About AgarCash

What makes AgarCash different

Most Agar-style games end with a score. AgarCash ends with a balance. The design problem that follows from that is simple to state and hard to build: if a cell is worth money, then every collision is a financial event, and the server has to be the only thing that decides what happened.

So AgarCash is server-authoritative in the strict sense. Your browser sends intent — where you are steering, when you split, when you hold cash out. It never sends outcomes. Movement, collision, consumption, splits, merges, virus effects, disconnects, and cash outs are all resolved by the server, and every financial result is committed through an idempotent ledger transaction.

Mass is not money

This is the rule that shapes AgarCash play. Every cell has two independent numbers:

• Physical mass — sets your radius, speed, collision eligibility, split behaviour and decay. Neutral food grows it.
• Cash value — an integer USD amount you can transfer or cash out. Neutral food cannot grow it.

Food makes you big. Only players make you rich. That is why AgarCash never creates money out of the map: the only way value enters your run is by taking it from someone who bought in.

How money moves in AgarCash

When one player fully consumes another, three things happen at once: the killer takes the victim's physical mass, 10% of the victim’s cash value goes to platform revenue, and the remainder is added to the killer's cash value. Nothing is created or destroyed outside that explicit fee.

Cash value belongs to the run, not to any single cell. You can control up to 16 cells, and your run ends only when the last one is gone. To bank the value you hold the cash out control for 7 seconds — your cells freeze and blink visibly to everyone nearby, so cashing out is a decision with a cost, not a free exit.

If you disconnect, your cells stay idle and vulnerable for 60 seconds. You can reconnect and resume in that window; after it, whatever survived cashes out automatically.

The ledger behind AgarCash

Balances are held in an internal USD ledger denominated in six-decimal minor units. USDC on Solana is the deposit and withdrawal rail, not the accounting unit — which means AgarCash can add assets later without the game logic ever performing price arithmetic.

Deposits credit your balance only after idempotent on-chain verification. Withdrawals separate approval from broadcast, every attempt is idempotent, and larger requests route to manual review. You deposit once, play many runs, and withdraw when you want to.

Fairness and bots

AgarCash practice rooms may run an ambient population of zero-value bots so the free world never feels empty. Those bots use the same authoritative input, physics and cash out paths as a human, and they structurally cannot hold or create cash value. Paid AgarCash worlds reject ambient bot configuration outright.

Teaming and feeding are permitted in AgarCash — they are real strategies in this genre and pretending otherwise would just push them into private channels.

Rooms

AgarCash runs a free Practice world plus continuous $1, $5 and $10 cash rooms. Worlds run non-stop — you join and cash out whenever you like rather than waiting for a match to start. New to it? Read the full AgarCash guide first, then spend a few runs in Practice.
