Since 1986 • 40 years of continuous development
The most comprehensive financial simulation ever made. Trade stocks, bonds, options, futures, and more across 1,600 simulated companies. Now remastered for Steam.
What Makes It Different
Not just a trading game. A full economic simulation with real corporate finance mechanics built by a Harvard-trained tax attorney and CPA.
A massive interconnected economy with companies across every sector. Every stock price, every earnings report, every market move is simulated in real-time.
40 years of continuous development by a single creator. More financial instruments and mechanics than any other simulation. Stocks, bonds, options, futures, crypto, ETFs, swaps, and derivatives.
A global following from Antarctica to Zimbabwe. Players have gone on to careers at Goldman Sachs, Morgan Stanley, and hedge funds managing billions.
Be a ruthless robber baron or an ethical investor. The karma system tracks your unethical actions. Anti-trust regulators are watching. Crime doesn't pay — eventually.
PE ratio arbitrage from 1960s conglomerate strategies. Consolidated tax accounting based on actual IRS regulations. Built by someone who structured billion-dollar mergers in real life.
Open-source UI built on web technologies. Full REST API. Write trading bots in Python. The community can mod every aspect of the interface.

What People Say
"An 'imaginative, stimulating' business simulation."— Investors Business Daily (front page article)
"I've been playing your game since I was 13 years old. Couldn't even afford to buy the full version. So I played the two-year version for years and years. And it taught me so much that now I'm working for Morgan Stanley as a forex trader in Shanghai."— Wall Street Raider player
"It's like the Dwarf Fortress or Aurora 4X of the stock market. There really is nothing like it on the market."— Outsider Gaming
"I've seen the source code of the game and I still can't beat it."— Ben Ward, Lead Developer (Steam remaster)
