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. You learn as you play. • Works offline — on the subway, on a plane, anywhere. • No account required — play immediately. ■WHO IS THIS FOR? • You love Sudoku and deduction riddles • You want a calm game to give your brain a workout • You want a smart puzzle to share with the family (ages 6+) • You appreciate premium apps with no ads and no subscriptions ■THE LINEALOGIC FAMILY LineaLogic is the sister app of KubiLogic: same standards, same polished design, same promise — no ads, no subscriptions, one lifetime purchase. 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.

Verdict
The clearest difference is in-app purchases: Mental Jigsaw at none against LineaLogic's 1. Mental Jigsaw also leads on iOS requirement (11.0 vs 17.0). LineaLogic's advantage is update cadence (every 8 days vs every 10 months). On price, ads and device support there is nothing between them.
