Sleuthy: Murder Sudoku Puzzles

Every case has one solution and every step follows from the clues. 56 free cases, two themed packs, no ads, no account.

Sleuthy is a murder mystery logic puzzle. Every case is a floor plan, a cast of suspects and a handful of clues. Place everyone on the board, one person per row and column, and the killer is whoever was left alone with the victim.

No guessing. No luck. Every case has exactly one solution, and every step follows from the clues.

HOW IT WORKS • Read the clues: who sat in the armchair, who could see the staircase, who stood beside the bookcase. • Place each suspect on the floor plan. One person per row, one per column. • When the grid holds, name the killer: the one person alone with the victim.

WHAT'S INSIDE • 56 free cases, from a gentle 4×4 tutorial to 12×12 houses • Two themed packs, Blackwater Hall and The Kestrel Hotel, 40 cases each, one-time purchase • Illustrated rooms, furniture and characters • Pencil marks for your deductions, with undo and redo • Tips that point you to the next person instead of spoiling the case • Every clue explained: tap the info icon to see exactly what "beside" or "could see" means • Wooden pieces, paper and a gavel: sound and haptics that feel like a desk • No ads, no account, works offline
