We introduce workshop participants to Quoridor, a multiplayer strategy game for which we've developed an engine in Greenfoot . We use Greenfoot, an interactive Java development environment designed primarily for educational purpose that allows easy development of two-dimensional graphical applications. Participants will first learn how to play the game and then follow a simple algorithm while playing to demonstrate the type of strategies that can be devised in the game engine. The session will then be divided into groups guided by workshop presenters and focus on developing a strategy and implementing it within the Quoridor engine in Greenfoot. At the end of the workshop, groups will be pitted against each other in a Battle Royal.
