Wobble... wobble... dare to add one more? Balance the Statue of Liberty, then a pyramid, then the Eiffel Tower right on top — stack the wonders of the world sky-high in this one-handed physics puzzle. That heart-stopping wobble right before it all comes down? Instantly addictive. ■ Nail-biting head-to-head battles Take turns stacking; the first to topple loses. Your opponent's strength adapts automatically, so every match is a photo finish — beginner or pro. Perfect for a quick round on the go. ■ Weekly leaderboard vs. real players Compete with the world on a leaderboard that resets every week — the last-minute scramble is the best part. Finish high to earn coin rewards, and chase the all-time board too. ■ Stack your way to space The higher you build, the more the world shifts from ground to sky to outer space — cheered on by an adorable, expressive Earth. A screenshot-worthy view you raised with your own hands. ■ Collect them all — the Heritage Book Every landmark you stack is added to your collection with its flag and a surprising, share-worthy trivia fact. Level up to unlock new wonders, one after another. ■ Easy to learn, hard to master Just drag and release. You'll get it in seconds — but stacking them just right? That's the addictive part. ■ Daily login bonuses The more days you play, the more coins you earn. Spend them to unlock your favorite landmarks early. How high can you go before it all comes tumbling down? Raise your own tower of world wonders. * This app features real-world structures but is not affiliated with, endorsed by, or connected to UNESCO or any of its organizations.
