25 new islands: a T-90 tank, a steam locomotive, a space shuttle, the Titanic, an ice fortress and a sunken coral city. Now with music. Sky Cube Builders is a calm idle game about building wonders out of jelly cubes. You start with a bare floating island, one worker and a pile of glowing cubes. The worker picks a cube up, carries it across the island and sets it down — and slowly a house appears. Then a tower. Then a whole landmark. Hire more builders, buy jetpacks so they can fly straight to the top, and watch a crowd of tiny workers turn an empty rock into a city. Thirty-one islands, each bigger than the last: from a first island of 3,500 cubes to a castle on a rock made of more than 200,000. Along the way your crew rebuilds the Eiffel Tower, the Great Pyramid of Giza, the Leaning Tower of Pisa, Saint Basil's Cathedral, the Sydney Opera House, the Taj Mahal, the Colosseum, the canals of Venice, a Santorini cliffside, a smoking volcano, a starship dreadnought, a maze and more — all in cubes. NOTHING APPEARS BY ITSELF Every single cube is carried and placed by a worker. Nothing is spawned, nothing is faked. When you look at a finished tower, someone walked up there with every block of it. WHAT YOU DO • Hire builders and jetpack workers • Upgrade speed, carrying capacity and handling • Tap the island to make the whole crew rush • Move to the next island when the city is done — and come back to any island you have finished ALSO • Watch a short video whenever you like and your crew works twice as fast for three minutes • Brightness, sunlight and colour are yours to adjust • Ten languages • Haptic feedback, with a switch to turn it off • Free, with ads. Nothing to buy, no accounts, no sign-in Come back whenever you like and pick the island up where you left it.

28 new islands — 42 in all. Build a Ferrari Enzo, a T-90 tank in camouflage, a Su-47 jet with forward-swept wings, a hot air balloon, a steam locomotive with its own station, the Titanic and an ice fortress. Each island is bigger than the one before it: the last is close to 400,000 cubes. Day turns to night over the islands, and a comet crosses the dark sky. Photo mode hides the interface so you can capture your island. Every island you finish now records its size and your best time. Background music, off with the same button as the sound. Tap the island and the spot answers — a ripple spreads from your finger and the crew nearby speeds up. More crew speed and depot levels to upgrade. Fixed: the crew could stop working until you reopened the game. Free, with ads. Nothing to buy, no accounts, no sign-in.
