Taken to a single game, "How to bet over under?" splits into three questions. Three bet types carry most of the action on team sports: the point spread, the moneyline and the over under total. Each asks a different question about the same game. What the spread asks is by how much, the moneyline asks who wins, and the total asks how many points both sides score together. Reading all three makes most of a betting menu clear.
Over under betting, also called a total, ignores the winner and asks about the combined score. The book sets a line, and a bet on the over wins if both sides together score more, the under if they score less. How over under bets work around whole numbers matters: a line of 45 can land exactly, and an over under bet can push, returning the stake. A half point line such as 45.5 removes the push. Totals usually include overtime as well.
Is over under a good bet? It carries the same margin as a spread, so it is neither better nor worse by design. To bet over under well, a bettor needs a view on pace and scoring that the line has not already absorbed, which is rare against a market that sees every public number. The honest summary for all three types is that none beats the margin by itself, and a price is only good when the true chance beats the implied one.
A moneyline is a straight bet on who wins, with no points involved. What a moneyline means is simply the price on each side to win the game. How the moneyline is determined follows the rule of any price: an estimate of each side's chance, plus the margin. Moneyline bets work best where the result is close to even; a heavy favourite pays so little that one upset erases many wins. A moneyline 3 way market adds the draw as the third outcome.
Whether both sides together score more or less than the line the book sets, regardless of which team wins.
A line such as 45 can land exactly, and when the combined score equals it the bet pushes and the stake comes back.
None beats the margin by design; each carries a similar cut, and a price is good only when the true chance exceeds the implied one.
In most sports it does, and the final score after overtime settles the bet unless the market says regular time only.
Only on which side wins the game, with no points added; heavy favourites pay so little that a single upset wipes out many wins.
A line such as 45.5 cannot be hit exactly, so the push disappears and every bet either wins or loses.
