Help Quantum Kate to discover subatomic particles and become a true Quantum Rascal! From Kate's room, you can access the portal to the quantum world and start the game. Coloured particles called quarks will pop up into your room. Connect two or three quarks together by drawing strings between them with your phone and form new particles - but be careful not to cross the strings! The more particles you discover, the more quarks you unlock. Watch out for the quantum particles you created: they are unstable and will decay into more quarks. Find all the particles you discovered in the highscore poster back in Kate's room. Play to beat your best score and discover all the subatomic particles to become a true Quantum Rascal!
