About Mass Plus

Mass Plus is a physics-driven game where you use self-replicating projectiles to destroy target spheres and complete levels. You can finish levels quickly, but earning high scores takes a more measured approach.

Grow your projectiles

Projectile spheres spawn smaller spheres and consume them, growing until they reach critical mass. As they grow, their pull on nearby spheres increases. You must weigh the benefits of growing a sphere against the risk of it being annihilated, while also deciding whether to finish a level quickly for a lower score.

Score and precision

Your score depends on precision, planning and luck. You can race through levels or aim for a place on the global leaderboard.
