Cell Rush FAQ
Quick answers about playing, accounts, progression and the arena.
Is Cell Rush free?
Yes. The game is free to play in a modern browser.
Do I need an account?
No. Guest play starts immediately. A Shring account is useful for persistent progression, Google or email sign-in, account recovery and owned skins.
How do split cells recombine?
Each split piece has a cooldown. When that expires, move your pieces together. They can overlap and will merge into a larger cell.
Can I feed the green viruses?
Yes. Eject mass into a virus with W. The seven visible indicators fill as it charges; a fully fed virus launches in the direction of the final feed. Viruses are still dangerous at the 16-cell cap because they trigger a mass-losing overload.
How do public and private lobbies work?
Quick Play fills the busiest open public lobby for the selected mode before opening another room. The lobby browser can join a specific public code. Private rooms use a shareable code and can either fill unused slots with bots or remain player-only.
What is Battle Royale?
Battle Royale is a fast elimination match filled to 20 competitors with players and bots. The safe zone shrinks, eliminated players can spectate, and friends joining the room code after the match starts enter spectator mode until it finishes. The complete countdown and round stay under five minutes.
What happens in Rift Control?
Rift Control is a four-minute scored event match. Every player and bot starts at equal mass on a separate spawn slot, and event mode has no viruses. The active control zone rotates around the map; uncontested holders score fastest, contested players receive smaller participation points, pulse orbs add bonus points, and eliminations lead to quick respawns. Strict mass limits prevent anyone from becoming an unstoppable giant.
How does Rush work?
Hold Shift on desktop or the Rush button on mobile for an 18% speed increase. Rush consumes 0.35% of current mass per second and turns off when your mass becomes too low.
Are skins pay-to-win?
No. Skins are cosmetic and do not alter speed, mass, eating range or any other gameplay value.
What browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari are recommended. Hardware acceleration should remain enabled for the smoothest canvas rendering.
