75HCogTurn

Step into the mechanical world of CogTurn, a purely logic-driven puzzle game where precision and careful planning reign supreme. Unlike fast-paced action games, CogTurn offers a relaxed environment free of time limits, allowing you to focus on the satisfying interlocking of mechanical gears.

Your objective is simple yet deeply engaging: connect all the gears on the screen into a single, cohesive transmission chain. Each gear displays its current phase (a number from 0 to 11). By tapping a gear, you rotate it clockwise by 30 degrees, increasing its phase by 1.

The core mechanical rule:
Two adjacent gears will only mesh when the sum of their phases is an odd number. Once meshed, rotating one gear will drive the other simultaneously, creating a cascading chain reaction! You must foresee how your moves affect the entire system to find the optimal sequence of rotations.

Features:
- Principle Tutorial Mode: Learn the ropes with 30 carefully crafted linear levels. Discover the mechanics of gear pairs, chains, rings, and the unique properties of idler gears that bridge gaps without strict phase constraints.
- Sandbox Challenge Mode: Test your mastery against 50 procedurally generated puzzles. Every layout is unique and guaranteed to have a perfect solution. Can you solve them in the theoretical minimum number of steps to earn a 3-star rating?
- Deeply Logical Gameplay: No random elements after level generation, no reflexes required—just pure strategy and problem-solving.
- Clean Aesthetic: Enjoy a beautiful, distraction-free interface with custom-drawn mechanical gears and smooth animations.

Immerse yourself in CogTurn and experience the unparalleled intellectual pleasure of a perfectly executed full-board rotation!
