Griductive Game Guide

Welcome, detective.

A new grid lands every midnight Eastern. Every person on it is secretly criminal or innocent, and the only way to tell them apart is the web of clues their cards reveal. Every clue is true, and exactly one set of verdicts fits all of them at once.

Griductive rewards deduction. Only call a verdict the clues already prove — a wrong call costs a chance. Judge a suspect correctly and their card flips to reveal a new statement, cracking the case open one step at a time.

The rules

How to play

Input

Controls

  • Tap a suspect to call them criminal or innocent.
  • Tap a solved card to spotlight its clue — it lifts up and colour-codes the people it names; press & hold it to dismiss a clue you're done with.
  • Mark pencils coloured notes; Hint spotlights the next step.

The setup

Every person on the grid is secretly criminal or innocent, and exactly one arrangement satisfies every clue. A few people start already identified — your foothold into the grid.

Grids grow across the week: a gentle Monday case up through the knottier weekend ones. A new case opens daily at midnight Eastern Time.

Deduction

1. Make a call

Tap an unidentified suspect and choose criminal or innocent. Call it right and the card flips to reveal that person's statement; call it wrong and you lose a life. Only call what the clues actually prove.

A correct call flips the card and hands you a new clue. Green is innocent, red is criminal.

2. Read the statements

Every flipped card carries a statement — your evidence. Tap a solved card to select it: it lifts to the front with a badge, the rest of the board dims, and its words colour-codeexactly who it counts. Colour only shows on the card you've selected, so a hue always means “look here”.

3. Mark & Hint

Mark lets you pencil a coloured note on any suspect without committing — tap a card to cycle its colour: red for a criminal hunch, green for innocent, then three neutral hues for grouping. Stuck? Hint works in steps: first it rings the statement(s) you need, then it points at the very person you can identify next.

Crack the case

Identify everyone correctly and the case is solved. Every grid has exactly one consistent set of verdicts, so any line of reasoning that never contradicts a clue gets you there.

Turn on Relaxed mode (members) to explore without losing lives, and members can peek at the answer any time from this menu.

New each day

One new grid on the desk each day.

A new Griductive grid opens at midnight Eastern Time. Early in the week the deductions are short and friendly; by the weekend you'll be chaining several clues together before the case cracks.

  • Mon & Tue: quick reads
  • Wed & Thu: midweek chains
  • Fri & Sat: tighter logic
  • Sun: the week's deepest grid
