Navigate a world of courting peacock spiders to create the ultimate spider!

In Spinder, students play the role of a breeder trying to create peacock spiders with specific traits. The peacock spiders vary in three traits: tail size, tail colour, and dance rate. As students navigate the goals for each level, they learn about how selection functions, how the value of a trait changes the relative effect of selection, why selection on multiple traits may be more difficult, and why populations vary in phenotypes.

The intuitive dating interface allows students to quickly grasp concepts and test different ideas of how selection functions.


Spinder is a single player game that is best assigned as homework prior to introducing the concept in class. The game is perfect for a flipped classroom style of teaching.
