Secret Laboratory

How to play Secret Laboratory

Secret Laboratory hands you a lab, a rack of empty slots and a notebook that was torn up. The fragments are scattered around the rooms, and each one you reach is a clue about the order of the experiment's steps: this before that, this one first, those two side by side, exactly two steps between these. Set the steps on the rack in the order you believe, then run the batch at the stations. The right order completes the experiment; a wrong one fails the batch.

Every experiment is generated so that its fragments allow exactly one order, so there is always a deduction to make rather than a guess. A containment clock runs the whole time, and a failed batch costs a chunk of it.

There are five experiments. They grow from four steps to eight, bring in more kinds of clue and scatter the fragments further, so the walking and the reasoning both get longer. Three failed batches end the run.

Objective

Rebuild the step order of five experiments from torn notebook fragments and run each one correctly before the containment clock runs out.

Features

• Five experiments to rebuild, from four steps to eight
• Torn notebook fragments scattered through the lab, each a clue about the order of steps
• Several clue kinds: before and after, first and last, side by side, exact gaps
• Every experiment is generated so its clues allow exactly one order
• Set the steps on the rack and run the batch; a wrong order fails it and costs containment time
• Tap, click or arrows to walk and to place steps; three failed batches end the run
