What is Coartada?

Coartada (Spanish for “alibi”) is a single-player deduction game: picture the flavor of Clue — a mansion, suspects, alibis that don’t quite add up — turned into a pure logic puzzle, with no dice and no luck. Each case gives you a floor plan, a group of guests and their statements; your job is to cross-reference them until only one arrangement remains.

If you enjoy logic grid puzzles or Einstein’s riddle, this is their playable version: all the information is in view from the first second, pencil notes replace the eraser, and the case file closes with a solved stamp when every alibi fits.

Like every CultivaGames title, each case is 100% solvable by deduction: you will never need to guess. Coartada is in development and coming very soon to Google Play; in the meantime, you can train your logic with Cat Sudoku, our free cat logic puzzle.

What a case looks like

This is not a screenshot: it is the first case of the game, rendered from its real data. Three suspects, four rooms and the clues that solve it.

The investigation underway: first suspect placed

How to play Coartada

  1. 1 Read the alibis

    Each case arrives with the suspects’ statements: where they claim they were, and with whom. All the clues sit on the same screen, no back and forth.

  2. 2 Pencil out cells

    Cross-reference the clues to mark cells as possible or impossible. Two suspects never share a row or column, and furniture blocks the way.

  3. 3 Close the case

    When every suspect fits their single possible cell, all the alibis line up and the case file closes with a SOLVED stamp.

Detective strategies

Three ways of reasoning that crack any case, from the first glance to the solved stamp.

  1. 1 Lock in the certainties first

    Some alibis place a suspect in a specific room. Start there: every pinned suspect blocks their row and column, and that shrinks the whole case.

  2. 2 Chain your eliminations

    Relational alibis (“A was next to B”, “nobody in the same row as C”) don’t say where someone is — but they say where they are NOT. Pencil in every impossible cell: the answer emerges by elimination.

  3. 3 Use the floor plan

    Furniture blocks cells and rooms come in quirky shapes. When a room has only one free cell left, you already know where its occupant was.

Climb the ranks, detective

Cases are organized in five ranks. Each one demands finer deductions: what starts as a quick glance ends up requiring brilliant-mind hypotheses.

  1. 1

    Apprentice

    Straightforward deductions

  2. 2

    Assistant

    A full house, no tricks

  3. 3

    Detective

    You’ll need to connect the dots

  4. 4

    Inspector

    Demands hypotheses

  5. 5

    Legend

    Brilliant minds only

Frequently asked questions

How do you play Coartada?

Each case is a mansion divided into rooms and a group of suspects with their alibis. Cross-reference the clues to rule out cells and place every suspect: two suspects never share a row or column, and furniture blocks cells. When all the alibis fit, the case is solved.

Is it like Clue?

It shares the flavor — a mansion, suspects, alibis — but it is a different game: a single-player logic puzzle with no dice and no luck. It is closer to logic grid puzzles than to the board game: all the information is in view and the case is closed by deduction alone.

Do I ever have to guess?

No. Every case is 100% deducible by logic: there is always a reasonable next step, with no blind trial and error.

How many cases and difficulty tiers are there?

Cases are organized in 5 detective ranks: Apprentice, Assistant, Detective, Inspector and Legend. Each rank raises the bar, from direct deductions to cases that demand brilliant-mind hypotheses.

When does Coartada come out?

Coartada is in development and coming very soon to Google Play for Android. If you want a heads-up on launch day, write to [email protected]. In the meantime you can play Cat Sudoku, our other logic puzzle.
