strange, wacky backstory is about Great-Great-Great Grandfather Bezel Fennel, who collected large amounts of strange objects from all over the world and built a large house to store it all in. Now the house has a North Pole Room to store ice sculptures, vines growing wild in the Jungle Room, aliens inhabiting the Backyard Trailer, and a pair of ducks doing one- act plays in the Teepee Lounge.
The game begins when Uncle Bobby (who thinks he was raised by apes) holds a party in the house, inviting many guests such as Albert Einstein and Atilla the Hun (don't ask). Bobby's nephew and niece, Baxter and Frizzie, arrive to discover they were supposed to bring the food. Now they must search all over the house to collect five food items, even though Baxter does most of the work and Frizzie just sits around.
The game has you control Baxter, and while there are a few inventory based puzzles, most involve mathematics of some kind.
