How to play
A short case file, a handful of clues and one guilty party. Every case has exactly one answer that fits all the clues.
- Read the story and the rule that tells you who the culprit is.
- Use the grid to record what you know: tap a square once for ×, twice for ●. A ● crosses out the rest of its row and column.
- When every suspect has a place and an item, fill in the verdict table and name the culprit.
- Close the case to check your answer.
About mystery mini case
A logic grid puzzle, sometimes called an Einstein puzzle, gives you a few categories, such as people, rooms and objects, and a set of clues. Each item matches exactly one item in every other category, and you deduce the matches by ruling out what the clues forbid.
No outside knowledge is needed. Everything you need is in the clues.
