Pandemic City

PandemicCity is a browser-based city-building strategy game powered by the Kleverchain blockchain. Players build and manage their own city on a 70×70 isometric grid, balancing resources, growing their population, and defending against pandemic outbreaks — all while their in-game economy is backed by real PMD tokens (PMD-2U7V).

Gameplay
Players place buildings, develop infrastructure, and manage six key metrics: budget, population happiness, health, education, safety, and overall city score. Random pandemic events threaten the city with disease outbreaks, requiring players to respond with hospitals, research facilities, and quarantine measures. A dedicated Challenge Mode offers time-limited scenarios with preset starting conditions and competitive scoring, letting players test their skills under pressure.


Marketplace
PandemicCity features a dual marketplace model. The Data Marketplace lets players list their city for sale at a PMD price directly through the smart contract — when purchased, all city data is transferred on-chain and the game state is handed over via the backend, with a 10% transaction fee. The NFT Marketplace allows players to tokenize their city as an NFT and trade it on Klever's native marketplace. Buyers can then claim the city trustlessly through the smart contract by sending the NFT as payment, which burns the token and transfers all on-chain city data to the new owner.

Social Features
A scrollable World Map displays all player cities and NPC settlements on an infinite grid. Players can establish trade connections with each other through a request system, communicate via global, trade, and help chat channels, and compete on a city score leaderboard. A referral system rewards players for inviting others, and daily login rewards plus a milestone achievement system provide ongoing progression incentives.
