THE DOCKET

Robots arrive at your repair shop over time. They appear in the docket on the right.

Select a robot to pull it into the repair bay. Press TAB to send your current robot back and swap for a different one.

Robots with a multiplier (x) pay more — but their value decays over time. Prioritise them!

MATH CARDS

Cards in your hand show an operation type and difficulty. Drag a card onto a matching broken part to attempt a repair.

Answer the math problem correctly to fix the part. Three wrong answers and the card is discarded.

Using a harder card on an easy part earns an over-qualification bonus!

MULTIPLIERS AND DECAY

Most robots arrive with a payout multiplier — x1.5, x2.0, etc. This decays from the moment they enter the docket.

The decay bar shows how much multiplier remains. Full bar means full payout. Empty bar means x1.0 — no bonus.

Repair high-multiplier robots first. Every second counts.
