Here are definitions for various types of sports bets commonly found in sports betting:

Moneyline Bet:
A moneyline bet is a straightforward wager on which team or player will win a game or event. There are no point spreads involved. Odds are presented as positive or negative numbers, indicating the potential profit or loss relative to a $100 bet.

Over/Under (Totals) Bet:
An over/under bet, also known as a totals bet, involves predicting whether the total combined score of both teams in a game will be over or under a specified number set by the sportsbook. It doesn't matter which team wins; you're betting on the total points scored.

Point Spread Bet:In a point spread bet, the sportsbook assigns a handicap (spread) to the favored team and an advantage to the underdog. You wager on whether the favored team will win by more points than the spread or if the underdog will keep the game close or win outright.

Parlay Bet:
A parlay bet combines multiple individual bets into one larger bet. To win a parlay, all of your chosen bets must be correct. Parlays offer higher potential payouts but are riskier since one wrong pick results in a loss.

Futures Bet:
A futures bet involves wagering on an event or outcome that will occur in the future, often before a season starts. Common examples include betting on a team to win a championship or a player to win an award.

Props (Proposition) Bet:
Proposition bets, or props, are bets on specific events or outcomes within a game or event. These bets can cover a wide range of possibilities, such as the first player to score a goal or the number of three-pointers in a basketball game.

Teaser Bet:
A teaser bet is a type of parlay that allows you to adjust the point spread or totals in your favor for a lower payout. Teasers are common in football and basketball betting.

Round Robin Bet:
A round-robin bet is an advanced form of parlay betting where you select multiple teams and create various parlay combinations within a single bet. It provides a balance between risk and potential reward.

Live Betting (In-Play Betting):
Live betting allows you to place bets on a game or event while it's in progress. Odds are continually updated to reflect the current situation, and you can wager on various outcomes as the game unfolds.

Spread Betting:
Spread betting is a form of wagering where you bet on whether the actual outcome will be higher or lower than the sportsbook's prediction. It's popular in some regions, particularly for predicting point totals.

These are some of the most common types of sports bets you'll encounter in sports betting. Each type offers a different approach to wagering and can cater to various strategies and preferences.
