About this game

Casewire is a logic-deduction puzzle. Every case is a grid of suspects, locations, times, objects and motives, and a set of clues that constrains them. Mark what cannot be true, mark what must be true, and keep going until only one story is left standing. Then name it.

EVERY CASE IS PROVABLY SOLVABLE

Before a case ever reaches you, it is checked twice. It has exactly one solution, and every single clue is load-bearing: take any one of them away and the case stops being solvable at all. A third check throws out any case that could only be cracked by trial and error. Nothing rests on luck, and you are never asked to guess.

A REAL DIFFICULTY CURVE

More than 60 cases across six chapters, from a 3x3 grid you can read straight off the clues to 5x5 cases where you have to assume something, follow it, and watch it break. Each chapter introduces exactly one new way of thinking. When the chapters run out, the Cold Case Archive keeps generating.

NEVER STUCK, NEVER PUNISHED

• One free nudge on every case, plus a free and unlimited check that tells you how many of your marks contradict the truth — never which ones.
• No lives, no energy, no countdown. A wrong accusation costs you points and nothing else: the grid stays exactly as you left it, and you can try again as often as you like.
• Scratch notes on any suspect, and clues you can strike through once you have used them up.

MADE FOR SITTING WITH IT

• Plays entirely offline. No account, no sign-in, nothing to connect.
• Full English, Spanish, French and German — the clues are composed in each language with its own grammar, not slotted into a template.
• A reduced-motion setting, and grid marks you can tell apart without relying on colour.
• Earn credits by closing cases and spend them on case-file themes, markers, stamps and desks. Detective ranks to climb and a solve streak to keep.

Read the file. Work the grid. Name the culprit.

What’s new

The campaign is now 500 levels across 20 acts, every level verified solvable.

NEW: Story Mode — turn it on in Settings and each case unfolds as a 1930s noir narrative with the clues woven in. Turn it off for the classic clue list.

Every act opens with an animated intro, eight tutorials teach each technique right before you need it, and the Cold Case Archive returns after level 58. Subtitled in EN/ES/FR/DE.
