How it works

fStock is a chip-based direction game on Flap. Connect your BSC wallet to play — chips are stored on your profile (1000 to start). Call up or down for 30 seconds; win 1.9× your stake if price moves your way.

Chips

Crypto tab — always on

24/7 live Binance spot prices, 1-minute chart, chip rounds anytime. Use this when you want to play now.

Stocks tab — view-only until US market opens

Market closed: browse tickers, 5-minute chart, frozen last bid — no Up/Down, no stakes
Market open: live bid polling and chip rounds unlock automatically

Quotes stop polling while closed so prices do not fake-move between stale API snapshots. The app checks session status every 60 seconds.

How a round works

Pick a ticker and stake (10–250 chips; you start with 1000).
Tap Up or Down — entry price locks immediately.
After 30 seconds, exit price is taken from the live feed.
Win if exit is strictly above entry (Up) or below entry (Down). Flat = loss.
Win pays stake × 1.9 (net +90% of stake).

Wallet & leaderboard

Connect a BSC wallet from the header before playing. Your chip balance is stored on your profile (1000 starting chips). Switch networks if prompted. Solo rounds spend chips only — no BNB required.
