Buy a call ▲ or a put ▼, pick your strike, and watch a real stock price run to expiry. Beat the premium and you profit. Play money, no sign-up.
Real Bybit spot prices: daily closes of 10 xStocks (tokens that track US shares), US trading days from July 8, 2025 to September 25, 2026 (fetched September 28, 2026). Each option expires 12 real trading days after the last close on the chart.
This options trading game turns the single most important idea in options, payoff at expiry: into one fast decision per round. You buy either a call (a bet the stock rises) or a put (a bet it falls), choose your strike price, and pay a premium. The real stock price then runs forward 12 trading days to expiration, and your profit is the option's payoff minus what you paid.
The underlying prices are real market prices: daily closes of ten large US stocks from Bybit xStocks, so no round is rigged. The premium is a Black-Scholes estimate from the stock's real volatility over the 35 daily moves on the chart, not a quoted option price, and buying the option and the payoff at expiry each pay a 0.1% fee. Your edge comes from reading the chart's direction and picking a strike that the stock can realistically clear.
Visualise the payoff: a long call's profit grows dollar-for-dollar once the stock climbs above strike + premium; a long put profits below strike − premium. Below those break-evens, the most you can lose is the premium you paid.
Notice the flat sections: an out-of-the-money option simply expires worthless and you lose only the premium. That capped, known downside is exactly why options are a defined-risk way to express a view, and why this drill rewards patience over reckless bets.
Remember: real options carry real, sometimes total, loss of premium and require a brokerage approval level. This is a free educational game, not financial advice; see the SEC's options basics at investor.gov.
New to the mechanics? Skim the trading glossary for strike, premium and expiry, then warm up your direction calls in the up/down prediction game before risking premium here.
A call profits when the stock rises above your strike; a put profits when the stock falls below it. In this game you buy one, pay a premium, and the real stock price 12 trading days later settles your payoff.
No. The underlying prices are real daily closes of Bybit xStocks (tokens that track US shares, July 2025 to September 2026) and the premium is a Black-Scholes estimate from their real volatility, but the premium and payoff are play money, and your running P/L saves only in your browser. Nothing here is financial advice.
The premium is what you pay to own the option. To profit, the option's payoff at expiry must be larger than the premium you paid, exactly like real options. Here the premium is estimated with the Black-Scholes formula from the stock's real volatility on the chart, because no quoted option prices are used.
Each round your payoff minus premium is added to a running bank. Your best bank and win rate are tracked across sessions so you can practice reading direction and strike selection.
