All Clues True: Crime Logic

Every published case must pass an automated independent-solver gate for exactly one complete solution and a deduction path that needs no guessing.

The planned opening gives 12 campaign cases without any UMP or Google Mobile Ads call. After that, free play uses the highest UTC calendar day observed locally on that device: each such day allows three new campaign-case unlocks plus its Daily Case. Moving the device clock backwards does not return to an earlier quota day; moving it forwards can advance the locally observed day. An already opened case never relocks.

Structured clues, candidate-specific exclusions, undo and redo, autosave and explanatory hints are designed to preserve the player’s reasoning instead of revealing facts from a hidden answer.

The 120-case launch catalogue spans ten settings and passes automated validation. A case is described as published only after the complete human play-through is also approved.

The planned free version has no banners, app-open, exit or in-board ads. Premium is a restorable one-time purchase, not a subscription, and suppresses every ad request.
