Private leagues for your crew
Your crew.
Your rules.
Your book.
Sidebook is a private sportsbook for you and your friends. Real lines, play money, and one season long race for bragging rights.
No coins to buy. No strangers. No real money on the line.
Built for the group chat, not the casino.
Social sportsbooks want strangers buying coins. Bet trackers want you logging real money. Sidebook is the book your crew runs together, all season long.
Every league is invite only. No public lobbies, no strangers, nobody selling picks. Just the group chat and a leaderboard.
Set the bankroll, the weekly minimum, bonus chips, bet limits and parlay rules. Change them anytime and everyone sees it.
Everyone starts even. The bankroll carries all season, the standings move the second a game ends, and the top spot is earned.
No coins, no sweepstakes, no casino games. Real lines from the big books and your read on them. That's it.
Open a book in two minutes.
Name the league, pick your sports and choose house rules. Casual, Grinder or Sharp gets you started.
Share one link. Everyone joins with the same bankroll.
Lines update all day. Bets settle on their own. The leaderboard does the trash talk for you.
NFL, college, NBA, MLB and NHL. Spreads, totals, moneylines and player props, graded automatically.
Prices flash when they move. If a line changes before you lock it, your slip tells you.
See a pick you like in the feed? One tap puts it in your slip at the current line.
Nobody copies your homework. The whole crew sees what you played once the game starts.
Commissioners can require action every week. Sit on your bankroll and you pay for it.
Add it to your home screen. It opens full screen and works on Sunday when you need it.
Somebody in your group chat is running their mouth.
Put a number next to it. Open a book tonight.
