Somewhere inside the box, lodestones are hiding. You can't see them. You can only fire probes into the machine and watch what comes out. A beam that flies straight through? Nothing in its path. A beam that never comes out? A direct hit. A beam that exits somewhere unexpected? Now you're getting somewhere. Every deflection is a clue! Induction is a pure logic deduction game in the tradition of the classic Black Box puzzle: a hidden grid, a limited set of probes, and everything solvable by reasoning alone. No luck, no timers, no move-matching. If you love Minesweeper, nonograms, or picross-style deduction, this is that same "aha!" — with beams.
