A case file, not an empty grid
People, places and the investigative question give the puzzle a concrete context. Clues describe the night and are translated into the logic grid.

Indizoku combines Sudoku-like row and column logic with an investigation. People, places, motives and clues create a new crime case for each seed, with exactly one verified solution.

03
What was delivered
A browser-based logic game with 5×5 to 8×8 cases, four difficulty levels, three case types and a verified unique solution.
The challenge
A generated case must be neither contradictory nor ambiguous. At the same time, it needs to feel like an investigation rather than a number grid with a story attached afterwards.
Our product decision
Case generation and solution verification were deliberately separated. An independent solver proves a single solution and reduces the clues to a minimal core set before the case is played.
Available today
Indizoku repeatedly creates new cases across four difficulty levels and several case types, playable solo, with account progress, cooperatively or as a two-player duel.

Reasoning with a system
Row and column rules connect with special case conditions. Notes and progress help players track possible and excluded assignments consistently.
A verified resolution
