Project P.I.T.T. Upgrades
Source-labelled Project P.I.T.T. upgrades, including the current Luck leveling evidence boundary, without invented effects, costs, caps or unlock thresholds.
The registry covers six source-labelled upgrades, including Luck. The official patch record through 1.0.8 does not define Luck's effect, prerequisites, per-level requirements, costs, cap, or relationship to Lucky Products. Those mechanics remain deferred—not guessed.
Can't level up Luck? Here is the verified boundary.
Direct answer: Steam discussions checked on 4 September show players encountering a purchasable Luck progression row, including one report of being stuck between levels 9 and 10. Neither that report nor the official patch record through 1.0.8 explains the requirement. There is no verified unlock condition, progress formula, level cap, or universal fix to publish yet.
What does Luck do?
DEFERRED — EVIDENCE INSUFFICIENT. The official patch notes through 1.0.8 do not define a Luck effect, percentage, probability, multiplier, or relationship to Lucky Products. Community discussion confirms the question exists, not the answer.
How do you level Luck?
DEFERRED — EVIDENCE INSUFFICIENT. One older discussion proposes combos, chain combos, or lucky items only as possibilities and explicitly supplies no numbers. Those hypotheses are not requirements or troubleshooting steps.

A reproducible check, not a guessed fix
- Record the displayed game build and the exact Luck row before the test.
- Change one candidate input only; keep the save, product type, machine layout, and other actions controlled.
- Capture the before/after bar state and any on-screen Luck message.
- Repeat the control and changed run. Treat a one-off movement as a lead, not a rule.
If level 9 does not move, do not assume level 9 is the cap and do not spend around an invented prerequisite. Preserve the observation until a repeatable current-build result or first-party explanation exists.
Panel Rack
Update 1.0.5 added multi-panel carrying, 1.0.6 added a dedicated keybind, and 1.0.7 added interact-key binding plus automatic dispense.
Unlock condition not yet reliably verified.Sticky Tools
The official FAQ says this upgrade lets a panel remain in place when placed in contact with the floor or another stuck object.
Demo V1.0.1 moved it earlier, after panels.Throw
The official FAQ states that right-click throws an object once the Throw upgrade is unlocked.
Unlock condition not yet reliably verified.Time Extension
A older full-release Steam strategy guide names Time Extension as a combo-window upgrade.
Unlock condition not yet reliably verified.Time Stability
A older full-release Steam strategy guide names Time Stability as a combo-window upgrade.
Unlock condition not yet reliably verified.Luck
Steam player discussions show a visible Luck progression row; official patch notes through 1.0.8 do not document its effect or leveling rules.
DEFERRED — EVIDENCE INSUFFICIENT.Current source-qualified effects
Panel Rack is the strongest first-party upgrade record. Time Extension and Time Stability come from an older full-release community guide, not a new current-build replay. Luck is accepted only as a community-reported progression label; its behavior remains unverified. Sticky Tools and Throw retain official FAQ/demo behavior, but their final-release unlock timing is not filled from assumption.
Why there is no tier list
A best-upgrade ranking would need a build, criteria, and release evidence. Rather than create false certainty, the database marks uncertain priority as UNRANKED.
Use progression for next steps
The upgrades page explains documented effects. If the question is what to pursue next, use Upgrade Progression; it is designed as a checklist rather than a database dump.
Update 1.0.8 and CONSUMERISM!
Update 1.0.8 fixes Upgrade Terminal text layout and changes mining upgrades to three ores each. It does not publish a complete unlock tree. CONSUMERISM! officially says to unlock and buy everything, but this source-limited registry is not a complete in-game purchase checklist.
