"As a public science research organization, the CEA aims to open up the exciting world of science to the next generation of budding young brilliant minds and so made The Quantum Prisoner into a completely free game to lower the entry barrier for a fun learning experience", said Roland Lehoucq, astrophysicist at the CEA and scientific advisor of The Quantum Prisoner. "We've designed the game to be accessible even if you don't know anything about science - you learn as you play along, in line with the scientific approach. Informative videos, facts and assistance from the CEA researchers are all at your disposal as you play through increasingly challenging puzzles and learn about environmental and life sciences, physics, chemistry and maybe even a bit of quantum physics along the way!"
