About

Induction

Read full description

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. HOW IT PLAYS • Fire probes into the edges of a hidden grid • Read the results: hits, deflections, reflections, pass-throughs • Mark your deductions in the grid until you're certain • Seal your answer. Clean solves and streaks are tracked. WHAT'S INSIDE • Over 1,000 hand-tuned puzzles across notebook collections, from gentle on-ramp to expert codex • A new Daily Challenge every day. The same puzzle for everyone, and streaks to keep • A tutorial that teaches by demonstration, not walls of text • Beautiful vintage-laboratory notebook style PLAYS ANYWHERE • Fully playable offline (commutes, flights, dead zones) • No account required. Sign in with Google or Apple only if you want your progress backed up or synced across devices • Progress backup and cloud sync when signed in FAIR & FOCUSED • Free, supported by ads; rewarded ads are always your choice • No pay-to-win, no energy systems, no consumable nonsense • Your brain is the only power-up From Connexus Digital, the makers of Connexus Puzzles. Charge the coils. Fire the probe. Find what's hiding.
