Below is a top five list of these offers:

  • Sign up Bonus
  • Free Bets
  • No Deposit Bonus
  • Deposit Bonus
  • Loyalty Bonus

Sign Up Bonus

The sign-up bonus is the type bettors get after they complete registration on a bookmaker. It’s a gift bookies provide new customers to incentivize them to start betting immediately after registration.

The sign-up bonus has become a mainstay in the betting industry, and, unsurprisingly, the biggest betting sites ensure it is as attractive as possible. Bettors often look out for the bonus and avoid bookmakers not offering it. While some bookies may require you to deposit some money in your bet wallet to receive and activate this bonus, others may not.

Those that require you to deposit money in your bet wallet have a minimum deposit amount. This amount typically depends on the biggest betting site you register with. But it’s generally a reasonable amount to help you claim the sign-up bonus and start betting. Note that this bonus comes with T&Cs, including wagering requirements and expiry date.

Free Bets

Free bets remain one of the most exciting bonus offers the biggest sportsbooks in the world give new customers. Bookies offering new customers this bonus usually encourage them to start betting without risking their money.

Existing customers also get free bets, but in their case, it’s a reward for consistent deposit and wagering. Whether a bettor gets free bets as a new or existing customer, the operator covers the costs.

Like other bonuses, there are terms and conditions for using free bets. Each betting company has unique terms and conditions for their free bet bonuses. So, ensure you’re familiar with them before you start using them.

No-Deposit Bonus

A no-deposit bonus is a promotional offer that the biggest online betting sites provide new customers. It’s a different bonus type because, unlike other bonuses that require a money deposit, it doesn’t. New customers get a no-deposit bonus for creating an account on a betting platform.

The no-deposit bonus comes in either a small bonus amount or in free spins for casino games. Whatever the case with your bookie, nothing changes the fact that you can wager on games without risking your money.

The biggest advantage of the no-deposit bonus is that it lets bettors explore bookies without making an initial deposit. However, like with other bonuses, the no-deposit bonus also has wagering requirements, among other terms and conditions. Ensure you know them before you start betting.

Loyalty Bonus

A loyalty bonus is the type of loyalty bookies offer consistent customers on their platform. It’s a reward for their consistency in depositing, wagering, and keeping a high account balance on the platform. For Hughes bookmakers, you need an invitation to get to their loyalty club.

It’s this invitation that qualifies you for the exclusive bonuses. You can enjoy an odds boost, higher payout, and abundant free bets, among other attractive perks of being a club member.

Points Betting

Introduced by the online bookmaker PointsBet, Points betting is a betting system that is based on the margin of victory or loss. In this method, your payout or loss isn't fixed. Instead, the closer your prediction is to the final result (margin or point spread), the larger your win. Similarly, the more it falls short, the more you lose. So, the system offers the potential for both significant wins and losses.

FIP in Baseball Betting

Fielding Independent Pitching in baseball is a statistic used to evaluate a pitcher’s performance. It determines exactly how good a pitcher has been independent of the contributions of other players on his team. This metric works by considering only factors like strikeouts, walks, home runs allowed, and any other aspects of the game that the pitcher directly controls. Keep reading as I take you through what ERA and FIP mean, how they're calculated, and their differences. I'll also explain how to use FIP in baseball betting and when to avoid it.

Rotation Numbers in Sports Betting

Rotation numbers in sports betting are unique ID numbers assigned to every sports betting event. These numbers are usually the same across all sportsbooks. They represent the same bet options regardless of where you place your wager.
