Frequently Asked Questions
What's the difference between spread and moneyline?
Spread betting requires a team to win by a certain margin, while moneyline is simply picking the winner. Spreads offer closer to even odds, while moneylines reflect the true probability of winning.
How do I convert spread to moneyline?
The conversion isn't exact because spread probability differs from win probability. A team favored by -5.5 points might be a -200 moneyline favorite, implying different probabilities for each market.
When should I bet spread vs moneyline?
Bet moneyline when you believe a team will win but might not cover the spread. Bet spread when you think a favorite will dominate or an underdog will keep it close.
What is implied probability?
Implied probability is the win percentage suggested by the odds. For -200 moneyline, the implied probability is 66.7% (200/(200+100)).
