Card-based design toolkits are growing in popularity to support more inclusive and creative design processes. They are also adopted in educational contexts to promote rich and playful learning experiences. Most toolkits are used in co-located workshops where the design process unfolds in the context of the multi-faceted face-to-face interaction among participants. However, recent restrictions have set strong limitations to co-located workshops and forced many to think about digital alternatives. This paper describes DigiTiles, the digital transformation of Tiles, a Card-Based Design Toolkit for augmented objects in the context of the UN Sustainable Development Goals. This transformation is building on an existing commercial shared whiteboard tool and evaluated through 5 design workshops involving 16 participants. The results contribute to increased knowledge about the transformation of card-based design tools from the physical to the digital. The findings from the evaluation suggest that DigiTiles was fun to use and that the prototype supported creativity in digital idea generation workshops. However, some concerns emerged in terms of cooperation within the team. The paper reflects on this experience identifying areas for further research.
