+1 Skinny Per Step Worlds

How many worlds the game has, how many players reach each, and what the level gates are.

Neither of these is in the description

The game's store description lists steps, foods, treadmills, rebirths and Auto Wins. It says nothing at all about pets, and nothing about the game having more than one world. Both exist anyway, and we know because the game hands out badges for them, which is the one kind of evidence that cannot be argued with: a badge only exists if a developer made it, and Roblox publishes how many accounts hold each one.

That makes these two systems the clearest example of why this site reads the badge list rather than only the description. A description is marketing copy written once at launch. The badge list is a record of what the game actually asks players to do.

Worlds

Two badges name worlds directly: Reached World 2! is held by 46.1% of players and Reached World 3! by 34.6%. So a third of the players in the badge base have been to the third world, and there is no badge naming a fourth. That absence is weak evidence and nothing more; developers do not always badge every area.

The badge descriptions hint at the theme rather than the mechanics. The World 3 badge text mentions heat, and gameplay footage of later areas is noticeably darker than the bright green starting area. What unlocks each world, and whether progressing costs rebirths or steps, we do not know.

Is there a World 5?

Badges prove World 2 and World 3, and Roblox publishes how many accounts hold each, so those two are measured. There is no badge naming a fourth, fifth or sixth world - and the badges were all created on 16 August 2026, which turns out to matter.

Three separate third-party signals now point past World 3. Two creator videos published in early September name a World 5 in their titles. And a guide site tracking this game's event windows lists a "BIG UPD + W4 AND 5" running 23 to 27 August, then a "WORLD 6 + NEW CONTENT" window from 30 August to 4 September.

Those dates are consistent with the badge evidence rather than contradicting it: if worlds 4 and 5 arrived on 23 August, badges created on 16 August would not cover them, which is exactly what we see. That is a real argument, not a proof - the event dates come from a page that cites no source, and a video title is not a screenshot.

So our count stands at three measured, with a fourth, fifth and sixth reported by others and unconfirmed by us. What settles it in one image is the world select screen.

What gates a world

Footage shows the map broken up by gaps, and each gap is labelled with a level - players read them out loud as they go, naming a level 100 gap and a level 125 gap in the same run. Turn up under-levelled and you do not fit through.

That makes level, not skinny, the thing that opens the map. Skinny feeds the multiplier, the multiplier feeds levels, and levels open gaps. We have not measured the level required for each world.

One uncited guide site names the first three worlds Skinny World, Beach World and Volcano World, and puts Beach World at fourteen rebirths. The game's own badges call them by number - "Reached World 2!", "Reached World 3!" - so either the names are in-game labels the badges do not use, or they are that site's invention. We have not seen either name on screen.

Frequently asked

How many worlds are there?

At least three, proven by badges for reaching World 2 and World 3. There is no badge for a fourth, which is suggestive but not proof.

How many players reach World 3?

34.6% of the badge base, measured from Roblox's badge data on the date shown on the systems page. That base starts 16 August 2026, when the badges were created, not at the game's July launch.

How many worlds are in +1 Skinny Per Step?

At least three, proven by badges for reaching World 2 and World 3. Two creator videos name a World 5, which we have not confirmed. There is no badge for a fourth or fifth world.

How many worlds are in +1 Skinny Per Step?

Three are proven by badges. Third-party sources report a World 4 and 5 added around 23 August 2026 and a World 6 around 30 August, which we have not confirmed. No badge exists for any world past the third.

How do you unlock the next world?

Gaps in the map are labelled with a level and you only fit through once your level is high enough - players read a level 100 gap and a level 125 gap off the screen in the same run. The exact level for each world is not something we have measured.
