Drop each box when it lines up with the box immediately beneath it. A clean alignment earns a PERFECT and one bonus point, and consecutive PERFECT drops help raise your score. Your 20-second run begins with the first drop, not when you open the page. These are the developer's stated rules; no frame-perfect winning sequence has been independently tested.
Play the game and understand the goal
Play Last Truck Out free in your browser, by dm9494. It is the final shipment of a shift: a pallet needs loading while the warehouse door descends and the driver waits. Published October 14, 2026 at 21:28 UTC and updated October 23 at 23:41 UTC, it is entered in the 20 Second Game Jam 2026 and shares a setting with the developer's Dungeon Fulfillment.
This is a score-chasing stacking game. Keep freight on the pallet rather than the floor, build a taller stack, and pursue the TOP LOADER stamp. The official description names the stamp but does not state an exact score threshold or unlock formula.
Controls and confirmed scoring
| Control or event | What it does |
|---|---|
| Mouse click or Space | Drops the current box |
| First drop | Starts the 20-second clock |
| Box aligned with the one below | PERFECT drop, worth one bonus point |
| Several PERFECT drops in a row | A chain that improves scoring |
| Number keys 1, 2, 3 | Change difficulty |
| R | Restart |
| M | Toggle mute |
A high pile alone is not the same thing as a PERFECT chain. Alignment matters, and a box falling off the pallet is a poor trade for one hurried extra drop.
A practical run, from first box to finish
- Open the official page and select a difficulty if you want to compare settings.
- Observe the box and pallet before your first input. The timer has not started yet.
- Drop the first box with a click or Space and keep it on the pallet.
- For each following box, look at the box directly underneath. Release as their horizontal positions line up to aim for PERFECT.
- When the 20 seconds end, compare the result with your last attempt. Press R and change just one aspect of your timing.
Troubleshooting a low score
| Symptom | What to test next |
|---|---|
| Boxes miss the pallet | Prioritize a safe landing before speed |
| Boxes stack but no PERFECT appears | Reduce sideways offset |
| The chain breaks | Try one slightly earlier or later drop |
| The opening feels rushed | Study the starting position before drop one |
| Scores vary across difficulties | Compare attempts on the same setting |
The developer's page does not provide the collision tolerance, box speed, exact chain formula, or TOP LOADER requirement. Treat the timing suggestions as repeatable experiments, not a guaranteed exploit.
Quick questions
Does the clock start on page load? No. It starts on your first drop.
How many points is PERFECT worth? One bonus point per PERFECT, with additional scoring benefit from chaining. The precise chain calculation is unconfirmed.
How do I unlock TOP LOADER? It is presented as a score goal, but the threshold is not documented in the public description. Build consistent PERFECT streaks and avoid losing boxes.
Is mobile touch supported? The official instructions specify click and Space; touch behavior was not directly tested for this guide.
Bottom line and sources
Prepare before drop one, land on the pallet, and make consecutive aligned drops. The truck is leaving in 20 seconds; somehow the real job is millimeter-level warehouse choreography.
