🏗️ Upper Compact Neon Megacity

Welcome, mayor. Upper Compact Neon Megacity needs power, water and homes — in the right order. 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 Compact Neon Megacity 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. It works beautifully offline once loaded, turning idle moments into a tiny pocket of fun. Built mobile-first and feather-light, it loads in a blink and stays smooth even on older phones.

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.
