Can you complete the chain and master the logic? Link Master - Clue Chain is a unique puzzle game that challenges your brain in the most satisfying way. Your mission is simple to understand, but deeply clever: connect two objects using real-world logic and a sequence of associations. Start with one image. End with another. To bridge the gap, you'll need to insert three phrases and two middle icons that make perfect logical sense. Every puzzle follows a fixed seven-part structure: Start Icon → Phrase → Icon → Phrase → Icon → Phrase → End Icon Each phrase must describe a natural connection between the icons before and after it. These can be based on: Relationships: A teacher uses a chalkboard Behaviors: A cat chases a mouse Functions: A sun gives light The key is clarity and logic — no abstract metaphors or wild guesses. If your sentence wouldn’t make sense in the real world, it doesn’t belong in the chain. Game Features Original Puzzle Format Forget traditional match games. Link Master is a fresh, creative format built entirely around logic, association, and intuitive thinking. Hundreds of Handcrafted Levels Each level is designed with care and complexity. Early puzzles are quick and rewarding. Later challenges will truly test your reasoning skills. Diverse Topics From animals and food to technology and people, you’ll explore a wide variety of themes and categories. Clever and Satisfying Every correct connection gives a clear “aha!” moment. It’s logic, not guesswork. Progressive Difficulty Start with easy associations. Move up to longer chains, trickier concepts, and multi-layered reasoning. Casual Yet Smart No time limits, no pressure. Play at your own pace — but prepare to think hard. Great for All Ages Whether you're a student learning about cause and effect or an adult who enjoys brain teasers, Link Master will stretch your thinking in a fun, intuitive way. What Makes It Different? Link Master isn't just another word game. It’s a logic game at its core — one that respects the player's intelligence and rewards real understanding of how things relate in the real world. Each puzzle is like a little riddle made of objects and clues. There are no random connections. Every step of the chain must make real, everyday sense. You’re not just solving puzzles — you’re connecting how the world works. Example Puzzle Level Name: Sun to Rabbit Chain: Sun → gives → Light → needed by → Plant → eaten by → Rabbit Each step can be read forward or backward and still feel natural — that’s the essence of a perfect chain. If you enjoy logic games, word puzzles, or brain challenges, Link Master offers a refreshing and smart new way to play. With simple visuals, challenging ideas, and endlessly satisfying solutions, it's the perfect game to sharpen your mind and have fun doing it. Think you can master the clues?
