Reading the signs
-200: risk $200 to profit $100, a 2-in-3 favorite (66.7% implied). +200: risk $100 to profit $200, a 1-in-3 shot. Evens is +100. And -110 both ways on a spread means the implied probabilities sum past 100%, that overage is the vig, the book's margin made visible. In decimal (how the rest of the world reads prices): -200 is 1.50, +100 is 2.00, +200 is 3.00.
Odds floors in the fine print
US welcome offers set their qualifying bars in this notation. '-200 or longer' means -150, +100, +200 all qualify while -300 doesn't. Every structure on our bonus pages states its floor where the book publishes one; this page is how you read it.
The mistake everyone makes
Reading -200 as 'bigger number, bigger payout.' Minus means favorite: the bigger the minus number, the shorter the price and the smaller the payout. It's the single most common misread in American betting, and it matters for offers, because odds floors like -200 or longer exclude heavy favorites.
