How much should you bet? Kelly sizes a bet by how big your edge is. Most pros bet a quarter of it.

Oregon beginner & legal guide
- DraftKings Sportsbook is the only legal online sportsbook in Oregon (through the Oregon Lottery). You must be 21+ and physically in Oregon.
- Tribal casino sportsbooks take bets in person, including college games.
- Pick'em apps (PrizePicks, Underdog, Sleeper) are a legal gray area. Read each app's rules first.
- Offshore sites that take Oregon players are illegal and might not pay you.
- Somewhere else? Rules differ by state and country. Set your region and books in Settings, and only use books that are legal where you live.

Closing line value (CLV)
—After you bet, write down the odds right before kickoff (the "closing line"). If you keep getting better odds than the close, you're betting smart, even during a losing week. Tap "+ Closing odds" on any bet.
Play within your limits
Set a weekly budget before you play. Edge estimates are uncertain, and no bet is risk-free. EdgeBook never suggests more than 2% of your bankroll on one bet.

3 How to read odds
- Minus (-150) is the favorite. You bet $150 to win $100.
- Plus (+130) is the underdog. A $100 bet wins $130.
- If you win, you get your stake back plus the winnings.
4 Kinds of bets
- Moneyline: just pick who wins.
- Spread (Chiefs -3.5): the favorite has to win by more than 3.5. The underdog (+3.5) can lose by 3 and you still win.
- Total / Over-Under (O 44.5): both teams' points added together, over or under the number.
- Player props: bets on one player, like "Kupp over 5.5 catches".
- Parlay: several bets combined, and every leg has to hit. Big payouts, but it's where the books make the most money.
5 How pick'em apps work
- Pick 2 to 6 players and choose More or Less on each stat line.
- On a standard entry every pick has to hit. More picks pay more but hit far less often.
- Use your Start/Sit projections. If a player projects well above his line, "More" might be worth a look.
6 Rules that keep your money alive
- Set a weekly limit in Settings. The Tracker shows how close you are.
- Bet about 1 to 2% of your bankroll per bet. The Bet Finder sizes it for you.
- Never chase losses with bigger bets.
- Track every bet. Your ROI tells you whether you're really winning.
- Log the closing odds. A positive CLV over 50+ bets is the strongest sign you have a real edge.
- If it stops being fun, call or text 1-800-GAMBLER, free and confidential.
