Alibi Daily Logic Grid

The desk lamp is low, the corkboard is pinned with index cards, and one line-up of the night is true. Alibi is a daily logic-grid deduction puzzle set in a 1920s detective bureau — the classic zebra / Einstein-style elimination puzzle, dealt fresh every night. Every case pins four suspects, four rooms, four weapons and four times of the evening. Exactly one arrangement lines them all up, and a full sheet of clues sits beside a cross-reference grid of - and x cells. Read a clue, mark the grid: tap a cell to cycle blank → - → x, and every - auto-crosses the rest of its row and column, just like working a paper grid with a pencil. Cross out what the clues forbid, and the lone survivor in each row and column is the truth. When the whole board is pinned, close the case and name the culprit. The clue set is always complete and self-consistent, so straightforward elimination always reaches the one answer — there is never a guess, and never a puzzle without a solution. Right the first time is a clean solve; every wrong mark is counted against you. • One deterministic case at midnight, the same board for everyone in the world • A true logic grid: clues on the left, a -/x cross-reference grid on the right • Auto-crossing rows and columns do the pencil-work, so you can think • Name the culprit — the suspect matching the coroner's time of death • Streaks, a clean-solve rate, and a spoiler-free share card • Practice bench with unlimited fresh cases once the daily is closed • Entirely offline and private — nothing collected, ever Four suspects. One is lying. Work the board.
