Clueworthy: Logic Grid Puzzles

A new case every day, the same for everyone. Read the clues, mark the grid and find who did what. One answer each, reached by logic alone, never a guess.

Clueworthy is a book of logic grid puzzles that never runs out, and every one has exactly one answer. A built-in solver checks each puzzle using only steps a person can make, so you never have to guess.

Each puzzle is a short story and a handful of clues. Mark the grid with checks and crosses until you know who ordered the latte, which dog went first, and who took the last slice of cake.

THE DAILY CASE • A new puzzle every day, the same for everyone, always free • Small early in the week, a big 5 × 6 on Sunday • Keep your streak going; a streak freeze covers a missed day

HINTS THAT TEACH • A hint tells you which clue to use and what it proves: "Clue 4 tells us the latte wasn't ordered at 9:00" • Tap again and it fills the marks in for you • Show Mistakes when something doesn't add up

MADE FOR CAREFUL SOLVERS • Five sizes, from a quick 3 × 4 to a 5 × 6 Master grid • Eight settings: a café, summer trips, a wedding, a garden club, a dog show, a book club, an office mystery, a bake sale • Automatic crosses after every check, undo, drag to cross out, an answer table that fills itself in • Adjustable clue text size, Dynamic Type, VoiceOver, light and dark • iPad shows the whole grid and all the clues side by side • Print a puzzle or save it as a PDF and solve it with a pencil
