About
There’s been a murder at the manor! In fact, more than one!
At a wild party at Saltwood Manor, someone has been killed in every room. Your job, as the investigating detective, is to work out who the killers are.
Whodoku is a calm logic puzzle with a manor-house mystery wrapped around it. There are no ads, no lives and no timer. Take as long as you like.
To solve the mystery, follow three simple rules:
1. Killers work alone
2. Killers stand alone
3. Killers stand apart
Mark the innocents with an X. Double-tap someone to accuse them. When the last killer is correctly unmasked, the case is closed.
Why you’ll like it:
- Fresh cases whenever you want one, each with a single solution
- Board sizes from a brisk 5×5 to a tricky 10×10
- A house full of painted suspects and coloured rooms
- Moody music, weather, and the odd dramatic sting — all optional
- Automatic Xs if you want a helping hand, or mark the board yourself
- Free to play. No accounts. No tracking. Just you, the manor, and a quiet night’s deduction
- Media player to control the soundtrack
