# Stratum Protocol

> Stratum Protocol (https://sgame.to) is a free, browser-based persistent economic strategy game: one shared world, hundreds of simulated cities across many countries, and an economy driven by real players. Players found corporations, rent or buy land, construct businesses, trade commodities on live exchanges, run logistics fleets, hire staff, and shape city politics. No download, no credit card; every first corporation starts with 100,000 in founders' capital.

Important: Stratum Protocol is an online game. Everything shown here — corporations, parties, markets, prices, people and events — is part of its simulated world and does not depict or represent any real-world company, organization, person, product or trademark. Real place and country names appear only as the game's setting.

Key facts:

- The game world runs faster than real time (admin-tuned multiplier, shown in-game); each country has its own currency, tax regime, and commodity exchange.
- Every city simulates population, labour pool, tax rates, and geographic traits that affect businesses built there.
- All goods are physical: construction materials and shop inventory are bought on exchanges and delivered by player- or NPC-run carriers that burn fuel priced on the same market.
- Playable entirely in the browser at https://sgame.to — sign-up is free at https://sgame.to/sign-up.
