In Particle Pop, you are playing God in the time right after the big bang. The universe consists of elementary particles such as quarks and electrons, some hadrons such as protons and atoms like hydrogen. Your job is to combine particles to form larger particles - for example combining two up-quarks and a down-quark to form a proton or combining an anti-proton and a positron to make anti-hydrogen. When matter and anti-matter collide, the result is an annihilation resulting in photons giving you energy. When you have a high amount of energy, you might just be able to find special particles!

This game was developed in one day using Python with Pygame.
