🏗️ North Twin River Delta City

Zone by zone, North Twin River Delta City grows from a quiet plot into a humming little metropolis. Every home and business needs power and water to pay tax, so balance your utilities against your growth. Grow income without browning out the city, bank the goal, and chase a higher score. It models a frontier economy: blocks cost more and take longer, but each one pays out richly for patient planners. North Twin 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. With its gentle learning curve, anyone can pick it up in seconds yet still find depth to master. Sound effects with a one-tap mute mean it is just as happy played silently in a waiting room.

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
