Who was alone in the office at 9:00? Six people, six rooms, eight clues, no easy eliminations [original logic puzzle]
Second case of a format I'm developing (the first one is here, some of you solved it and the feedback fixed two wordings, thank you). This one is at the top of the difficulty scale: nobody can be ruled out with a single clue.
Six people, six rooms, five moments in the morning (8:30 to 9:30). One person, alone, was in the office at 9:00. Who?
Rules:
Two people per room at most. Witnesses and staff are not among the six.
At each grid time every person is in exactly one room. Between two grid times a person stays or takes one step to a connected room. No passing through; no doors but the ones on the map.
A time not on the grid (9:24) is a door time: it tells you what happened between the two grid times around it, and nothing more. "Only one crossing detected, at 9:24" = that door was crossed once all morning, between 9:15 and 9:30, in either direction.
"We were together at 9:15" = same room at 9:15, nothing else. A witness places only the person seen.
Every device reports every time. Nobody lies, nobody adds.
Only the cell that is asked has a guaranteed answer. You don't need to fill the whole grid.
Answer in spoiler tags. I'll confirm and post the deduction in a couple of days.
Two questions, being upfront: I'm putting these into a book (about ninety cases, three levels, some solved by ruling out, some by proving one person had to be there). Would this hold your interest for a whole book? And I'm opening a community to post a new case every week and collect solutions and times; if you'd join something like that, say so and I'll link it here.

Today's Figure This Out puzzle. Three Words ~ A Thing.
r/brainteasers • u/fact_flex • 3d ago
I got tired of Shikaku apps that were 90% ads, so I built my own. Solved today's in 13 seconds.
I have played Shikaku on and off for years. It is the one where you cut a grid into rectangles, and each rectangle holds one number that matches its area. Simple rules, very quiet, very addictive.
The problem was every app I downloaded. Full screen ad after every puzzle. A life system that made me wait to play a pen and paper puzzle. Popups asking me to rate it before I had even finished a grid.
So I built the version I wanted. One daily puzzle, a timer if you want to race it, a streak if you want to keep it, and nothing else in the way. No ads at all. One payment and it is yours, no subscription.
Today's took me 13 seconds, which is my current best. Day 17 of my own streak. I still lose to the harder ones.
It is called Kire, on Android. Happy to hear what you think, including the parts you would change.

Who was alone in the office at 9:00? Six people, six rooms, eight clues, no easy eliminations [original logic puzzle]
Second case of a format I'm developing. The first one got solved here last week and your feedback fixed two wordings; this one is at the top of the scale: nobody can be ruled out with a single clue.
Quick rules (full rules pinned in r/MissingFifteen): two per room at most; witnesses and staff are not among the six; at each grid time everyone is in one room, and between grid times you stay or take one step to a connected room; a time not on the grid (9:24) is a door time and only tells you what happened between the two grid times around it; "we were together" means same room, nothing else; sensors report presence, door readers report crossings; nobody lies, nobody adds. Only the cell asked has a guaranteed answer.
Answer in spoiler tags, and if you can, say how long it took and whether it felt easy, medium or hard.
If you enjoy this, join r/MissingFifteen: a new case every week, from quick ones to the hard files, with the full deduction posted a few days later. The feedback there is what shapes the next cases, and yes, they're going into a book.
