Quick Reference
Understanding Win Probability
Moneyline odds represent the sportsbook's assessment of each outcome's likelihood. Converting odds to probability helps you quickly understand what chance the market gives each side.
For favorites (negative odds like -150), the probability is higher than 50%. For underdogs (positive odds like +150), the probability is lower than 50%. The breakeven point is at +100 or -100, representing 50% probability.
Note: Implied probability includes the sportsbook's vig, so both sides of a market will sum to more than 100%. The "true" probability is slightly lower than the implied probability shown.

Responsible Gambling
Gambling should be entertaining, not a way to make money. Only bet what you can afford to lose, and never chase your losses.
- Betting more than you can afford to lose
- Chasing losses with bigger bets
