What's It Like?

The Land of Venn – Geometric Defense is a fast-paced game that teaches kids how to use principles of geometry to defeat an evil wizard named Apeirogon and his monsters. By drawing points, lines, and shapes, kids stop the monsters, called Bookkenriders, from drinking all the Magic Juice found in the Land of Venn. Kids strategically draw shapes to eliminate the Bookkenriders as efficiently as possible. As the game progresses, the Bookkenriders become more challenging, but kids can earn coins to purchase magic spells. There are three wacky worlds to protect, 15 different monsters to battle, 30 levels to complete, and 12 abilities to master, including the Point of Fire, Straight Line of Hope, the Trapezoid of Doom, and much more. Kids are bound to find the game, with its crazy creatures and wonderful soundtrack, seriously addictive.

Is It Good For Learning?

As kids play, they learn about points, lines, and properties of geometric shapes including isosceles, right, and equilateral triangles, quadrilaterals, parallelograms, trapezoids, rectangles, squares, and rhombuses. The game addresses a handful of Common Core math standards, making it a handy curriculum support tool. As the game progresses, it increases in difficulty and encourages kids to use various strategies in order to eliminate the monsters. For example, in the first few levels, kids tap to make a point, which vaporizes a monster, or a Bookkenrider. Then, kids learn that using two points to form a line eliminates several Bookkenriders at once, which is more efficient. Eventually, kids use more advanced shapes and their properties to continue to eliminate monsters and save the Land of Venn. Kids also learn about estimation strategies as they use coins to purchase magic spells that will best help them win the game. Some hints along the way could help kids who struggle to efficiently strategize.
