Quarry

Quarry is a pursuit puzzle dressed as deduction, and its twist is that looking and moving are the same act. A single target hides somewhere on the grid; you tap a cell to probe, and the probe tells you how many king-steps away the quarry is — while simultaneously spooking it one cell directly away from you. That dual nature is everything: you are not reading a static map like minesweeper, you are herding a live thing that flees on a known rule. Probe from the open side and you push it toward a wall; probe near an edge and it has nowhere to retreat, because it never hops off the board. Corners are outright traps. The distance number works like a hot-and-cold reading, but you must always remember it has moved since you took it, so you plan where your probe will shove the quarry, not just what it reveals. Catch it with a probe that lands right on it, inside your budget. Free in the browser, it saves your fewest-probes best to sharpen against.
