Back to your next call.

On Play, choose a 5- or 15-minute window and tap Bitcoin, Ethereum, Solana or XRP. Enter a practice amount and tap Buy Up if you think the price will finish at or above the price to beat, or Buy Down if you think it will finish below. Each share pays $1 if its side wins and nothing if it loses. Total payout if correct includes your stake.

No. 15-Minute Markets uses practice money only. There are no deposits, wallets, withdrawals, real trades, prizes or in-app purchases, and practice funds cannot be bought or redeemed. Prices, order books and results come from public market data; nothing is ever bought or sold on your behalf. The app is not affiliated with Polymarket.

When you sell all of your shares in a round, the call is finished right away, so it moves from Running to Settled on the Calls tab with a Cashed out label. If you sell only some shares, the call stays under Running until the round settles. See all calls also has a Cashed out filter.

Prices in short rounds can move quickly. When you confirm an order, the app reads the order book again and fills against it at that moment, so the price you get can differ from the preview you saw a few seconds earlier.

Tap Limit on the ticket and choose a price. The order reserves your practice cash or shares and fills when the market reaches your price. Open the app to keep orders matching; iOS may pause matching while the app is in the background. Unfilled orders are cancelled and refunded when the round closes.

A round closes at the end of its window and settles on the official result, usually within a few minutes. Until then it shows as resolving. The round is decided on a 60-second average price at close compared with the opening price; Up wins on a tie.

15-Minute Markets needs an internet connection for live data. Check your connection, then tap the refresh button on Play. Settings › Data feeds shows the status of each feed. If the provider is briefly unavailable, rounds reappear once it is back.

Open Settings with the gear button. Practice cash lets you set any balance and keep your stats, or reset your stats and start over with that amount. Adding practice cash never counts as profit.

On Calls, tap See all calls, then the share button to export your records as CSV or JSON through the iOS share sheet. Exports include every retained call, whatever filter is selected.

Joining is optional. Tap Join leaderboard to see exactly what becomes public, then join under a generated alias; no email, password or real name is needed. Players appear in the standings after ten finished rounds and stay listed by finishing at least one round every 14 days. Tap How ranking works in the app for scoring details. There are no prizes.

On the Leaderboard, tap the player, then the ••• menu, and choose Report name or Block player. Blocking hides that player on your device; to undo it, open the Leaderboard ••• menu and choose Unblock. You can also report a player through our contact form; include their alias and what happened.

Open the Leaderboard ••• menu. Turn off Share my calls to hide your individual calls; your alias and totals stay public. To remove your profile, choose Delete my profile, then Delete profile & stop sharing. Your practice cash and history stay on your device. Keep the app installed until the deletion is confirmed. If you can no longer use the app, send a privacy request instead.

Round alerts are optional reminders to check a round about a minute after it closes while you hold shares. Turn them on or off in Settings › Trading › Round alerts. They need notification permission, which you can change in iOS Settings.

Include your device model, your iOS version, the coin and round length, what you expected to happen, and what happened instead. Never send passwords, payment details or authentication codes.
