Store description excerpt

The classic one-stroke puzzle has dramatically evolved with the simple addition of a numerical rule! Introducing a revolutionary puzzle game for everyone seeking a truly intellectual challenge. This game takes the classic concept of the "Unicursal Trace" (One-Stroke Drawing), a mathematical problem dating back to the 18th century, and integrates the innovative rule of "Numerical Sequence." You're not just finding a path; you're facing a deeply engaging experience that tests both logic and strategic planning. -- Sharpen Your Mind with the New Rules -- The rules are straightforward, but mastery is the ultimate challenge. Prepare to put your brain to the test! [Rule1] Trace all panels in a single, continuous line. You must trace every block (panel) on the board without lifting your finger. [Rule2] As you trace, numbers automatically appear on the panels, indicating the order in which they were touched. Panels already containing numbers must be traced in precise numerical order (1 followed by 2, 2 followed by 3, and so on). This demands highly advanced logical thinking to discover the single, correct path from start to finish. -- Exciting Features That Make It Unique -- - Unique Gimmicks & Mechanics: Puzzle shapes aren't always squares! Face long, rectangular, or hexagonal panels. Beyond numbers, you'll encounter unpredictable gimmicks like "X" and "?" tiles that increase complexity and ensure you'll never get bored. - Pure Logic Experience: No timers, no score attacks. All you need is your concentration and strategic ability. - Massive Content: From gentle levels for beginners to ultimate challenges that will stump even the most seasoned puzzle veterans, we have prepared over 1000 stages for you to conquer. - Daily Brain Training: Use your commute or bedtime to boost your mathematical thinking, improve work efficiency, and keep your mind sharp with stimulating intellectual exercises. -- Infinite possibilities hidden within simple rules. -- Can you become the ultimate puzzle solver, achieving a complete one-stroke trace while adhering to every numerical constraint? Unleash the power of logic and intuition—download the challenge today!
