🏗️ Upper Greater River Delta City

An empty lot, a blank grid and a vision — Upper Greater River Delta City is waiting for its first block. Place a utility, watch the ⚡ and 💧 meters, then add homes only while you have surplus to keep them earning. On a tiny grid, space is precious, so squeeze the most income from every plot to reach the target. It runs on a lean austerity budget: little starting cash and modest yields, so every plot has to earn its keep. Upper Greater River Delta 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. Short, moreish sessions and a clear goal make it dangerously easy to play just one more round. Everything runs right on the page with no sign-up, so you can jump straight back in any time.

How to play

• Select a building from the shop bar — start with a ⚡ power plant and 💧 water tower.
• 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.
• Grow your tax income to the goal without letting a meter go negative.

Controls
