In this work-in-progress we present a computer-based method to design German reinforcement exercises for children with dyslexia. From dif- ferent schools, we collected more than 1,000 errors written by children with dyslexia. Then, we created a classification of dyslexic errors in German and annotated the errors with different language specific features, such as phonetic and visual features. For the creation of the exercises we took into account the linguistic knowledge extracted from the analyses and designed more than 2,500 word exercises in German that have been integrated in a game available for iOS. The game and the resource of dyslexic errors are available online (https://itunes. apple.com/us/app/dyseggxia/id534986729?mt=8) and they are, to the best of our knowledge, the first contributions of this kind for German.
