Sports betting is the activity of predicting sports results and placing a wager on the outcome. Sports bettors place their wagers either legally, through a bookmaker/sportsbook, or illegally through privately run enterprises referred to as “bookies”. The term “book” is a reference to the books used by wage brokers to track wagers, payouts, and debts.
Many legal sportsbooks are found online, operated over the Internet from jurisdictions separate from the clients they serve, usually to get around various gambling laws (such as the Unlawful Internet Gambling Enforcement Act of 2006 in the United States) in select markets, such as Las Vegas, or on gambling cruises through self-serve kiosks.[1]
There are different types of legalized sports betting now such as game betting, parlays props and future bets. They take bets “up-front”, meaning the bettor must pay the sportsbook before placing the bet. Due to the nature of their business, illegal bookies can operate anywhere but only require money from losing bettors and do not require the wagered money up front, creating the possibility of debt to the bookie from the bettor. This creates a number of other criminal elements, thus furthering their illegality. (資料來源)
投注串關:風險與回報
投注串關是一種特殊的投注方式,它讓玩家能夠同時選擇多個不同的賽事並組合成一個投注組合。這種方式在提高中獎機會的同時,也帶來了較高的風險。 舉例來說,假設你選擇了三場足球比賽進行串關投注,各自的賠率分別是2.00、3.00和4.00。如果你成功預測所有比賽的結果,你的最終獎金將是2.00 x 3.00 x 4.00 = 24.00倍。然而,如果其中一場比賽失敗,你的投注將全數失去,即便其他比賽預測正確。 雖然投注串關能夠帶來更高的回報,但風險也相對增加。因此,在使用串關投注時,玩家應謹慎選擇賽事,避免過多的串關組合,以降低失敗的風險。同時, 根據賽事的實際情況,適時地選擇合適的投注方式,有助於平衡風險與回報,實現更好的投注體驗。
Odds for different outcomes in single bet are presented either in European format (decimal odds), UK format (fractional odds), or American format (money line odds). European format (decimal odds) are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2.00 are an even bet.
UK format (fractional odds) are used by British bookmakers. They are the ratio of the amount won to the stake – the solidus “/” is pronounced “to” for example 7/1 “seven to one”. Fractional odds of 1/1 are an even bet. US format odds are the amount won on a 100 stake when positive, and the stake needed to win 100 when negative. US odds of 100 are an even bet. (來源)
