World 4 & Update History — +1 Stone Skipping Update Tracker

+1 Stone Skipping updates fast for a game barely a month old: launched September 5, 2026, updated September 30, and now in its World 4 era per the official icon. This tracker is the dated, source-checked version of that history — what shipped, when, and which codes each milestone brought.

Verified update timeline

Date	Milestone	What we can verify
2026-09-05	Launch	Game live on Roblox by Meow Labs (Roblox API creation date)
mid-September 2026	World 3 era	WORLD3 code live (Skill Potion + Common Egg per GameRant, September 26); THANKYOU code live (Win Potion + 4 Wins)
late September 2026	Growth milestones	5KCCU code for the 5,000-concurrent-player milestone (Potions + Wins)
2026-09-30	World 4 update	Last-modified timestamp on the Roblox API; official icon now shows the WORLD 4 banner
early October 2026	World 4 era codes	WORLD4 (Potions + Skill), 10KCCU (Potions + Wins + Skill), SECRET (Potions + Eggs) all active per the October 2 check

The pattern is consistent enough to plan around: a new world means a new WORLD<n> code, and community milestones mean nKCCU celebration codes.

What the World 4 update changed

The September 30 build is verified by its API timestamp and the official icon rebrand; the developer’s patch notes are distributed through their Roblox group and Discord rather than a public changelog. What the surrounding evidence confirms about the World 4 era:

• A new far-region layer — world banners mark major distance-frontier expansions, the same structure our zones and worlds guide describes
• Fresh code waves — WORLD4 and 10KCCU arrived with this era, restocking Potions for the climb
• Live momentum — the game sat at roughly 19,800 concurrent players and 5.2M visits at the October 2 check, with a 96% positive vote ratio on Roblox

Specific World 4 mechanics (new throwables, pets or zone names unique to this world) are not yet publicly documented; this page sticks to what the API, official art and code history can prove.

How to use update days

Update day is the highest-leverage day of the game’s cycle:

1. Redeem the new WORLD<n> code immediately — it expires when the next world lands, the same way WORLD3 died at World 4
2. Rejoin a fresh server — updated servers run current numbers; old instances can lag a version behind
3. Re-check your records — if the update rebalanced distance, your personal bests may be cheaper to beat than yesterday
4. Plan Rebirth around the wave — permanent strength plus fresh codes plus a new frontier is the best climb environment the game offers

What usually comes next

Based on the game’s own four-week rhythm: the next milestone is either a CCU celebration code (the 5K → 10K sequence suggests 15K/25K drops are planned) or the World 5 update. When either lands, this tracker updates with a new dated row and the codes page re-verifies the full list — that re-verification date stamp is the difference between this page and the competitor wikis running September codes in October.
