Power on, open trapdoor! Now you almost got through this level, then wham! — and back you go to the start! On this track you have not only to be fast, but also have to use your brains. Who do you have to push so things keep going? Who can you overtake so that you are the first to roll over the finishing line? And who would it be better to warn? — because otherwise you’ll could set off a chemical reaction.

Your greatest allies in this obstacle course are also your nastiest opponents — the chemical elements. Which ones make you heavier, which ones magnetic and which ones flammable? Use the properties of substances like, mass, density and volume, while skillfully switching between the elements so together, you overcome all obstacles.

Many marbles, five levels and a lot of old acquaintances from the periodic table await you and your smartphones. No previous knowledge of chemistry is necessary, but definitely an advantage!

Elements, ready, set, go!
