Business games have a long tradition in corporate learning and are experiencing a comeback these days because of their unique capability to provide learning through experience. Based on the extended model of learning through experience by David Kolb, it is possible to integrate online business games into blended learning scenarios in corporate learning using its main advantages such as mastering complexity, the achievement of higher cognitive objectives, learning from mistakes without risk through trial and error, learning from operating experience through time-lapse and particularly strong learner motivation. The German insurance industries are using business simulations to teach learners how to act in environments with complex business and economic inter-relationship networks. Using the example of the closed, stochastic and single player online business game “SiVa – a simulation of an insurance agency” – a concept of a blended learning scenario and its theoretical background are presented.
