Games like Murdle for your next deduction puzzle

For another deduction grid: Deduce

Choose Deduce if the part you want to repeat is crossing out incompatible relationships before deciding who did it, where and with what. Its official site describes daily cases, an archive and detective ranks. You can begin without an account; keeping progress across devices and reaching higher ranks uses an account.

That grid is the important distinction from a card-classification game. You are relating several categories, not only deciding whether each person belongs to one of two groups. If you enjoy keeping several linked deductions in view, this is the closest format match in this short list. If maintaining a grid is the part you dislike, try a clue-reveal game instead.

For a chain of logical next moves: Clues by Sam

Clues by Sam asks you to identify criminals and innocents. Resolving a person can reveal more information. Its rules explicitly reject guesses: a move must follow from the information currently available. The challenge is finding the next justified conclusion, rather than risking an accusation to see whether it was right.

Reading conventions matter. Its definition of neighbours includes diagonals, while a connected group uses orthogonal adjacency. Check those definitions before treating an apparent contradiction as a puzzle error. The official help also explains card tags and a two-stage hint, so you can use those tools when you lose track of which clues still matter.

For suspect cards with a language choice: Detective Grid

Detective Grid starts from an opened card in a grid of 20 suspects. The clues let you prove who is guilty or innocent; opening another card continues the chain. Its language selector includes English, Spanish and Japanese. This can be useful when the logic itself appeals to you but English conditionals make another game harder to follow.

The official rules say everyone tells the truth, including guilty people, and a job is not evidence of innocence. It also blocks choices that cannot yet be proved. Choose this for a card-and-clue routine, not for interrogations, searching a scene or deciding which witness is lying.

When you want information from guesses: Meikyu

Meikyu, our game, changes the source of the evidence. You place residents in five slots and get feedback on correct positions, misplaced pieces and absent pieces. Each floor allows six guesses. Relationships between residents add another layer to what you learn over time. You are not reading a murder case, and we do not claim that every next guess is already provably correct.

A win lets you continue descending that day, within your version’s limits. A loss means returning the next day for a fresh puzzle at the same floor. Players progress at their own depths, so this is not one identical daily answer shared by everyone. The web version reaches floor 19, with two additional descents and three training attempts per local day.

On iPhone, floors 1–19 are free. The Abyss Pass is a one-time purchase for floors 20–100. The iOS app supports offline play and iCloud sync; syncing requires a connection. Try the browser version to decide whether feedback-based deduction is what you want before installing.

Decide what should happen when you get stuck

If you want the game to require proof before accepting your move, Clues by Sam and Detective Grid explicitly offer that rule. If you prefer to maintain a deduction grid and make an accusation after working through the evidence, look at Deduce. If you want to submit a hypothesis and use the response as new evidence, Meikyu is the different branch to try.

Also separate access to another puzzle from replaying a finished one. A daily challenge, an archive, a paid pack and a progression system solve different needs. Use the official links to check the current access rules. The reading and feedback style is a better starting point than assuming every daily puzzle has the same difficulty.
