Clean the WORLD! Progression & Era Guide

The documented route from your first trash thrower to your first rebirth, built on the official badge data and dated community footage — checked 2026-10-17. Every step names its source; where the game is undocumented, the guide says so instead of guessing.

Quick answer: the whole route

Hire trash throwers and let them feed you cash while collections drop gum. Spend cash on more producers; spend gum in the skill tree on income, chances, and unlocks. The tree walks you through four animal families — horses, unicorns, gorillas, dinosaurs — that map to the four era badges. Each family's droppables (poop, banana peels, eggs) become your income engine, with golden and diamond variants as the jackpot rolls. Bank about 1,000,000 gum to enter the SEA area, then chase your first rebirth (TIME TRAVELER). Sources: badges API (official) and LITTY's gameplay video (2026-08-21) for mechanics.

Step by step

Step 1 · First hours: throwers before everything

Your first hires — the noobs that throw trash — are the cheapest income in the game, and documented runs buy several before touching anything else (a second thrower cost $5 in the referenced video; prices scale fast, so treat exact figures as dated). Cash comes from selling what you collect; gum drops alongside it — "every time I collect a piece of paper, I get bubble gum" is how the recorded run put it. Rats auto-collect and trash cans raise your capacity, so early skill-tree nodes that buff them quietly raise your floor.

Step 2 · The skill tree: where gum goes

The tree mixes three node types: income multipliers (paper value, poop value), chance rolls (double throw, golden-drop odds), and unlocks (rats, horses, unicorns, the thunderstone gun, gorillas, dinosaurs). Recorded play maxes nodes at fixed level caps, and the efficient pattern is to keep producers ahead of multipliers: buy the animal, then the value nodes that make its drops worth selling. Chance nodes compound — a 20% "poop twice" roll stacks with value upgrades on every subsequent drop.

Step 3 · The four animal families (the era climb)

Source: Creators (LITTY, 2026-08-21) — mechanics may have shifted under the 2026-08-25 rebirth and 2026-09-27 PRESTIGE updates. Era names: Official (badges.roblox.com API, universe 10494847029 — award counts checked 2026-10-17 (unchanged from the 2026-10-09 reading); win rates checked 2026-10-03, masked on the 2026-10-09 and 2026-10-17 rechecks).

Step 4 · The SEA wall

After dinosaurs, the game asks for a stockpile: the recorded SEA entry cost was 1,000,000 gum, a whole different area behind a single number. The badge data shows how real that wall is — 46% of joiners reach the dinosaur era but only 27% ever unlock the SEA (Official (badges.roblox.com API, universe 10494847029 — award counts checked 2026-10-17 (unchanged from the 2026-10-09 reading); win rates checked 2026-10-03, masked on the 2026-10-09 and 2026-10-17 rechecks)). Budget it with the cleanup goal calculator: enter your measured gum-per-minute and it converts the remaining stack into sessions. The SEA update guide covers what waits on the other side.

Step 5 · Your first rebirth

The TIME TRAVELER badge — "REBIRTH FOR THE FIRST TIME" — was added on August 25, 2026 alongside the game's rebirth system, and at 32.6% win rate it is the rarest earned award in the game. Simulator convention holds: reset when income growth stalls, in exchange for a permanent multiplier. Two documented changes make rebirthing friendlier now: PRESTIGE removed pay-to-win (all Robux upgrades are free-to-play since September 27), and the badge counts show half a million players have crossed the line before you. What rebirth resets and preserves exactly is undocumented — plan your first rebirth after a stockpile, and note what you personally keep so you can repeat it.

Your checklist

0 of 6 checked

Reference order only — not an official unlock order.

The 27 September official listing no longer names Underground (Chapter 3) as the next update, and Outer Space (Chapter 4) remains coming soon; neither is part of this local checklist.

How far the player base actually gets

Badge award counts double as a progression funnel. Of roughly 3.6M players who joined, about 71% reached the horse era, 64% the mythological creatures, 58% the gorilla era, 46% the dinosaur era, and 27% unlocked the SEA. Only about 14% have rebirthed. The drop-off between dinosaurs and SEA is the single biggest wall in the game — it is where the gum grind bites, because the SEA entry was documented at 1,000,000 gum.

Common mistakes

Questions players ask

What is the fastest way to make money in Clean the WORLD!?

Documented play (LITTY, 2026-08-21) points one way: scale income producers before value upgrades — more throwers and more animals first, then the chance and value nodes that multiply what they drop. Golden drop rolls (golden poop at ~100x) swing early cash more than anything else.

What are the eras in order?

By official badge order: Cenozoic Era (horses), Mythological Creatures (unicorns), Miocene Epoch Era (gorillas), Mesozoic Era (dinosaurs), then the SEA unlock. Badge award counts decline in that same order, which is strong evidence it is the intended route — but the game itself never labels it an official unlock order.

How much gum do I need for the SEA?

Community footage (LITTY, 2026-08-21) showed the SEA area entry at 1,000,000 gum. That number predates the August 25 rebirth and September 27 PRESTIGE updates, so treat it as the best documented figure, not a guaranteed current price.

When should I rebirth?

The TIME TRAVELER badge ('REBIRTH FOR THE FIRST TIME') is the rarest earned award in the game — 504,295 awards, a 32.6% win rate — which tells you most players rebirth late or never. The standard simulator logic applies: rebirth when your income growth stalls, since PRESTIGE made every Robux upgrade free-to-play and removed the pay-to-win reason to delay.

Do I need Robux to progress?

No. Since the September 27, 2026 PRESTIGE update, the official description states all Robux upgrades are obtainable for free-to-play players. Earlier purchases were pay-to-win; that is gone.
