Billionaire MAX

Aim to become a billionaire. Online investment battles for up to 4 players.

Billionaire MAX is an online competitive stock investment board game for up to 4 players. Trade shares of 21 fictional companies, navigate world-shaking events, and build your fortune at top speed.

Now, your investment judgment will be put to the test.

A strategy game where you read prices and the market

Choose from 3 investment categories — corporate stocks, venture stocks, and commodities (gold, crude oil, real estate) — and reshape your portfolio while responding to over 50 types of event cards. Buy and sell timing, diversification across 6 sectors versus concentration, long-term holds versus short-term trades — every move decides victory or defeat.

Online play: random matches up to 3 players, password matches up to 4 players

With Steam random matchmaking, jump into instant battles with up to 3 players from around the world. Password-protected private matches support up to 4 players — perfect for gathering with friends and playing at your own pace.

Players holding the same stocks find their fates intertwined. When one player runs away with the lead, everyone else silently bands together to take them down. No one says "let's team up." And yet, the board itself draws the lines between allies and enemies. A different drama unfolds every time.

Strategic elements that decide victory

The objective: collect trophies faster than anyone else. Trophies are bought with cash, and the player who reaches the required threshold wins. But the moment you turn cash into a trophy, it stops growing. "Just a little more profit first" — that one delayed move can be fatal. Only those willing to abandon profits can stand at the top.

• Special Dividends: Hold a certain number of shares in specific large corporations to earn extra dividends on top of regular payouts.
  
• Venture Investment: No dividends, but unlimited price upside. Trade bankruptcy risk for explosive returns.
  
• Short Selling: Read the fall in stock prices and profit from market collapse. A contrarian investor's trump card that can flip the entire game in one move.
  
• Bonus Trophies: Meet one of three special conditions — Conglomerate, Venture Capital, or Commodity — to claim an extra trophy on a first-come, first-served basis. A path to dramatic comebacks.

Over 50 events that shake the world economy

Great Depression, Oil Crisis, Pandemic, AI Boom, New NISA, World War III — over 50 event cards inspired by real economic history and current affairs move the market every turn. Read the wave correctly and you profit big; read it wrong and you go bankrupt. The fight is never over until the very last move.

Only those who never give up become billionaires

Even if you fall behind early, even if your assets are halved mid-game, the chance for a comeback exists until the moment the game ends. Bonus trophies, event-driven short sells, all-in major shareholder strategies — the cards to flip the game are always in your hand. Defeat starts the moment you give up.

Serious CPU battles

Features 4 difficulty levels of CPU opponents (EASY / NORMAL / HARD / EXTREME). EXTREME requires genuine strategy to defeat, delivering a complete game experience even in solo play. Whether you're warming up for online matches or honing your strategy alone, the CPU mode delivers.
