Types of bets

Aside from simple wagers—betting a friend that one's favorite baseball team will win its division, for instance, or buying a football "square" for the Super Bowl--sports betting is commonly done through a bookmaker. Legal sports bookmakers exist throughout the world (perhaps most notably in Las Vegas). In areas where sports betting is illegal, bettors usually make their sports wagers with illicit bookmakers (known colloquially as "bookies") and on the Internet, where thousands of online bookmakers accept wagers on sporting events around the world.

• Proposition bets. These are wagers made on a very specific outcome of a match. Examples include guessing the number of goals each team scores in a soccer match, betting whether a wide receiver in a football game will net more or less than a set amount of total yardage, or wagering that a baseball player on one team will accumulate more hits than another player on the opposing team.
• Parlays. A parlay involves multiple bets (usually up to 12) and rewards successful bettors with a large payout. For example, a bettor could include four different wagers in a four-team parlay, whereby he is wagering that all four bets will win. If any of the four bets fails to cover, the bettor loses the parlay, but if all four bets win, the bettor receives a substantially higher payout (usually 10-1 in the case of a four-teamer) than if he made the four wagers separately.
• Progressive parlays. A progressive parlay involves multiple bets (usually up to 12) and rewards successful bettors with a large payout, but not as large as normal parlays. However in a progressive parley, unlike a regular parley, some of the bets can lose, and a reduced payout will still be made.
• Teasers. A teaser allows the bettor to combine his bets on two or more different games. The bettor can adjust the point spreads for the two games, but realizes a lower return on the bets in the event of a win.
• Run line, puck line or goal line bets. These are wagers offered as alternatives to straight-up/moneyline prices in baseball, hockey or soccer, respectively. These bets feature a fixed point spread that (usually) offers a higher payout for the favorite and a lower payout for the underdog (both in comparison to the moneyline). For example, the above-described Brewers/Cubs baseball game might offer a run line of Milwaukee -1.5 (+100) and Chicago +1.5 (-120). A bettor taking Milwaukee on the run line can avoid risking $200 to win $100 on the moneyline, but will collect only if the Brewers win by 2 runs or more. Similarly, a run line wager on the Cubs will pay if Chicago loses by no more than a run, but it requires the bettor to risk $120 to win $100. Bettors may also wager on so-called alternate run, puck, or goal lines, which offer decreased payouts on the favorite and increased payouts on the underdog.Oneca again using the Brewers/Cubs baseball game as an example, a sportsbook might offer an alternate run line of Milwaukee +1.5 (-300) and Chicago +1.5 (+270).
• Future wagers. While all sports wagers are by definition on future events, bets listed as "futures" generally have a long-term horizon measured in weeks or months; for example, a bet that a certain NFL team will win the Super Bowl for the upcoming season. Such a bet must be made before the season starts in September, and winning bets will not pay off until the conclusion of the Super Bowl in January or February (although many of the losing bets will be clear well before then and can be closed out by the book). Odds for such a bet generally are expressed in a ratio of units paid to unit wagered. The team wagered upon might be 50-1 to win the Super Bowl, which means that the bet will pay 50 times the amount wagered if the team does so.
• Head-to-Head. In these bets, bettor predicts competitors results against each other and not on the overall result of the event. One example are Formula One races, where you bet on two or three drivers and their placement among the others. Sometimes you can also bet a “tie”, in which one or both drivers either have the same time, drop out, or get disqualified.
• Totalizators. In totalizators (sometimes called flexible-rate bets) the odds are changing in real-time according to the share of total exchange each of the possible outcomes have received taking into account the return rate of the bookmaker offering the bet. For example: If the bookmakers return percentage is 90%, 90% of the amount placed on the winning result will be given back to bettors and 10% goes to the bookmaker. Naturally the more money bet on a certain result, the smaller the odds on that outcome become.
