Moshimo StockSim

Moshimo StockSim is a real-time stock market game where every player trades in the same market.

Start with ¥1,000,000 (about $6,700) in virtual cash, read the news, and buy and sell 200 fictional Japanese and US companies. Prices move every 30 minutes — driven by breaking news, follow-up stories, and the orders of every other player.

Features

• One shared market — your trades and everyone else's push prices up and down.
• News that moves prices — but not always the way you expect. Some good news gets sold off.
• Two trading sessions — the Japanese market runs 8 AM–11 PM JST, the US market 8 AM–11 PM ET, so something is always open.
• Daily, weekly and monthly rankings — top 10 daily finishers earn a star on their profile.
• Real US stock mode — trade real US stock prices with virtual money.
• Friends, chat and custom avatars.
• Also on iOS and Android (same account).

Notes

• Free to play. Optional rewarded ads in the app.
• All companies in the main market are fictional.
• Prices are shown in USD with JPY in brackets (the market itself runs in yen). Red = up, green = down (Japanese convention).
• No real money, no real trading. This is a game, not investment advice.
