🏗️ Upper Grand Floating Sky City

You are the planner now. Upper Grand Floating Sky City starts with nothing but power lines and ambition. Tap a ready building to collect its tax, reinvest in bigger blocks, and keep your grid in the black. Keep the meters positive and the tax flowing until you hit the goal — then expand into a tougher layout. It runs on a lean austerity budget: little starting cash and modest yields, so every plot has to earn its keep. Upper Grand Floating Sky City is a free micro city-building game that plays instantly in your browser with one thumb — no download, no sign-up. Unlike a plain idle tycoon, here a resource puzzle sits underneath every tap: a house only pays tax while the power and water it needs are covered, so the fun is in the balancing act. Compact grids, clean vector zones, satisfying collect pops and a steadily rising tax goal make it a moreish "one more block" planner you can dip into any time. With its gentle learning curve, anyone can pick it up in seconds yet still find depth to master. Your progress is quietly saved in your browser between sessions, so it is always ready when you return.

How to play

• Tap an empty plot to place it; the cost is spent and a timer starts.
• Add houses and shops only while your power and water meters stay positive.
• Tap a ready building (🪙) to collect its tax income, then reinvest.
