Today's puzzle felt surprisingly straightforward compared to yesterday. As soon as I saw Landing and Flisht together, a lightbulb went on. The connection seemed almost too obvious to be true. I hesitated after the third clue, but seeing Risers next to Handrail locked it in. The final clue, Floor number (in tall building), fits perfectly into the group, leaving no room for doubt. In the end, the answer Things in a stairwell is one of those 'slap your forehead' moments. It seems so simple once you see the full list.
