What the wording tells us
Two things have to line up: you take the last remaining nook, and that is what wins the round for you.
Taking a nook that does not end the round does not satisfy the wording.
What players report
CommunityCommunity guides, not official material.
Both guides describe recesses along a tunnel where only some are usable at a time, with a train coming through the middle.
What the official text does not say
Community accounts do not settle these — they are gaps in the official wording, and we would rather name them than fill them in.
- The official text does not say how many nooks a round has, or what makes one of them the last.
Worth knowing before you try
- Local sessions played before 2026-08-13 may not have registered this achievement — registration in Local mode was broken until v2.1.1.
- Common is derived from the global unlock rate rather than from anyone's judgement of difficulty. How the tiers work →
The simulation
Claim a nook in the tunnels before the others do; taking the last one wins the round.
