City Water System Simulator

The water-system prompt asks for a city dashboard with a reservoir, treatment plants, neighborhoods, pipe flows, and failures. When a pipe bursts or demand spikes, pressure and supply should change across the city.

Prompt

Build a 2D simulation of a city's drinking water system: 1 reservoir, 3 treatment plants, a network of pipes, and 20 neighborhoods with varying demand. A demand producer makes households and businesses use water throughout the day (morning shower peak, midday for businesses), and a distribution consumer balances flow from plants to keep pressure stable everywhere....

Fortytwo Prime

Fortytwo

PASS5 / 5

Fortytwo Prime passes all five City Water System criteria, showing the full reservoir-plant-neighborhood map, pressure and flow visuals, time-based demand, event triggers, and live event feedback.

MiniMax M2.7MiniMax
FAIL0 / 5

MiniMax M2.7 fails all five City Water System criteria because the sample failed to generate, leaving no map, parameter visualization, demand simulation, event triggers, or event response to score.
