News moves the market

Analyze with charts & data

FAQ
- Q. Is it free to play?
- Yes, completely free. No install required — you can start right in your browser (no in-app purchases either).
- Q. Is a stock game actually good practice for real investing?
- Yes. You go through the same loop as real trading — read the news, pick a stock, place a market or limit order, and review your profit and loss — as many times as you like with ¥1,000,000 in virtual funds. Each stock page also shows charts and metrics like P/E, P/B, and ROE, so you pick up the fundamentals of investing while playing.
- Q. How is it different from other stock games and simulators?
- The biggest difference is that every player shares one single market. Unlike stock games you play alone, prices move with other players' trades and AI-generated news, so you get the push and pull of a real market. Play in your browser or on iOS and Android.
- Q. Is this a real brokerage?
- No. Moshimo StockSim is a simulation game. No real money or personal financial information is ever exchanged, so you can play with peace of mind.
- Q. Does it use real stock prices?
- The core 200 tickers are all fictional. Our "Real Stock Mode" additionally features real U.S. companies' stock prices and news (trades still use only virtual funds within Moshimo StockSim — no real transactions occur).
- Q. Can I compete with other players?
- Yes! All players share the same market. Compete on profit rate and total assets in the global leaderboard.
- Q. Is there a mobile app?
- Yes, available on both iOS and Android. But you don't need to install anything — every feature works right in your browser too.
