Getting started

Pick a scenario and difficulty, and you get 60 trading days of pre-event charts, ₩10,000,000 in cash, and 100 shares of each of 4 stocks. Each trading day you have 60 seconds to read the chart and news, then buy, sell, or wait. When the last day opens, we reveal your return along with the real event, stocks, and dates.

They play the same scenario over different lengths: Easy is 10 trading days (up to 10 minutes), Normal is 20 (up to 20 minutes), and Hard is 60 (up to 60 minutes). Easy and Normal use fixed windows where the event unfolds, so everyone competes on the same days.

Once you start, you can't pause. Even if you close the page or switch devices, each trading day's 60 seconds keep running on server time. When you return, the game has moved on to wherever the clock got to. When you're ready, press "Next day" to move on early.

Instantly, at the closing price of the day you're looking at. You trade in whole shares and pay a 0.25% fee on every buy and sell. You can't trade on the last day; remaining shares are valued at that day's close.

The baseline is your starting total: starting cash plus the day-0 value of the shares you were given. Your final assets (cash plus holdings at the last day's close) are compared against it.

A new scenario opens every day at 00:00 Korea time. You can replay past scenarios for practice at any time.

If a signed-in player finishes their first game of today's scenario before 00:00 the next day (Korea time), it enters that difficulty's ranking. Higher returns rank higher; ties go to whoever finished first. All three difficulties share the same event, so you get one first game per scenario regardless of difficulty; later games only go to your own record.

Prices keep the real chart shape and daily moves, but the price level is rescaled so the stock is hard to recognize. News items are rewritten from what market participants could have known that day. The content is adapted for the game, so don't use it as a basis for real investment decisions.
