LineaLogic vs Induction

A real logic game. Not another app stuffed with ads. Not a subscription that costs you more every month. Just an elegant puzzle where every challenge is solved by reasoning. That's LineaLogic. ■ THE CONCEPT Every puzzle gives you a clue. Your job: pick the right sticks — each one has a color and a size — to satisfy every constraint at the same time. The twist? Constraints overlap. A large red stick counts as both "1 large" AND "1 red". Read carefully, reason it out, choose right. Easy to learn. Demanding to master. ■ WHAT YOU GET → 7 progressive difficulty levels, 70+ deduction puzzles. → Level 1 is completely free — try before you buy. → Zero ads. Ever. Anywhere. → Zero subscriptions. One single lifetime purchase unlocks everything. → No timer, no lives, no game over. Take your time to think. ■ WHY LINEALOGIC IS DIFFERENT Most logic games drown you in ads or charge you every month. LineaLogic respects your time and your money: • Clean, premium design — crisp typography, bold colors, zero distractions. Pure thinking. • A unique mechanic — reading clues and overlapping constraints, not a simple "count the objects". • Clear feedback — a wrong answer tells you why, and you fix it.

If you loved one, you'll love the other. ■ THE MATH IS SIMPLE Dozens of puzzles, hours of thinking, a single payment. Compare that to any $9.99/month subscription. Download LineaLogic. Start with the free level. And when you're hooked, unlock everything. Your brain deserves better than an ad every 30 seconds.

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.
