Real gameplay, straight from the game

Accretion is a real-time game of cosmic growth. You start as a mote of dust and grow by absorbing everything smaller than you. Dodge anything bigger, or it shatters you and costs a life. Each time you evolve you pick a new skill, so every run plays differently. It starts easy and turns brutal: a fast climb from dust to a living world, and a place on the leaderboard.

Your run is tied to your account, not your browser. Clear your history or switch devices, sign in with the same email, and your world is right where you left it.

Climb the leaderboard

Every run is scored against the whole field, and your best run holds your rank. Start a new world and your climb resets, so the board stays a real fight.
