GWTTKB Live: every NFL game, your fantasy matchups and your parlaysEvery NFL game on one screen, updated every 15 seconds while games are on: the score and clock, where the ball is on the field, the drive under way, the last play, and each team's chance to win from the live Kalshi and Polymarket markets (the books' pregame price before kickoff).What it tracks

Scores: every game, with filters for live games, the red zone, close games late, your players and finals. Tap a game for every drive and play, the win chance through the game and the box score.

Field: every offense on one field, all driving the same way, so you can see which games are closest to scoring.

Fantasy: your Sleeper, ESPN and Yahoo matchups live, with each starter's points and a real chance to win from 5,000 simulated finishes priced off the player prop markets. Leagues you connected in the Coach show up on their own.

Parlays: add a parlay from a screenshot of the slip (read on your phone; the image is never uploaded), pasted slip text, or leg by leg, then watch each leg settle from the box score and the chance it hits move through the game.

Alerts: touchdowns, field goals, turnovers and finals; touchdowns by your players; parlay legs landing. Swipe one away or tap it to jump there.

Every expected number on it is a market price, labeled as such. Free, no account. Research only, not betting advice. 21+.Week 8 games
