Logic Deduction Puzzles Online, Disguised as an HR Access Review

If you like the reasoning in Sudoku but want words instead of numbers, the logic grid is your puzzle. Corporate Spy is one, wearing an HR access review.

How a logic grid works

There is a leak in the company and you have to deduce who from the clues. Each suspect has a unique department, floor and badge — no two share any of them. Fill the grid with the dropdowns, then press Reconcile to check your logic before naming anyone.

That Reconcile step is what makes it playable rather than frustrating: you find out your reasoning broke down before you commit to an accusation, not after.

Three case sizes

Easy, Medium and Hard change how many suspects and attributes you are juggling. The leaderboards rank fastest cases, each difficulty separately.

Why an access review is the right cover

An access review is a grid of people cross-referenced against departments, floors and badges. There is no gap at all between what the puzzle needs and what the document would contain. Tabs: Directory, AccessLog, Incidents, Notes — file HR_Access_Review.xlsx.
