How to play AgarCash
AgarCash is a live Agar-style multiplayer arena that runs in your browser. You start as a single cell, eat food and smaller players to grow, and cash out before someone bigger eats you. Practice is free; in the $1, $5 and $10 rooms the value your cell carries is real USDC on Solana.
Quick read before you enter a cash room
Practice is for learning. Cash rooms add real value, so read the risk notes below before you play. Every rule that applies to money is listed here — nothing about value settlement is hidden behind the game client.
The nine rules that decide a run
Learn the basics
Move toward your cursor or touch target. Eat food to gain mass, and consume smaller cells to take their value. Split to launch part of your mass forward; eject food to give up mass or feed a green virus.
Example: Learn the basics A win makes you visible
After eating another player, move away from crowded lanes and check the edge of your screen. A bigger cell can still catch you while you are recovering or split into several pieces.
Example: A win makes you visible Cash out from a safe spot
When you are ready, find open space and hold Cash Out for 7 seconds. Your cell freezes during the countdown. If danger approaches, cancel first, then move away before trying again.
Example: Cash out from a safe spot Green viruses split big cells
A large cell that consumes a green virus bursts into smaller cells. You can eject food into a green virus to make it fire another virus, but this can be just as dangerous to you as it is to nearby players.
Example: Green viruses split big cells Red viruses are lethal
Red viruses continuously produce food, but they consume any cell that touches them. The cell's cash value is lost and cannot be recovered. Keep a wide distance.
Example: Red viruses are lethal Paid rooms use real USDC value
In paid rooms, a cell's carried value is real. If another player eats your cell, its value is settled immediately: the winner receives the remainder after the platform fee. Losing your last cell ends the run.
Example: Paid rooms use real USDC value Splits must keep value in every cell
In paid rooms, mass and carried value are divided between the new cells. A cell cannot split if either resulting cell would hold less than $0.01. Tiny rounding differences stay with the cells so the total value is preserved.
Example: Splits must keep value in every cell Low-value cells can shatter
If a green virus would split a cell but its value cannot be divided while keeping at least $0.01 per piece, that cell shatters into food and its carried value is lost. Your other cells remain, but losing the last one ends the run.
Example: Low-value cells can shatter Keep cash and mass in balance
In paid rooms, a large cell with too little carried value decays faster. Keep collecting value as you grow instead of holding a huge, underfunded cell for too long.
Example: Keep cash and mass in balance
