Sudoku meets whodunit

About Poodoku

Poodoku is a cozy logic-puzzle whodunit for the whole family. Someone pooped in the house, and you have a small cast of suspects, a floor plan, and a handful of clues. Place each suspect in the right room, then use the final empty square to reveal the culprit.

The puzzles combine sudoku-style one-per-row, one-per-column rules with clues such as who was beside an object or sharing a room. Three new puzzles arrive every day in Easy, Medium, and Hard difficulties, backed by a 365-day archive and optional Hard+ five-room grids. An interactive tutorial, X marks, drag-and-drop controls, hints, streak tracking, and an optional reminder make the deduction approachable without removing the challenge.

Poodoku is designed for children and adults to solve together, with gentle stakes, storybook art, large tap targets, light and dark modes, and an optional Cats Pack. It works offline, requires no account, has no ads, urgency timers, lives, or subscriptions, and limits purchases to optional one-time extras.

Why it's here: Poodoku gives familiar grid logic a memorable personality. Its playful mystery, clear deduction rules, and respectful family-friendly design make a daily puzzle feel inviting without making it trivial.
