Star Battle Puzzles vs ThinkerLoop

Master the elegant logic of Star Battles. A classic star-placement puzzle sometimes referred to as “Two Not Touch,” Star Battle challenges you to place stars under strict no-touch rules using pure deduction. Star Battle Puzzles is a sophisticated, hand-crafted experience designed for the discerning puzzle enthusiast. No ads, no gimmicks—just pure, uncompromising logic. Love the cat, dog and bunny "doku" puzzles or LinkedIn's Queens? You already know how to play: Star Battle is the original. Our 1-star grids use the same rules, with no ads, ever. When you're ready, step up to 2- and 3-star grids up to 14×14. While others offer only simple grids, we provide a complete range of challenges from approachable to expert. From relaxed introductions to deep, demanding logic, every puzzle is designed to reward careful reasoning. We are the only app to feature the massive 14×14, 3-star grid for the ultimate logic test. Five Distinct Challenges: - 8×8 (1-star) - 10×10 (1- and 2-star) - 12×12 (2-star) - 14×14 (3-star — our signature challenge) Pure Logic, No Guessing: Every puzzle has a single unique solution that can be reached entirely through deduction—never by trial and error. Zen-Focused Design: A minimalist, distraction-free interface keeps your attention on the grid and the logic, nothing else. We believe in a magazine-quality puzzle experience: - No Advertising — no banners, pop-ups, or interruptions - No Locked Levels — all grid sizes and star counts are available immediately - No Gated Features — every tool and mode is accessible from the start Learn as You Play: Intelligent hints explain why a move works, helping you develop deeper logical insight rather than simply revealing answers. Based on the classic Eight Queens variant, the rules are simple: - Place the required number of stars in every row, column, and outlined region - Ensure no two stars touch, not even diagonally - Use logic to eliminate cells and place stars with certainty All puzzles are rigorously tested to ensure they are solvable without guessing.
