Merge Dragons! is a free-to-play merge puzzle and camp-building game where you combine magical objects, hatch and evolve dragons, and restore a cursed fantasy world, all at your own pace. Discover a magical world where every object hides a secret and every merge brings you one step closer to saving it. The vale of Dragonia was once a thriving magical realm until the evil Zomblins cast a curse of fog and darkness across the land. Now it's up to you to heal the world by merging everything around you: dragon eggs, ancient trees, fallen stars, mythical creatures, magical flowers, and countless treasures. Merge dragon eggs to hatch loyal companions, evolve them into mighty ancient dragons, and watch them roam your camp harvesting resources while you plan your next move. MERGE DRAGONS! FEATURES: == Merge & Evolve Objects == • Merge 3 identical objects to evolve them into something rarer and more powerful then keep chaining, because the combinations go deeper than you'd expect • Explore 500+ unique objects across 81 challenges: dragon eggs, magical plants, ancient relics, fallen stars, coins, treasures, mythical creatures, and so much more • Merge Life Essence to unleash healing energy and restore Dragonia's cursed lands piece by piece • Find hidden Gaia statues in each level and merge them to solve the puzzle and breathe new life into the world • Discover over 1,600 object combinations. == Collect & Evolve Dragon Breeds == • Meet unique dragon breeds, each with their own look, personality, and special abilities • Evolve every dragon through growth stages, from a tiny hatchling all the way to a legendary ancient dragon • Unlike most merge games, your dragons are active companions: hatch them in your camp and they'll roam freely, automatically harvesting objects for you while you focus on merging • New limited-edition dragon breeds arrive with every bi-weekly themed event, the collection never stops growing == Puzzles & Quests == • Over 180 hand-crafted puzzle levels, each with unique layouts, hidden secrets, and satisfying challenges that test your merge strategy • Nearly 900 quests to keep you busy and rewarded — complete them to earn rare items, dragon eggs, and valuable camp upgrades • Daily quests with Kala keep every session feeling fresh, with new goals and rewards every day • Hidden levels are scattered across Dragonia some players never manage to find them all == Build Your Dragon Camp == • Your camp is your home base in Dragonia: build it up, decorate it, and expand it as you heal more of the land • Earn Dragon Power by merging objects and completing puzzle levels to push back the evil fog consuming your camp • Collect and restore magical structures, buildings, and decorations as you reclaim the land from the Zomblins • The more dragons you hatch and evolve, the more your camp truly comes alive == Play with Friends == • Visit your friends' camps, discover new strategies, and send gifts • Join a Den, the game's guild system to play alongside a community of dragon defenders • Chat in real time, trade tips, and band together to tackle group challenges and earn exclusive Den rewards • Fresh bi-weekly themed events give your whole community something new to explore and collect Download now and discover where Merge Dragons will take you!
