Clean the Countries Co-op Guide

Karpath’s Roblox page says you can clean alone or with friends. The universe snapshot agrees: online multiplayer, max 20, no split-screen, VIP servers off. This page is the dedicated co-op guide that the players hub only sketched. If you have never parked a silhouette, do one solo bay first (Getting Started).

Why more people is not automatically faster

FILL COUNTRIES counts parked pieces (FILL quotas). Two avatars grabbing the same Brazil cancel a trip. A 20-player public server is a stampede: giants vanish, crumbs scatter, and FILL 2 hides in someone’s Infinite Inventory. Quiet parties of two or three beat a full house for leaderboard times.

Hop if you spawn into a doomed timer. You do not own the instance. Public servers are a shared supermarket, not your private warehouse. If FILL 25 is already at 3 remaining and nobody is calling names, leave. A fresh pile is cheaper than arguing in chat while the clock dies.

Three roles

Runner. Centre pile. Only S-tier and A-tier countries (countries tier list). Drops at the aisle mouth. Does not place. The runner’s job is uncovering crumbs that sat under the United States, China, Brazil, and Australia — not decorating Europe.

Placer. Lives under continent signs. Reads the prompt. Ireland never goes to the Americas bay. Use continent signs if chat is noisy. A placer who colour-sorts is worse than no placer.

Mop. Clean tool only. Hold-click finished floors. Never peels the USA off the runner. Mop is pass 3 of How to Clean Faster, not a second grabber.

Two players: hybrid runner-placer on Americas+Europe versus Asia+Africa+Oceania. Three players: add mop. Four: second runner. Stop adding floaters. A fifth “helper” who wanders both aisles will steal your FILL 2 into a backpack and forget it.

Callouts that work

Say the country name and continent: “Pakistan, Asia.” Not “the red one.” Not “over here” under supermarket lights.

Timer calls: “0:40, crumbs only.” Bay calls: “Europe full, mopping.”

Voice for the last 20 seconds. Chat for pass 2 names. On mobile, type the continent first if the country name is long. Controller players should not open the Roblox chat menu while holding a giant — drop with LT, then type.

If two people shout the same USA, the second caller becomes mop for ten seconds. Do not wrestle the silhouette.

Spawn, hop, and party size

Invite through Roblox party, then join the same place. Karpath still has no verified Discord (Discord and Trello). Do not paste QR codes from random chatters.

VIP / private servers remain off on the universe snapshot, so you cannot buy a quiet instance. Your options are a small party in a public server, or hop until the lobby is calm. Max 20 is a cap, not a target.

Device mix is fine. One player on PC, one on phone, one on controller can still split aisles if everyone learned the controls table. Mobile camera freeze after equipping the cleaner is why mop should stay on mop — switching tools mid-callout loses the prompt.

Economy in a party

Cash and gamepasses do not pool. Each account opens T / Y for its own carry (Pets and Cash). The mop should buy clean speed. Runners buy carry and range. Robot Vacuum passes help the buyer, not the whole 20-stack (gamepasses).

Do not open Pets for a group screenshot mid-FILL. Do not compare Head Start receipts while FILL 12 is ticking. Spend after the toast, or you will drop the last island in the shop UI.

Etiquette

Do not peel a stranger’s giant. Do not dump pieces off-map. Do not paste executor loaders in chat (scripts). Do not send Discord QR codes. Use Roblox party.

Codes are per account and still none public (codes). A teammate who “has a code” for this place is quoting a different Clean-the-X game until you can redeem it on Karpath’s HUD.

If you peel by accident, drop immediately and say the country name. Silence after a steal is how public servers turn toxic.

Practice ladder

1. Solo FILL 12.
2. Duo aisle split, FILL 25.
3. Trio with mop, stacked FILL 2.
4. Screenshot the toast, then compare notes on How to Clean Faster.

If your team keeps failing FILL 2, you are colour-sorting or mopping too early. Slow the callouts, not the grab. Walk one continent, then the next. The continent signs sheet is the map; this page is the staffing plan.

Official place: Clean the Countries. Group Karpath Games. Last universe publish in this snapshot: 13 September 2026, still 20-player, still online co-op. Visits sit around 772K with about 3.6K playing — vanity, not a reason to jam 20 people into one FILL.
