Quick answer
Start here
Finish one visible shelf or area, recheck the in-game progress display, and move through 25%, 50%, 75% and 100%. The badge milestones are official; this guide does not estimate how many objects equal each percentage.

Use the four enabled Roblox completion badges as checkpoints while the game's exact item weighting and area formula remain unpublished.
Checked July 21, 2026
Step-by-step
Follow these checks in order
- 1
Stabilize the first shelf
Use the First Shelf milestone to confirm that your control and placement loop works before chasing a percentage checkpoint.
- 2
Work toward 25%
Stay with visible incomplete shelves or classroom sections. After each group of placements, recheck the progress display rather than counting objects yourself.
- 3
Repeat at 50% and 75%
At each badge checkpoint, scan for remaining visible object families and use the stuck-item flow when a valid-looking placement fails.
- 4
Finish and confirm 100%
Continue until the live game and official 100% badge reflect completion. If they disagree, avoid estimating the missing count and check current game/update status.
If you're stuck
Reset the current check
Stop repeating the same input. Confirm the device binding, reselect the visible object, look for the live placement cue, and use the linked troubleshooting page if the state still does not change.
Common mistakes
When the first attempt does not work
Turning percentages into guessed counts
No published formula maps objects to completion percentage.
Ignoring a stalled area
A visible incomplete shelf may need a control, selection or placement-cue check before more searching.
Assuming a milestone reward
The badges prove checkpoints, not separate item or currency rewards.
