About

🏡 Build your dream mansion on the surface, then hit DIG DEEPER to unlock a secret world beneath it 🚗 Show off your spinning supercar in the hidden basement garage, and chill in the sunken pit lounge and bar 🌊 Swim in your own underground lagoon, relax in the cave spa, and punch the bag in the rock gym 💰 Open the giant vault door to your gold vault, hypercar gallery and private nightclub 🦈 Ride the glass elevator down to the aquarium, the glowing crystal mine, the T-rex fossil vault and the molten lava core 🏰 Pick your style: Modern, Royal Palace, Gothic Manor or Sci-Fi Lair. Visit your friends' mansions too! 🔍 Build it tile by tile (don't fall through!) and unlock every room hidden underground
