What the lever is
The lever machine sells robot parts. Update 1 added more than 50 new parts and an Early parts setting that chooses which robot tiers the lever rolls. Tier names and the odds change are not published. Favoriting the game is advertised as free parts, with no part names.
A filmed shop state priced Right Arm Bolt Lv1 at 208 Cash. Treat Cash as a confirmed currency for at least that part. Do not assume every lever pull spends Scrap. The panel you open is the price that matters.
Two lever titles
| Action | Count | Title | Buff |
|---|---|---|---|
| Pull the lever | 1,000 | Lever Lord | +9% Luck |
| Buy parts from the lever | 2,500 | Collector | +22% Luck |
Buying one part can be one pull, but the titles are written as different counters. Watch both numbers in Rewards instead of assuming they move together.

Nothing confirms that Black Hole rewards raise Luck.
Spend parts on purpose
Build the six slots you need before you dump duplicates into the Black Hole. A matched set is worth +10% stats from the Perfect trait. A mixed set might still be better, and nobody has published the part stats that would decide it. Ultra Dice is a separate roll from the lever. Dice Master only tells you that 100 rolls is a title, not what the dice pays.
