Two ways to run your book

Every league is yours — your rules, your crew, your season.

House League

The sportsbook experience, fantasy style

Pregame spreads, moneylines, and totals across your favorite sports. The book posts the lines — your crew competes all season with play money. Finish at the top and own the bragging rights.

Bookie League

You set the odds

Think you know better than Vegas? Post your own lines and make offers head-to-head. Talk trash, shade the spread, and let the scoreboard settle who actually knows ball.

Pick'em Coming soon

Straight picks, weekly leaderboard

Pick winners, climb the board, own the week. The classic office pool is on the roadmap — your league will be ready.

From group chat to sportsbook in minutes

No deposits. No real-money wagers. Just sports and bragging rights.

Create your league

Pick House or Bookie, name it something your friends will mock, set the rules.

Invite the crew

Share the invite code. Everyone joins in seconds — phone or browser, same league.

Run the book

Lines move, wagers land, and the standings settle it. Weekend grudge or full season — your call.

Questions, answered

The one everyone asks first: no, it's not real gambling.

Is betbook real gambling?
No. betbook is 100% fantasy. You wager play money for bragging rights — no real money is ever deposited, wagered, or paid out.
What does betbook cost?
Nothing. betbook is free on iOS, Android, and the web.
Which sports does betbook cover?
NFL and college football (NCAAF), NBA, WNBA and men's college basketball (NCAAM), MLB baseball, and NHL hockey. Play a single sport or combine leagues in one competition. Leagues can run a single weekend or a full season.
Can I bet while a game is being played?
No. betbook offers pregame odds, not in-play betting. Place your wagers before the game starts.
How do I get my friends in?
One commissioner creates the league and shares an invite code. Everyone else joins in seconds on iPhone, Android, or the web.
What's the difference between House and Bookie leagues?
In a House league the book sets the lines and your crew bets against them, like a sportsbook. In a Bookie league players post their own odds and make each other offers head-to-head.

Your league. Your lines.
Your season.

The season's already rolling — grab your crew before someone else books the edge.
