With regard to an Edu context I would use this game in my minecraft class. I would ask if some students would like to test it, I would give them a time parameter. As I know the kids and they like to have mini competitions I would include that as a motivator, not focused on winning against themselves but beating my score. My focus would be on them explaining to me the strategy that they used to work out the recipes for the elements and if they saw any similarities to how they played that and played their first game of minecraft. I would also be asking them to evaluate the game. In doing that I would be looking at how they communicate and how they interact, how they build knowledge and understanding.
Can be used across a range of platforms as is web-based and comes as an app.
Purpose – could be used in science or as a way of getting students just to think about combinations.
