Click or press Space when the falling box is lined up with the box directly below it. A well-aligned landing earns a PERFECT and one bonus point. Consecutive PERFECT drops raise your score further, so the aim is to build a reliable stack rather than panic-drop freight.

Open the official browser game and select Run game. You are loading the last truck of a shift while the dock closes. The developer says the 20-second timer begins with your first drop, not simply when you open the page.
| Control or event | Confirmed effect |
|---|---|
| Click / Space | Drop a box |
| R | Restart |
| M | Mute |
| Number keys 1, 2, 3 | Change difficulty |
| PERFECT | A box lined up with the one beneath; one bonus point |
| Repeated PERFECT drops | A chain that improves scoring |
A practical run from the first box to the last
- Before dropping anything, identify the pallet and the position of the moving box. Pick one difficulty setting to keep your early attempts comparable.
- Release the first box over the pallet. That first drop starts the clock.
- For every following box, watch the top of your existing stack. Release when the incoming box lines up with the box immediately below.
- If you see PERFECT, aim to repeat the same alignment. The creator confirms chains matter but does not specify an exact multiplier formula.
- If a box lands off-center, re-evaluate the remaining landing area instead of blindly copying the previous timing. Keep the next box off the floor.
- At the end of the 20 seconds, compare your score and restart with R. Once consistent, test keys 1, 2 and 3 to compare difficulties.
| Problem | Useful adjustment |
|---|---|
| Rushing the opening | Look at the pallet before triggering the timer |
| Dropping off-center | Use the current top box as the alignment reference |
| Only one PERFECT | Prioritize repeatable alignment and chains |
| Scores cannot be compared | Keep difficulty constant while testing |
| Boxes hit the floor | Favor a safe landing over a speculative bonus |
TOP LOADER and FAQ
How do I unlock TOP LOADER? It is a stamp named by the developer, but its precise score or stack requirement is not published in the accessible description. Is a PERFECT worth one point? It awards one bonus point; the complete scoring formula is unverified. Does the timer start before the first box? No, the first drop starts it. Which difficulty is easiest? The numeric shortcuts are confirmed; their ranking has not been independently checked. Does a floor drop end the game immediately? Avoiding the floor is a stated objective, but the exact failure trigger has not been tested.

Build a sequence of aligned drops and preserve the chain for a better score. The truck leaves in 20 seconds, yet apparently the warehouse still expects premium stacking standards.
