Tips

  • •In the early game, focus on eating food pellets to build mass before targeting other cells. Stay away from bigger bots.
  • •Use the split mechanic to surprise smaller cells that think they are safe. The launched cell travels fast and far.
  • •Your mass decays over time, so keep eating! Larger cells lose mass faster, creating a natural size limit.
  • •Watch the leaderboard in the top-right. If a bot is close to your size, be cautious. You need to be 15% bigger to eat them.
  • •Splitting makes you vulnerable. Each half is smaller, so a cell that could not eat you before might now eat one of your halves.

Frequently Asked Questions about Cell Eater

What is Cell Eater?
Cell Eater is a free browser-based agar.io-style game where you control a cell in a large arena. Eat food pellets and smaller cells to grow your mass, avoid being eaten by larger cells, and compete against AI bots to become the biggest cell on the leaderboard.
How do I play Cell Eater?
On desktop, move your mouse to steer your cell toward the cursor. Press Space to split your cell and launch half your mass forward to catch smaller cells. On mobile, touch the canvas to set your direction and use the Split button. Eat colored food pellets to grow, and consume cells smaller than you to absorb their mass.
How does the split mechanic work?
Pressing Space splits your cell into two pieces, launching half your mass in the direction of your cursor. This is useful for catching smaller cells that are running away. Split cells can recombine after 10 seconds if they overlap. You can have up to 4 split cells at once.
What are the different bot types?
Cell Eater features 8 AI bots with different strategies: Chasers aggressively hunt smaller cells, Grazers focus on eating food and avoid conflict, Ambushers hide near food clusters and strike when smaller cells approach, and Splitters use the split mechanic to catch prey. Each bot has a unique name and color.
How does mass decay work?
Your cell slowly loses 0.1% of its mass per second. This prevents infinite growth and keeps the game balanced. To maintain your size, you need to keep eating food pellets and smaller cells. The decay rate means larger cells lose mass faster in absolute terms.
Is Cell Eater free to play?
Yes! Cell Eater is completely free to play in your browser on PlayBrain. No downloads, no sign-ups, and no paywalls. Your high score saves automatically to your browser.

About Cell Eater

Cell Eater is an agar.io-inspired browser game where you control a cell in a microscopic world, consuming smaller cells to grow larger while avoiding being eaten by bigger ones. Navigate the petri dish environment by moving your cell toward food particles and smaller organisms. As you grow, previously dangerous cells become your prey and new, larger threats emerge. The game captures the satisfying progression of going from a tiny vulnerable cell to a massive organism that dominates the screen. Strategic movement is essential because larger cells move slower, making it harder to chase small prey and easier for groups of medium cells to corner you. The simple eat-or-be-eaten mechanic creates natural tension at every size level. Compete against AI cells to become the biggest organism on the board and claim the top of the food chain.

How to Play

  1. Move your cell with the mouse or touch controls toward smaller cells.
  2. Consume smaller cells and food particles to grow bigger.
  3. Avoid larger cells that can eat you.
  4. Become the biggest cell on the board to dominate the leaderboard.
